When I'm rendering an image in DS4 alone,(no Reality or LuxRender yet) with the render "Quality vs Speed" settings slider in the upper left corner with the Worst(Hare) at 1 and Best (Tortoise)at 4, I've got it set at 4(Best). I'm also using render quality settings under3Delight that one of the experienced DAZ users recommended and all that does produce an excellent image.

Now here's where the 96 ppi comes in. In Photoshop under Image>Image Size>Document Size>Resolution the rendered images are 96 pixels per inch or 37.795 pixels per centimeter.

When I asked someone in the DAZ forums on their site about how to change the ppi to something else like 300 or 360 which I'm familiar with in photography, he said that ppi doesn't really matter & you can change it to whatever you want later.

So apparently 96 ppi is the default setting in DS4 which cannot be adjusted until after rendering in a PS type image editor.
