When doing photo composite, it is necessary to make the figures less sharp with most photos, while also making the photo more sharp if possible.

Here are the render settings I used in the last image. Make a render of your own, then change to these settings, and render again. Study the differences, if any.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
