Here's the first series of tests that I did for the DIY flash bouncer. I forgot to reduce the ambient light in this case and so the flash served mostly as fill flash; I will correct this in the next batch.
The first image was taken with the flash directed at the ceiling of my room.
The Second image was taken with the flash bouncer + flash directed straight at the subject.
Without reducing the ambient light and making the flash the sole light source, I guess the pictures look a little weird. Even so, I think I prefer the second one with the bouncer.
I will post other pictures tomorrow.
