Silhouette, as a shooting method, can be used in many ways. It requires photographers to use it flexibly in creative techniques and be innovative in creative ideas. So how to achieve results? How about a nice silhouette photo? 1. Fully display the physical characteristics of the silhouette theme and vividly combine the body and the background. It can be said that the body is the language and the background is the tone. This kind of language is sometimes silent than loud. It is up to the creator to figure out and understand. This is also That’s the beauty of silhouette photos. Since in silhouette photos, the subject basically has no color or detail, the requirements for the subject’s physical characteristics are very high. This requires the author to carefully select the shooting angle and subject form based on the effect of later performance to fully display the subject’s appearance characteristics. Strive for beauty and vividness. 2. The acquisition of silhouette photos makes full use of the difference in lighting between the subject and the background. Generally speaking, we can make use of the backlight at sunrise and sunset, because the light at this time is the softest and does not look dazzling. It is a good time for shooting. It usually only lasts about ten minutes. In addition, we can use outdoor and indoor artificial lighting. differences in lighting or natural reflections from the sky and water. 3. Exposure should follow the principle of "it's better to underexpose than to overexpose", and perform spot metering based on the bright part of the background. Only in this way can the subject be severely underexposed and form a strong silhouette. 4. When the proportion of the subject in the picture is too small, or the blank space in the picture is relatively monotonous, you can creatively use silhouettes as the foreground. The black silhouette can not only force the audience's vision to focus on the subject, but also The black silhouette also does not distract the viewer. We can even use silhouettes as the main frame to form various shapes such as square, circle or variation, so that ordinary scenes have a unique sense of form and increase the depth of the picture. Portrait Photography Tips - Metering and Exposure Metering: Usually when shooting portraits, the metering is done on the face, or even more strictly, on the eyes. Use center-weighted or spot metering to move the metering point in the viewfinder to the face. After measuring the light, move it to the correct composition and press the shutter. Since we usually use negative film when shooting portraits, it is best to overexpose a little by about 0.3 to 1 stop, which will give better results when developed. "Negative over, positive under" is a mantra that many photographers often say. Aperture When shooting portraits, I use a large aperture to achieve a shallow depth of field. It will stand out more when the proportion of the subject is not very large. Another advantage of using a large aperture is that when the weather is gloomy, the shutter speed will not be slower than the safe limit. What is the safe limit of shutter speed? It is a "critical value". A speed faster than this limit can avoid blurring of the picture due to shaking of the hand and the movement of the subject. However, the safe limit of the shutter speed varies from person to person. different. First, check whether the subject is moving and to what extent. For moving subjects, it is usually necessary to freeze the frame. 1/250 may be safer. If the subject is stationary, put the camera on a tripod, and freeze the frame for about 1/8 second. Even 1/4 second can be frozen. Next, we consider the stability of the photographer's own hand. Everyone's hand stability is different. About 1/60 second without blurring the picture is something everyone can achieve. For example, the stability of my hand is not very good, probably less than 1/30, so I have to use a tripod. Fellow colleagues may wish to try to see how safe their hand-holding is. In summary, when shooting a stationary model, It should be fine at 1/60 second for hand-holding. When shooting a moving model, use 1/250 second or more. Tips for taking pet photos The key to taking beautiful photos of pets is to capture their personality. When you find these cute little animals doing something unusual or very interesting, you can snap a photo at any time. For example, the innocent look of a kitten or puppy dozing off leisurely on their favorite mat is more impressive than the forced pose they pose. Don’t forget to use a close-up lens when taking close-up photos, because if your lens is too close to your pets, they will definitely not be posing like models or celebrities waiting for you to take pictures. Photographing pets with dark fur It’s more difficult to photograph pets with dark fur, so when taking photos of them you must pay attention to making the background appear brighter. In addition, when photographing pets, you should pay attention to the position of the shadow just like photographing other objects. When using flash, be careful not to make your pet appear "red-eyed".

