1. When using Polaroid camera to shoot some people at night, facial blur or other strange phenomena may occur due to improper use of flash. In this case, we usually block the lens of Polaroid flash with one finger, but there is a small photosensitive device on the left side of the flash, so we should not block it with our fingers.
2. If we shoot indoors, we just need to use a piece of toilet paper, fold it into two layers and cover it with Polaroid flash to make the lighting soft and natural. But don't cover it completely with your fingers. If there is no light in the flash, the scene will turn red.
