Would like to record my face with a webcam on my desktop. I have a white wall with some light blue texture in front of my desk. Can I use that as a diffuser? I dont want to invest in a soft box or umbrella. I just tried it with my yellowish incandescent desk lamp, and seems ok except the yellow tone, so I plan to buy a white led spot light. What do you think? I can also put some white paper on the wall where the light hits the wall.
Attaching a drawing of my setup.
