yeah, I realize that the first one is kind of hot but I thought it was a funny picture. I'm kindof proud of it because it was very hard to focus in such low light and it came out very crisp, I can actually see myself in his eye. Also, if I had used the built-in flash with him that close, it would've been just a white blob in front of a black background showing how nice bounce flash is.
I don't think I can change the aperture on the FZ20 with external flash. It pretty much locks at 2.8 @ 100ASA. I could be wrong but when I use "A" mode, it won't let me change the aperture.
I have been playing a lot and these are but a few examples, the trick is getting the right angle on the bouncehead for the distance and angle of the camera.
