thought i had better make an effort to show this technique seeing as i am hosting the challenge, this is a gif file, so best viewed in its own page. here i am with my cardboard and aluminium foil . sitting side on to window light, you can see how the reflector fills out the shaded side of my face and takes the sunken cheeks and lip creases out, and highlights the cheekbones... *yawn
It's an illuminating gif! (Sorry, I couldn't help myself). You really can see the difference it makes. I even have a "real" one that I never use. I'll try to do some this weekend.
Most definitely an effective method of demonstrating this technique. I was glad to see your including the explanation as well as the gif. It's on my list to try now. Thank you,
