I know, it's a boring question. I need to supply artwork at 300 DPI and I'm not sure what that means. I usually export my rendered image as a BMP, fiddle in PSP and then save as JPG with minimal compression (say, 3). How do I know what the DPI on such an image is?

Go to render options and change the dpi. It should come into photoshop or psp at that dpi when you go to post.

PSP will enable you to specify the dpi on your image - it'll be somewhere in the options (not in reach of a copy at the moment, sorry). I think Poser has the option to specify dpi also, somewhere in the render options. If you do this, subsequent post work should preserve it. It's a nominal figure which has no bearing on the actual image, but professional printers seem to want it. They will also probably prefer TIFF or maybe PSD format images rather than JPEG - you should check that also.

Crasher - an appropriate name. We collided, sorry. :)

EnglishBob: It has meaning if you specify the size in physical units 6" by 4" at 72 PPI is very different from 6" by 4" at 300 PPI. Nontroppo - the people to whom you are supplying the artwork should have given you a physical size and a resolution OR a size in pixels - resolution alone just isn't useful. And if they are serious they will need an uncompressed, or losslessly compressed, format - TIFF or PSD, or EPS or PDF perhaps.

As the above mentions but doesn't outright say... Set the resolution of the render within Poser, never try to increase the resolution with Photoshop or Paint shop, you quality is a total loss. The height/width will scal together, so ya have to make sure you document window size is set right to begin with as well. :) Hope this helps ~ Rich
