Using a lightbox diffuses the incoming light, which helps eliminate glare and bad shadowing.I made a new lightbox recently as my old one was too small for group shots and big figures. I used my old terrain box, which is a folding cardboard box with a lid, and the perspex from my original lightbox.
folded back together, added some duct tape hinges to the lid...Alll done!
I am not getting enough light bounced off the inside of the lid, so I will add some crumpled tinfoil to try to fix this. Sadly, I'm fresh out at the moment.
If you are not happy with your mini photos, why not give something like this a try? It's a lot cheaper than a commercial light-ltent and does exactly the same job in 1/2 the space.