You don’t need a flash when shooting in a brighter place. If you must use a flash, don’t let your pet’s eyes look directly into the lens. This can avoid the “red-eye” phenomenon. When taking "group photos" of several puppies or kittens, it is best to put them in a basket and let them cuddle up against each other, so that the shooting distance can be easily adjusted. If you want your pet's eyes to focus on the camera, gently call their name or use a noise toy to catch their gaze. In order to take ideal photos, you not only have to prepare enough film, but also have enough patience, because all the professional animal photos you see were taken by photographers who spent a lot of energy and time. When taking photos of children playing with pets, be sure to keep people and animals on the same level. If you have a larger pet, you can place him or her next to your child for an ideal composition. Take photos of your cat. Currently, more and more pets are kept in the family, including cats, dogs, goldfish, birds, rabbits, etc. As a member of the family, they are inseparable and add a lot of fun to life. Take good photos of them. It's also a pleasure. When photographing family pets, you must first understand their temperament in life, capture their special demeanor and characteristics, and use suitable props to arrange a relatively elegant and clean environment. Wait patiently, attract their demeanor, and go with the flow. Only by nature can you take vivid and interesting pictures. Shooting tools are also very important. For close range shooting, you can use a standard lens. But some animals can only be photographed from a long distance, so you need to equip them with a medium focal length, long focal length lens, or even a super long focal length lens, or use a zoom lens that can push and pull according to the movement of the action, which is more convenient. When using a zoom lens, it is generally fixed on a tripod due to its heavy weight to prevent shaking during shooting. The shutter speed should also be higher. When photographing small animals raised at home, you should combine them with the environment and show them as tame, kind, carefree, and just like members of the family. Observe carefully and wait for the opportunity. Take the shot. For example, when photographing puppies and kittens, you should capture their lively, cute, docile, and funny characteristics. Also pay attention to the color of their fur, choose a suitable background to set it off, and do not be obscured by a cluttered background. For example, if you are photographing all black or dark-colored animals, you should choose a bright background. If you are photographing all-white or light-colored animals, you should choose a dark background. Use a dark background to highlight the color of the subject animal's coat. In addition, they can also be equipped with appropriate props, such as playing balls and ladders, to show their naughty demeanor. You can also combine some performance projects with children or adults playing together to show a harmonious environment with family members. When photographing fish, it is best to use a rectangular glass fish tank when photographing fish raised at home. When shooting, you can insert a piece of glass into the fish tank and drive the fish to the front to shoot, so that you can capture the scene of goldfish swimming. If the surface of the glass negative tank produces reflections or reflects the shadow of the camera, it can be avoided by slightly selecting blocks on both sides of the fish tank. If you use the overhead shooting technique, you can use a large shallow dish or a white basin, place the fish in shallow water, and take overhead shots from above, which can also get good results. When photographing fish, you can use lighting sources from above or on both sides. Goldfish and tropical fish will look more beautiful under the light. Since the fish tank and water surface are prone to reflection, resulting in unclear pictures, you should use polarized lenses in front of the camera lens when shooting, rotate the lenses and adjust the shooting angle (45 degrees is the best) to make the picture clearest. However, polarizer has a certain light-reducing effect, so in order to ensure clear shooting, the camera should be placed on a tripod when shooting. Photographing Birds Photographing birds is more difficult than photographing animals because birds are afraid of people and will fly and jump when people approach them, making it difficult to photograph them at close range. Use a zoom lens when possible. Keep the distance between people, or hide it with only the camera lens exposed, mount the camera on a tripod and wait patiently, or remove some feed that the birds like to eat within a certain range. When the birds come to eat, seize the appropriate opportunity to take pictures. , take shots of birds landing, flying, and singing on branches. Photography Techniques of Outdoor Photography Outdoor photography is the most refreshing and natural style among all photography works, and is widely loved by people. In addition, every amateur photographer has a practice environment where he can shoot anywhere. Therefore, whether he is an amateur or a professional photographer, shooting techniques of outdoor photography are regarded as a required course.

