How to eliminate shadows when using flash photography

It should be the shadow of the camera. If you sometimes use the camera's own flash to shoot macro, it is difficult to illuminate the whole picture because the position is not high enough.

Solution:

1. Don't use the lens cover, or the shadow will be bigger.

2. If you must use your own flash, you can try to adjust the light path irradiated by the flash to make it diffuse to illuminate the subject or try to illuminate the subject from another position by reflection (for example, adjust the light path appropriately with white paper).

3. Use external professional flash to illuminate the main body (this kind of lamp is big and high, and it is relatively difficult to form shadows).

The best way is to use a professional macro flash, which is bright and uniform, but the price is very high.
