I actually burned in the bottom of this shot, along with all of the other edges. I didn't dodge the head up a bit, which might have improved this, looking at it again today. Flattening the exposure didn't do much for me, it just looked like a shot of a snake - do you know what I mean?
These are with the sony H5, EXIF is embedded. The only thing that I did that wasn't stock was use a diffuser. The diffuser I use for macros is a translucent ketchup squeeze bottle that I have modified to fit over the pop-up flash. I've wrapped some of it in tape to prevent light from coming out behind the lens and causing lens-barrel shadows. The H5 has EV settings for the flash, I find that -0.7 ev and the diffuser make a good exposure for subjects within two feet. I always shoot in full manual mode, there is nothing better than having more control of your exposure and composition.
