I’m trying to improve my miniature picture-taking skills. Here’s a pic of a Games Workshop River Troll done with the mini inside a light-box.
The light-box is just a cardboard box with three sides mostly cut out, creating windows in each side, and then white tissue paper taped over those windows. You cut a rectangular strip of posterboard (in this case I used white) and curve it inside the box to provide a background. The lights go outside the box, the tissue reflects the light around inside the box. You stick the mini in, snap the pic. I think it’s an improvement!
Here’s one for sale on Amazon: link. My home-made one cost about five dollars for the white tissue paper (gift wrapping tissue) and a couple bucks for the posterboard.
