Can incandescent lamps be used for photography?

Yes, depending on what you want to shoot, you'd better add a cover. In addition, the color temperature of incandescent lamps is not easy to locate. If you shoot with an incandescent lamp, don't put the light source directly on the top or plane. Oblique lighting or 30-60 degree side lighting can be used. When lighting a lamp, you can use a paper shell to block the edge, and you can cover the lamp with paper with good light transmission (a single layer of paper towel is enough, and a heart-to-heart one is good), otherwise the light source is too strong.
