Hunter, I'm using my tablet with selective natural light. It hasn't been easy. But I learned a few tricks on a couple other threads.
I use a larger size, but medium depth tupperware bowl to balance my 10" tablet. Find the sweet spot so that the snap of the photo is already counter balanced when I click. Depending on your light, take the pic with a white background first. If focusing becomes an issue, switch up to the black background.
The key is the lighting. A cheap led desk lamp with no background lighting works well too. Hope it helps!