Among various shooting techniques, why is the shooting technique of location photography the easiest to learn, but also the most difficult to master? This is because every beginner photographer learns in the outdoor natural environment according to the natural landscape state. Basic photography and basic exposure. Outdoor photography works can be taken naturally according to the natural conditions of the environment. There is no need to worry about designing the light environment or the conditions required for taking pictures such as backgrounds and scenes, so it is naturally effortless to learn. However, it is naturally not easy to obtain outstanding and outstanding works of outdoor photography that are unique or stand out. Because the photos taken under normal outdoor conditions are all of the same tone, it is difficult for humans to change the natural environment and obtain better photos. Although outdoor light sources are available everywhere and it is easy to take pictures, if you want to get a lighting pattern that Zhang Zhang is completely satisfied with, it is much more difficult than taking pictures in an indoor studio where the light source can be adjusted arbitrarily. The natural light source of the sun cannot be at our mercy. We can only try our best to use the knowledge we have learned in daily life and apply and master lighting techniques to produce better photography effects. Therefore, it is naturally not easy to take photos that surpass ordinary people when you cannot control outdoor natural light sources at will. Outdoor photography is easy to learn but hard to master, and that’s why. In addition, the same is true in the use of scenes and other photography techniques. If you simply take photos in their original state, it is of course easy to achieve. But if you want to stand out and take excellent photography, it is quite difficult. Because the natural scenes and lighting conditions cannot be changed and replaced at will by humans. Therefore, how a photographer captures the scene outdoors, how to control the light source, and how to modify the scenery to suit his or her ideal state is more difficult than taking photos in an indoor studio. Although the shooting techniques of outdoor photography are easy to learn but difficult to master, as long as you can grasp the learning essentials step by step, after learning the basic photography skills in the past, you can further start with composition, lighting, and then master various courses from the timing of taking pictures. Gradually, you will have to learn the outdoor shooting techniques of wedding and art photography, which is actually not difficult. After we have understood that outdoor photography has two characteristics: the easiest to shoot and the most difficult to shoot well, we can use these two characteristics to develop and enrich ourselves. The specific learning suggestions are as follows: 1. Take advantage of the easiest feature of outdoor photography to practice more. We already know that outdoor photography can be taken anywhere, and good photos can be taken. Therefore, with the natural guarantee of safety, as long as you understand the basic exposure photography theory, almost Anyone can become a good location "photographer". And if it is just a general photo that requires natural or formulaic composition, everyone can take it with confidence and boldness. 2. There are many types of photos that are more challenging and difficult to take, such as art-type photos with scenes, which are the most difficult to take in outdoor photography and have a high artistic taste. Although this kind of photos require deep skills in lens selection, lighting techniques, composition ideas, color planning, etc., through repeated practice, you can take photos with higher artistic value that are different from life photos or landscape photos. work. Once a photographer can break through the bottleneck of this photography technology, the artistic value of his completed photography will reach a higher level, which will bring joy and pride to the photographer that no amount of money can buy. Therefore, after photographers have accumulated a considerable amount of shooting experience, they should challenge more difficult types of photography in order to reach a higher level of photography art. Photography Techniques of Formula Composition Type Photos Characteristics and Style Analysis of Photos Simply put, any photo taken with the portrait formula composition method can be called a formula composition type photo. That is to say, in the photo frame, portraits are the main focus, and in the composition, photos taken with close-ups, half-lengths, thirds or full bodies of portraits as the theme can be called formula composition photos. This is a minor but popular photo type in wedding and art photography. When taking pictures, you can directly use short depth of field to blur the background and scene processing other than the subject. In portrait photography, this type of photo is the easiest to learn formula portrait photography. As long as you use a long focal length lens (about 250mm lens for the 120 camera, or about 135mm lens for the 135 camera), you can easily take this type of photo. When taking photos, directly apply the formula composition method, without paying too much attention to lighting and other photography techniques. The only thing that should be paid attention to is to change the shape of the characters frequently to avoid becoming a mediocre and unchanged composition.

