What is the difference between flat light and sandwich light?

Both flat light and clip light are photography lighting techniques, not just for children’s photography.

Large flat light is also called world light. It mainly requires a large area of ????area light in the front direction. The characteristic is that the picture is transparent, there are not many dark dead spots, and the performance of skin, color, etc. is relatively good.

Clamping light, as the name suggests, is the light on both sides of the subject. The light gradually changes from the edge to the center, which is better for showing a three-dimensional effect, but it will cause texture and color changes on the skin. question.

As for the implementation method, I will post a Q&A in your other thread.
