What we are going for is a photo light box. You can spend a fair amount of money buying something right off the shelf at photography specialty stores. Given that LEGO is an expensive enough hobby, I wasn't looking to try and break the bank. So, when the going get's tough, the tough get going...to IKEA. There are several IKEA hacks like this one on instructables.com.

To modify the hamper I rolled the top of the hamper and clipped it to the side of the box. The divider was unzipped and then secured to one side with Velcro strips I had left over from another project. The hamper will eventually sit on one of the narrow sides.
I then ran out to the store and bought two sheets of poster board in white and light blue. These were cut to fit as backdrops that ran along the bottom of the box itself. I would recommend buying a few more colors of poster board and experiment for the best effect. I personally found that the light blue backdrop had the best effect.

As a final step I turned on my camera's macro setting and turned off my flash.
So how did the picture turn out? Take a look. I'm not going to quit my day job to become a professional photographer, but its a definite improvement. I now feel confident that I've got the tools to take a proper picture.
