In DS 4 it is rendering my images at 96dpi I believe. And that is with the render quality at the highest level next to the turtle symbol for slow.

But if I have only one subject, say V4 and nothing else but a photo background I'm supplying and I want good, soft, natural looking wraparound light(mesh light?) and don't know yet if I would need more than 1 mesh light, and I want to render @ say 16x24 inches as mentioned earlier, what do you think I'm likely to need?

For props, the only thing would be her wedding ring(always) and maybe simple clothing. I guess the only large prop I have would be the Ultimate Bed by Powerage(available here). And I don't use that all the time.

Also, I would only be doing one render test at a time.
