I have been working on using the many suggestions you all have given me for improving my latest image, but I ran into this problem with Depth of field. As you can see from the picture, the background is very grainy. Here are the relevant camera and render settings: Blur = 1% Render quality = Ultra Antialiasing option sliders: Minimum # of subrays per pixel = 16 Quality Threshold = Best (all the way over) Is there a way to fix this. Right now, my render time was 51 Minutes for just this little blurb that you're looking at. My full image is to be rendered at 6000 X 4800, so I'm sure the render time will be over 24 hours. I honestly can't see commiting that much time to a render if its going to turn out so grainy. Please help! Sincerely, Tony