Since this shooting method only relies on the short depth of field function of a long focal length lens and the effect of the formula composition method, its value in photography technology is relatively ordinary, and it has never been highly praised in the art of photography. But for consumers who generally only pay attention to close-up portraits, this is the most ideal and most popular photo type. Therefore, professional portrait photographers cannot dismiss it and should be familiar with the shooting techniques of this type of photo. Adapt to the needs of the photography market. Photography market reaction and discussion This is a very popular photo type in the photography market. It is a commercially representative photo in wedding and art photography. After all, every photographer who goes to a photography company likes to see himself being photographed in close-up photos like a star, rather than the daily life photos taken at home. Therefore, in each set of photography albums, most consumers will choose this type of photos, and the market acceptance ranks highest among all photo types. Explanation of key shooting techniques 1. Use a long focal length lens as the main shooting lens (approximately 250mm lens for 120-type camera, or approximately 135mm lens for 135-type camera), whichever has short depth of field function. 2. According to the principle of the portrait formula composition method, directly frame the composition of close-up, half-body, three-part body or full body, about 5-8 steps away from the subject, and you can easily take the picture. 3． When exposing, you need to open 1 to 2 more stops of aperture compensation according to the characteristics of portrait photography to make the face texture brighter. The soft and bright light on the person's face is the focus of taking this type of photo. 4. In order to create bright eyes, it is best to place a reflective board or white board in front of the portrait so that the eyes can reflect bright light points. 5. When printing, it is best to follow post-processing techniques and use soft focus processing to comprehensively soften the skin texture and achieve a soft and beautiful effect on the entire photo. 6. You should change the style or props of the subject characters more often. Otherwise, if you take a lot of photos, the visual focus will not change, and the shortcomings of similar composition, depth of field, and shooting techniques will be exposed. Produced by Beijing Happy Lovers Wedding Photography. Analysis of photo characteristics and style. Simply put, any photo taken with the artistic composition method of scenery can be called a photo of the artistic type of scenery. Most of the pictures show both portraits and scenery. That is to say, when taking pictures, the pictures are not mainly portraits, but more focused on the dual expression of portraits and scenery, and the photos are interpreted from the perspective of artistic creation. It does not have certain composition, lighting or other formulaic techniques. It relies entirely on the photographer's own attainments in artistic photography to give the photos vitality. Therefore, mastering the dual artistic expression of portraits and scenery is the greatest feature and value of this type of photos. Since this type of photo requires a very large actual scene, it is the only type of photo that is difficult to express in studio photography. It is only easy to complete when shooting on location. When taking such photos, if there are no breakthroughs in composition, lighting and other photography techniques, they will become ordinary travel photos or life photos. The success or failure of art is often only a thin line, and anyone with certain photography abilities can understand this key. However, if the composition ability is outstanding and the lighting and other photographic techniques are handled properly, one can reach a very high level of photographic art. Therefore, the photographer’s shooting skills play a decisive role in shooting. Photography market reaction and discussion People with certain artistic appreciation ability like the beautiful artistic conception of such photos, but it is not easy for ordinary consumers to appreciate such photos. Because the proportion of portraits in such photos generally accounts for less than half of the frame, and does not have the close-up feel of ordinary celebrity photos, most consumers are unwilling to spend money on photos that do not have their own big heads. Unless you meet someone who understands the taste of photography, try to take as few artistic photos as possible to avoid serious frustration due to not being appreciated by ordinary consumers, which will affect the correct goal of pursuing artistic expression. Explanation of key shooting techniques 1. Design the style of the theme portrait, choose a scene suitable for the overall performance, and do the preliminary theme and scene design work. 2. In daily life, you should cultivate your ability of aesthetic composition, and make a good overall composition plan between the subject portrait and the scene when shooting. You should not fall into the cliché of formulaic composition of portraits and take close-up photos. 3． Analyze and use the on-site lighting situation, use addition and subtraction methods to integrate the subject of the portrait to be photographed, and control the outstanding expression of lighting in the scene environment without falling into the common problem of flat lighting in general commemorative photos. 4. Control the length of the depth of field to create a moving and high-level depth of field expression, and don't fall into the messy pattern of ordinary life photos.

