Or otherwise obscuring it? I was experimenting with deflecting the flash with a piece of white card stock about the size of a business card. I had it about 40-45 degrees away from the flash, so the light would bounce up. However, when doing this, it seemed to make the flash a bit warm to the touch. Is this ok, or can I damage my flash like this? I only did it a couple of times and stopped when I noticed the heat. Is this normal? Thanks!
