1. First of all, don't seal all the windows of the studio. Windows in the southeast and northwest can have different lighting effects. East-west windows can have the effect of low color temperature light. North-south windows are white, and windows facing north on cloudy days will also have strong directionality. Set up your own lighting system, you don't have to buy special lights. You can use your own flash. Keep the flash away from the camera. Connect the camera and the flash with a sync line. If you want to use two flashlights, you need to connect a flash synchronizer to one of them. This will ensure that the two flashlights are synchronized. For convenience, both lamps and cameras need shelves. And can be adjusted.
2. Make some small accessories to improve your lamps. Such as; Add diffuse white cloth and transparent drawing paper in front of the lamp. Turn the strong light of the flash into scattered light and soft light. You can also add a bucket-shaped hood in front of the lamp to turn the light of the flash lamp into a spotlight. Strengthen the directionality of light. The intensity of flash can be controlled by the distance between the lamp and the object, and also by controlling the luminous intensity of flash. Let one flash emit full light, and the other light only emits 2/3 light or 1/3 light. Control the light ratio of main light and auxiliary light.
You need to prepare a piece of white foam plastic as a reflector in the studio.
Nowadays, digital photography appears more and more in our life. Digital photography also simplifies the lighting of people's own studios. Because the digital camera has the function of white balance, you don't have to worry about the color temperature of light. You can safely use incandescent lamps. Daily table lamps can join the ranks of backup lamps. But don't use two lamps with different color temperatures at the same time. Digital photography requires higher brightness of light than film photography. The light ratio should not be too large. Generally, it can only reach 1: 32, black and white for film photography can reach 1: 128, and color can reach 1: 64.
