The white balance advice was huge. I guess I was inadvertently doing this when I took photos of my minis, because I would always focus on a white object and then shoot the mini, though this would sometimes cause some blur because my focal point wasn't always directly on the mini.
He has it right when he says that natural sunlight is best. And yes, it moves and can be problematic. However, I will just try to be patient at this stage. I will either wait for a cloudy day or shoot at dawn because the sun is naturally filtered at these times. After spending 3 months painting a mini, I have no problem waiting a few days for the right conditions to photograph in.
Yes, his photo sucks because half the mini is obscured in darkness. This destroys his picture, that's for sure. If you want a black background, use a black background. I found that black poster board and black cloth does not work. Sections of it are too gray. Instead, use a blacked out TV screen or computer monitor. Your mini will glow in front of it under the right conditions.
For me, this is what it is all about. Getting the mini to glow. Once I have this, and my highlights are blinging without being too harsh, I know I have the right conditions. For some reason, shooting in front of a glass door or window always produces the best results for me. However, I haven't found a way to shoot like this and then underlay a white/black/colored background.