5. Choose the most appropriate photo opportunity to press the shutter, capture the vividness of the portrait and the artistic sense of the scene, and shoot a perfect portrait with a scene. Photography techniques for black and white process photos. Analysis of photo characteristics and styles. Black and white process photos are taken with black and white negatives. After the negatives are developed in a single process, in addition to developing pure black and white photos, they can also be printed in color. A printing process that produces a single-toned colored photo on color photographic paper. This process can be handled by ordinary color printing. These single-tone photos can also be changed into any other single-tone photos through color correction during the same color printing, such as single red, single orange, single yellow, or single blue, etc. This type of photo is commonly known as a black and white photo. The monochromatic feel of this type of photo can give people a more unique feeling, and it is an indispensable type of photo in wedding and art photography. Photography Market Response and Discussion Anyone who knows photography knows that black and white photos are quite durable and can be changed into any other monochromatic picture. Therefore, this type of photos is also very popular in the market. Just from the perspective of wedding photography, if you take too many photos, you will lack a sense of joy, so you should choose an appropriate ratio of photos for customers. Not too much, and not entirely nothing. Explanation of key shooting techniques 1. When taking this type of photo, the most important thing is the choice of film. As long as you use black and white film, you can develop the tone of this type of photo. 2. During the shooting process, you should pay attention to the color of the background and props, preferably gray, because too dark or too white backgrounds, props or costumes will cause the photos to appear all black or all white when they are printed. This is a Common sense about black and white photos. Only when the gray tone is appropriate, a single tone overprinted by color printing can have rich gradation expression. 3． When taking black and white photos, you can get beautiful tones by controlling the exposure correctly. It cannot be compared to the color negative film shooting method commonly used for portraits, which often uses two or more stops of exposure compensation. Only correct exposure can avoid the loss of saturated tones. 4. Currently, there is another type of film produced by ILFORD manufacturer on the market, which can be printed directly in color without having to go through the manual development process of black and white liquid. The shooting effect is the same, and it is a more convenient film. 5. The negatives that have been photographed and developed can be developed into pure black and white photos through the black and white development process. Or through the color printing process, a single-tone photo can be developed. Full color performance. Its biggest feature is that it produces extremely bright tones on the screen, and the black and white contrast is extremely large, and the exposure latitude is also extremely wide. The shooting techniques of negative process type photos. Photo characteristics and style analysis. Positive film and negative process type photos are taken with positive film. , when developing the film, the regular E-6 developing solution is not used to develop the film. Instead, the C-41 solution used for negative film is used to develop and process the film. Therefore, the original normal positive film becomes a negative film. Using This kind of color film base cannot obtain normal colors, but becomes extremely bright colors. Among all professional wedding photography and artistic photography techniques, it is the most difficult type of photography to control exposure. Photography market reaction and discussion: It is more difficult to control the exposure of such photos, but if the shooting is successful, the picture will appear unique and eye-catching. Therefore, both the response from consumers and the evaluation from professional photographers in general are quite high. It’s just that there are not many photographers who can take this type of photos well. After all, it is not like the 160-degree film used in professional portrait photography. It has a huge exposure latitude and low contrast, making it easy to shoot soft portraits. In addition, in order to avoid complicated exposure and light ratio and prevent failure, most photographers tend to stick to the easier-to-shoot portrait formula composition type of close-up photos. Therefore, most of the photos of this type currently owned by consumers are close-up compositions, and it is difficult to have high-level works that surpass this composition. In fact, when taking such photos, if you can switch to a portrait-with-scene artistic composition and master the scene, lighting ratio, color planning and other techniques, the color and saturation of the work can surpass the portrait formula composition. The level of type photos reaches the pinnacle of portrait photography art. Key points of shooting and description of techniques 1. There are two key techniques when shooting. One is the appropriate selection of negatives (actually positive films).

In a lighting environment with abundant light sources, or when you want to achieve strong contrast and perfect portrait texture, you can use medium or low sensitivity positive films to shoot. For example, using 64-degree and 100-degree positive films, you can get very saturated and gorgeous colors. hue. However, the exposure latitude of a positive film with this sensitivity is extremely narrow. If the light ratio is not controlled carefully, the exposure will fail, resulting in underexposed dark brown or overexposed dead white. To avoid exposure failure, or if you want to get soft contrast in the photo, you can use a positive film of about 200 degrees or 400 degrees to shoot. Currently, the 200-degree slide film is the most popular on the market because it has a wider exposure latitude. Wide, it is the type of film that is easier to shoot and has softer contrast. It should also be noted that the positive films of some brands will tend to be extremely yellow, or magenta, bright green and other tones after such abnormal processing. Of course, this is also related to the color temperature when taking pictures. All in all, photographers should adjust according to their own preferences to obtain the ideal color tone. 2. The second is the control of light ratio. When taking this type of photo, the light ratio throughout the entire picture must be calculated perfectly, that is, the contrast between the bright and dark parts should not exceed three stops, otherwise it will form an extremely black or extremely white high-contrast phenomenon, making the picture Midtone color is lost. Especially when shooting white dresses in wedding photography, if the light is not controlled properly, there will be only dead white without any mid-tone layers. It is best to open one more stop for the overall negative exposure in order to get the most saturated colors when developing the photos. The most taboo thing is underexposure, which will cause the photo to have an ugly dark