If you want to shoot photos of objects and products with little to no shadows, then one of the simplest ways to do it is with a light box or light tent. This is a white box with an opening in the front and with translucent white panels on each side that allows bright diffused light to bathe the subject in what can be a shadowless lighting effect.
The guys over at DIY Tryin created a tutorial video on hacking together your own light box/tent on the cheap. What they try to emphasize is diffusion. In order for a light tent to really work, you need to diffuse the light coming in from all sides. But as they were able to demonstrate, the light is so diffused that they can shoot an image with their phone and get something very diffused.
For what it’s worth, we would rather recommend having a three light setup than a two light setup. We would place two lights on each side and one on the back with the back lighting being cranked up to turn the background into pure white. An alternative is to have a very high powered strobe firing in from the top of the lightbox with a translucent reflector diffusing the light.
Their tutorial on making your own DIY light tent is after the jump.
