Thanks for the comments, everyone :)

I also used a new flash diffuser I designed that works a little differently from others I have seen. I wanted a way of eliminating hot spots in the output, so I designed it to use bounce flash instead of direct flash. The result is perfectly smooth light output over the entire surface of the diffuser. I haven't used it much yet, but all the shots in this series use it, and I really like the light from it so far. It is just slightly brighter on one side than the other, so you still get a little bit of texture out of the shots, even if the diffuser is pointed straight forward.

If you're interested in a tutorial on how I made it, check out the Flickr link below. I may put a post in the Macro Discussion message board as well to help anyone interested in this design:

Thanks for this link Ryan.

Am I understanding this right? --> The semicircular channel you have is sealed using a manila folder and tape? So your "box" is an enclosed volume with no openings, and the light falling on the subject is the light that transmits through the curved manila folder channel?

Not quite. The box is totally enclosed, but the light falling on the subject comes through the white piece of paper covering the front of the box. The curved piece used to seal the channel at the bottom is covered on both side with aluminum tape and therefore completely opaque. However, to the left and right of the channel is open within the inside of the box, so some light hits the subject from the sides of the lens in addition to the majority of the light coming from above the lens.

Ah! I understand now... so the left hand side 'wall' in your first picture in that link is the paper the light transmits through. It was kinda hard to make out paper from the aluminum on my monitor here :)

Thanks!

Sure thing. I really should have posted some shots of the inside as well to make things more clear, but I didn't think to take a photo of it until it was already finished!