brown tone. 3． During post-processing, try to use soft focus printing as little as possible, otherwise it will be easy to form black hair on the face of the portrait penetrating into the white area, which will become an extremely weird phenomenon. This is an inherent phenomenon of soft focus printing during general post-processing, but it is more prominent in positive and negative-process photos. Photography techniques for coarse-grained texture photos. Analysis of photo characteristics and styles. Coarse-grained texture photos mean that the image particles on the photo screen give people a rough feeling, similar to the special effects produced by screen processing during printing and enlargement. It is different from other The type of photos that pursue saturated, detailed texture. Because the image grains of this type of photo are coarse and the density is not enough, the contrast between black and white is not great. The dark parts of the photo will not appear too dark and the bright parts will not look too pale. The colors and tones of the entire picture are flat and soft. A more elegant and artistic type of photo. Photography Market Reaction and Discussion Generally, people with unique and elegant personalities can appreciate the style of this type of photos. Most elegant people who have studied photography also have a special liking for this type of photos. However, some people who lack ideas about photography and art often cannot accept the rough texture of the picture. They think it is caused by amateur or non-professional film shooting, and even think that the photographer is cutting corners. Therefore, when taking this type of photos, it is best to understand the artistic quality of the client to avoid being self-defeating and in vain. Explanation of key shooting techniques 1. Using ultra-high-sensitivity film shooting method: This is the simplest method to obtain rough grains in the image. Those who like this kind of photos can choose high-sensitivity film when shooting, such as film of about 800 degrees or 1600 degrees, and use a 135mm camera to shoot. The effect will be more obvious when magnified. When developing photos, because the photosensitive emulsion of the film itself is already high-sensitivity rough particles, it is natural to obtain images that are rougher than ordinary films. Moreover, when a small negative film is enlarged into a large photo, the rough particles will be more obvious (the benefit of 135 film...). 2. Use the film intensification and development method: that is, you use a film that can be intensified at about 400 degrees to shoot, and deliberately underexpose it by about two stops. The underexposed part is compensated by increasing the development time during the film development process. As the film stays in the developer for a longer period of time, the photosensitive particles will become coarser. This is the commonly used intensification development method. Those who use this method need to remember the exact number of underexposed stops when taking pictures, so that they can ask the printing company to compensate according to the formula. Since the new films introduced by various manufacturers now have very detailed image quality, this intensifying development method seems to be less effective; but in the past, this was the most commonly used technique in the photography industry. 3． High-magnification enlargement: that is, taking advantage of the characteristics of the film that makes the image grainy when enlarged at high magnification, to achieve the effect of coarse-grained texture. Generally, when a negative is enlarged or the magnification is more than twice, the image grains will become coarse due to the enlargement, and at high magnification, it can be clearly seen with the naked eye.

4. You can also use techniques such as rough lenses and screen printing to obtain photos with the same coarse-grained texture. No matter which method is used, it is best to keep the exposure slightly lower than one stop when shooting, so that the printed photos will be more coarse-grained. (The dog head can be of great use~~~) The shooting techniques of constant light fill light type photos. Photo characteristics and style analysis. In outdoor dusk, sunrise or weak lighting environments, fill light must be used to achieve the best results. Take perfect portrait photos. If a general flash is used as a fill light source, the atmosphere of the picture will be insufficient due to the large scattered light area. Professional photographers generally use 3200K constant lamps as spotlight fill-in light sources. When projected by such a spotlight-type constant lamp with a yellowish color temperature, the subject's face will be brighter and yellowish, while the background will be darker and more natural. sense of specialness. Because of its unique performance in color temperature and light ratio, it is a lighting technique often used in outdoor photography. Photos taken with this method are generally called constant light fill-in photos. Explanation of key shooting techniques 1. Photo timing: This type of photo is taken about an hour before or after sunrise or sunset, and the effect is more perfect. At this time, the sky or environmental state is a lighting situation with low light value, so the fill-in light effect of artificial light sources can be displayed. It is also ideal to use this lighting technique in woods and places with poor lighting. 2. Prepare spotlight-type constant light equipment: You can purchase a DC sunlamp for video recording, but the lampshade needs to be changed to a four-blade cover that can adjust the projection area. Otherwise, the light source scattering area will be too large and it will have the disadvantages of ordinary flashlights. You can also use car headlights instead. The spotlight projection effect is also good, but the light value is weaker (usually 50W quartz lamps). When taking pictures, you need to increase the exposure time to compensate, or replace it with a larger power one. Quartz light bulb. 3． Other equipment: When taking this type of photo, since the brightness of the subject and background is very weak, you need to bring a tripod to prevent vibration. You should also bring a light meter and a filter that can change the color temperature. Using the C12 blue filter can change the yellow-orange color temperature of 3200K into a more normal color temperature of about 5400K. You can also ask the printing company to correct the photo when developing it.
