Why a lightbox? Well, I've been working on swaps with countless failed attempts to match the quality of the lovely items I've received, that I gave up and stuck to what I do best — sprawl on my couch with my laptop. I started designing 3D models and have 3D printed some bookcases, side tables and vases. After I finish polishing up the details on the prototypes, I plan to open a shop in late January or early February. More details on that later.
DIY Lightbox Tutorial and Cheap Lighting Rig
For the lightbox you will need: Box (at least 12"x12"x12"), ruler, pen/pencil, tape, utility knife/razor blade, poster board/bristol board 22"x28", glue/spray mount, scissors, and (not pictured) linen or cotton fabric or tracing paper/parchement paper. For the lighting set up: 120 watt daylight R40 flood light, assorted PVC pipe and plumbing fixings, and (not pictured) 8 1/2" clamp light.
I started with a 12"x12"x12" box, you can go bigger but I wouldn't go any smaller. (If you are going to build the lighting rig too, don't go much higher than 12" or you'll need to get taller poles to fit the light over the box.) Cut off two of the flaps. Some people cut them all off, but you can use them for light control to block your camera from any side lighting sources, so for now I'm keeping them, but if they get annoying I'll slice them off later. Next cut out three of the walls. To maintain the integrity of the box, I marked the holes 2" from the sides and 2.5" from the base. Some people cut them smaller to allow more light in, but structurally, I think this will hold up better when I inevitably trip over it.
Your box should look like this. You can leave the interior unfinished, but if you line the inside of the box with white poster board it will help to bounce the light around the interior of the box and remove shadows*. It does make a difference, so do it, it's worth the time, trust me, (famous last words).
Before cutting up the poster board to cover the interior, cut one long piece for the infinity curve. 11 3/4" (or lightly less than the width of your box) x 28" (not pictured, sorry). It should be the width of your box, and the length should be extra long so when you put it in your box you can adjust the curve with the extra paper that will be sticking out. I also cut out different colors for backgrounds as seen in the photos below.
Back to the interior. Measure twice, cut, then label the back of the piece you are gluing to a corresponding number on the box interior. I used T L R for Top, Left, Right and N S E W for North South East West, to help get all of the right strips in the correct place and to glue the correct side. You could use numbers, whatever works for you. I used a repositionable Spray Mount adhesive (aka Artist's Adhesive), you could use a glue gun. Don't use glue sticks, they make the edges curl up, and Elmers type white glue can soak in and warp the poster board. (I forgot to line the inside of the flaps, but I'll add that later.) Note: if your white poster board is glossy on one side, use the glossy side on the interior to bounce more light to the center, use the matte side for the infinity curve.
Some people suggest using tracing paper or parchement paper to cover the holes to filter the light, it's cheap and works but I think fabric works better. I tried an old white cotton t-shirt, and cotton diper cloth with a woven linen look to it (this one worked the best for me). Other suggestions are white muslin, linen, fleece, any white fabric with some texture to diffuse the light. Cut your fabric and tape over the holes. I used blue painters tape, so I can easily remove the fabric to test different filter options.

For the lighting rig, look for 1/2" PVC pipe in the plumbing department of your local hardward store. I built this in the aisle, testing which pieces made it the most stable. Below are the pieces I used.
Lighting Rig Supplies used:

• Two 1/2" side outlet elbow, 45 ~ $1.29 each
• Two 1/2" triple slip tee ~ $0.35 each
Assorted PVC pipe (cheaper to buy one long pipe and cut to the size you need, but I bought pre-cut)
• Four 1/2" x 18" PVC pipe (plain-end, white for the legs/base) ~ $0.32 each
• One 1/2" x 24" PVC pipe (plain-end, white for the cross bar) ~ $0.42 each

Buying time: 20 minutes
Build time: 15 minutes
Total lighting rig cost with one light: $28.72 + tax
All of the photos taken below are with the one single overhead light source, but with this lighting rig you can also add side lights. I'll post pictures taken that way another time.
Things I Learned* Pictured on the left is the lightbox with the plain brown cardboard interior not covered, and second, is after I lined the interior with white poster board. Click on the pictures and toggle back and forth. If you look at the sides of the images, you'll notice the difference in lighting. The plain brown cardboard interior is darker around the edges, so I definitely think it's worth the time to line the whole interior. The black bookcase is one of the pieces I made based on a bookcase I saw on Orlando's blog, HommeMaker. This prototype turned out too thin, but I'll be making a thicker version that will be for sale in my store next year.
The slant bookcase I miniaturized for Meagan from a design by David Ngo. If you click on the image, you can see the differences between filters. Subtle, but check out the shadows on the middle shelf. After testing a variety of filters, I'm sticking with the cotton fabric with more of a woven linen texture.
The tree was a gift from minimodernistas, I'm not sure where Doris got it, but it's aweseome. Here I swapped in a different color 12" x 28" sheet of poster board for the background. Having one black and one white background should suffice, but I got the blue, silver and gold to have more options to work with. If you compare the shadow under the tree you can see the difference between the filters. I prefer the more diffused light with the cotton linen. Hit me up with any questions, otherwise good luck and good light. :)
(On a separate note; my brother is an uber talented professional photographer, cinematographer and artist; he set up the lighting and took the photos that won third place in the FDQ contest. He had suggested the PVC pipe lighting rig, but I forgot exactly how he said to build it, so I made do with the above set up. I'm going to have a 2.0 version with advice from him. Stay tuned. :)
Hope this gives you more light for the new year! Peace out.
(Make sure you read this post with more details on the infinity curve and turning the lightbox into a storage box for your lights.)
