I didn't build it but bought it.www.ezcube.com
The table top studio.
The cube is the medium size but you could do the small but if you want to take pics of big pieces the medium is better.
You can use your own lamps but I really recommend the Daylight Trumpet bulbs. Yea they are $30 each but there good for 10,000 hours and well balanced.
The once comment on bulbs I have is that you need "matched" bulbs. Todays digital cameras try to white balance for you. That is to make corrections in the wavelengths to give you a perfect shot. You often see shots w/ lots of yellow or lots of Blue - white balance issue.
So if the camera has a flourescent light on one side and and incandescent on the other it "confuses" the digital processing. The same is true of 2 incadescents of different wattages and/or different manufacturers. Even different batches numbers of bulbs can have different wavelenghts.
So match your bulbs and learn to set your W/B if you have it. Manual w/b is better even then the ones that let you set to the type of bulb. For instance you'd set the bulbs I'm pimping to Daylight setting, not flourescent b/c that is the spectrum they produce.
I have 2 backgrounds - blue gradiant and black gradiant both purchased from EZ cube.
I have a new 8.0 MP camera from Olympus (upgrade from my 4.0 this year) and a tripod.
I've got some pics of it somewhere. I'll see what I can find.
