I have found that the sweetspot with my current set-up is to have the subjects 5"-6" from the camera, which I mount on a small tripod. Three lamps aimed at the top and sides of the lightbox provide plenty of indirect light, while a ten-second delay on the shutter prevents camera shake. Nice, bright, and sharp raw photos result, which I then crop, adjust colorcast, and sharpen with Photoshop Elements 9. Knowing that I can now zoom in even more on the figures helps too. Maybe not quite professional grade pictures, but much, much better quality photographs than what I have posted for quite a few years here on the GD of S blog, which, amazingly, is approaching its eight anniversary in late August.
Finally, and in reply to a few recent queries, yes indeed. I have a solo game planned for the week of Springbreak in March. It will be based on a historical battle from another period, so you'll have to guess which one when that gets started next month. That's all I'll say for now though. All right. I've got to do some real work now.
