Hey Y'all: I have a project created in Ldraw/POV-Ray of which I would like to create a higher (PPI/DPI) resolution image of approximately 8" x 8". I'd like to be able to achieve something like 600-1200 ppi for the final image printed on paper. I have used Photoshop for mocking up my final designs and it has a tendency to default to 72 ppi. It can be arbitrarily set to a higher resolution, but if the original image's resolution isn't likewise higher you just end up with a blurry, more ppi heavy image. I hope I am making myself understood...(?) I have the funny feeling that what I need to know is some arcane POV-Ray thing that would up the ppi of the images outputted from POV-Ray. Anyway, that would be one solution. Anyway, I'd be grateful for any help in creating images with higher ppi. -- Hop-Frog

You need to create an image in POV-Ray that's at least 4800 x 4800 pixels. You can't/don't need to set the ppi in POV-ray. Then make sure your image program prints it at 600 dpi (do _not_ resample the image). You're weren't asking how to create (...)

What kind of extraordinary printer do you have ??? Even with good inkjet photo printers (with so called 1440 dpi resolution, which is actually dot placement resolution), you can't see improvements above 200 dpi... To be conservative, your image (...)
