Sigh. I purposely set my exposure to ISO 200 before I started, as my homemade light tent (now down to $11/use!) is fairly tall for this application. After fiddling with the lights, I should have reset to 100. I didn’t realize how much noise crept in to a flat color shot with the 5D until after I had taken down the setup.

It’s not too noticeable at this resolution, but it’s more annoying the larger it gets.
