Question 2: How to shoot the shutter of Peony 400 in the early morning with P-block and rest for 35 degrees (with supplementary light)
Question 3: How to shoot peony flowers well? How to compose a composition? Light requirements? When is the best time to shoot? It is better to shoot sideways, with distinct levels and three-dimensional sense; The composition should not be too full, too straight, too full, too blocked, too rigid; The shooting time is better in the morning and evening, the light is softer, the noon light is too bright, and there is no dark side and layering, so it is better to shoot with backlight and side backlight or side light.
Question 4: How do chrysanthemums and peonies regulate the flowering period through temperature and light ① The influence of light on the flowering period.
The vast majority of flowers can only promote the formation and flowering of flower buds under the condition of sufficient light. Different flowers have different requirements for light. Impatiens balsamina, Cuiju, Gladiolus and other long-day flowers, their flower buds need to be exposed to light 12 hours a day, and the longer the sunshine, the faster the development, the fuller the inflorescence and the gorgeous colors. If this condition cannot be met in the development period, it will not bloom or delay flowering, and the branches will be thin. Short-light flowers, such as crab claw orchid and poinsettia, require sunshine hours within 12 hours per day for the formation of flower buds. If they are under long sunshine conditions, they can only grow nutritionally without flowering. Therefore, the flowering period can be controlled by light treatment. Short-term illumination treatment and short-term sunlight treatment are suitable for chrysanthemums, poinsettias, cyclamen, violets, etc. Flowers. This kind of flowers require less than 12 hours of sunshine every day to bloom normally. In order to make short-day flowers bloom ahead of time, it is necessary to shade them so that they can stay in the stage of flower bud differentiation and flower bud formation and accept short light conditions for a long time. The specific method is: when the flowers grow to a certain stage, under the premise of strong growth, cover the whole plant tightly with black cloth or black plastic, shade it, and control the illumination time within 8-10 hour every day for about 50 C 60 days, so as to achieve the goal of early flowering.
Long-mouth illumination treatment Long-light treatment is suitable for some flowering species in early autumn and summer. These flowers need oral illumination for more than 1 2 hours every day to bloom normally, and do not bloom in winter or early spring under short sunshine conditions. If the flowers with long sunshine need to bloom ahead of time, in addition to the appropriate temperature and humidity for flower bud differentiation, it is necessary to make up the light, such as Guayeju, Gladiolus, tuberose and so on. The specific method is: after sunset, use artificial light sources such as incandescent lamps or fluorescent lamps to supplement the light, and keep the daily illumination time above 15 hours, continuously? The purpose of early flowering can be achieved in a period of time. Epiphyllum is a plant that blooms at night, but it can bloom during the day for people to watch through the light treatment that is reversed day and night. That is, when the flower bud is 6-10 cm long, the epiphyllum will be placed in the dark room during the day and irradiated with high wattage light at night. After 4-5 days, the county flower will bloom during the day.
② Effect of temperature on flowering period.
Some flowers are insensitive to the length of light, but sensitive to the temperature conditions in the opposite place. As long as the temperature is appropriate, flower buds can differentiate and bloom. Conversely, if the site temperature is artificially controlled to be too high or too low, flower bud differentiation and bud formation can be inhibited, thus delaying flowering. Flowers that can form flower buds at higher temperatures, such as rose, Milan, jasmine and Catharanthus roseus, take shorter time to form flower buds at higher temperatures, and take longer to form flower buds at lower temperatures. If you want to make it bloom in advance, you can heat it in advance. Most tropical flowers that like temperature, subtropical flowers that are not cold-resistant and flowers that bloom in spring in warm zones can make them bloom ahead of time by increasing the temperature. At the same time, warming can also make these flowers, which are dormant in winter but have formed flower buds, bloom ahead of time, such as plum blossom and winter jasmine. After frost and snow, they will be moved indoors, gradually warmed up and kept for 8-250C, and their flowering period will be advanced. Increasing or decreasing the temperature artificially can break the sleeping state of some flowers and change their flowering period. For example, when it is hot and hot in summer, the upside-down golden bell is placed in a shady place with low temperature, and after several days, it can break its dormancy and enter the flowering stage. The flowering stage of Magnolia grandiflora will be in early spring next year. If Magnolia grandiflora with completely differentiated flower buds is selected for heating treatment in winter, it can break its dormancy and bloom ahead of time. Lower temperature can not only inhibit flower bud differentiation and bud formation, but also delay the flower opening time. For example, tuberose can keep unopened buds 1 week in a low temperature environment of 5-10℃; Temperature reading below 3 C 4℃ can prolong the flowering period of gladiolus, below 4-5℃ can prolong the tail flowering period, and below 10℃ can prolong the flowering period of hydrangea.
Question 5: Peony flowers photographed by mobile phone are called photos? Or a picture? Does that name feel appropriate? When it is developed, it is a picture.' What is saved in the mobile phone is a picture.
Question 6: Make the final drawing of Chinese painting effect with peony photo ps 1. When drawing petals with lasso tool, you must draw the * * * shape of petals, so as to copy the deformation in the next step. 2. Fill in white, the purpose is to prevent transparency and bottom for the next copy. 3. Fill the red with the gradient tool. Pay attention to the color gradation transition of petals and the light receiving surface.
Question 7: Q: Look at the picture and guess the real thing. This is a partial shot. Look at the whole picture. It's not just flowers. Please say the conscious detour of roses and peony flowers. All-round basket counting
Question 8: To see peony flowers, can I take photos in this dress? Black and white with peony can be photographed better.
Peony is relatively bright, with bright flowers, jade smiles and pearls, romantic and elegant, and is known as the "king of flowers". In the cultivation types, it can be divided into hundreds of varieties mainly according to the color of flowers. "Peony has many varieties and colors, with yellow, green, fleshy red, crimson and silvery red as the top grades, especially yellow and green.
