Set up a quick lighting scenario. With my main lighting coming from behind. Fill light was set up using a bounce card (large white mat board) placed over my lens to bounce all that light back at me. It certainly made for a soft wrapping light - but honestly I would never shoot this way as I would be placing a large blocking piece between me and my subject ~ not at all engaging with my subject. It's bad enough that I feel my face is always behind the camera and lens when I'm making portraits. But to have an additional blockage separating us just doesn't work for me as a photographer.
Good learning exercise ~ chalk it up to experience ~ placed in the "not one of the best ideas" pile!
