If you use a light box, you can choose a constant light or a flash. These two kinds of lights have their own advantages, so you need to choose according to the actual situation.

The advantage of always-on lamp is that what you see is what you get, the light is generally soft to scatter, and the color temperature is low (yellowish) and it feels warm; Disadvantages are low brightness, long exposure time and easy jitter.

The main advantage of flash is high brightness, which can prevent camera shake; However, the light concentration is high (usually a little explosive), the color temperature is high (blue), and the effect is difficult to predict (or it is difficult to measure light manually). ).

If you use it frequently and have high requirements, you can consider flash+light box+background paper.

If the camera has a warm boot, choose the studio light, 80* 150 soft box. U2 is too expensive, and it is a famous brand of outdoor lighting.
