Chas, rendering at 300 dpi or 600 dpi doesn't make any difference at all. Only the pixel size counts. DPI is just a number that sits in the file and can be changed in most any image editor. The reason for differences in how you save an image has to do with Poser inverting the alpha channel sometimes. The image itself is not affected. I do something weird when I save images after I've rendered to a new window. Because Poser has focus problems sometimes, I'm never sure exactly which image it will save so I click the rendered window closed (yep..don't faint) Then Poser asks if I want to save first and I click the save button on the dialog. Heh. Thanks for all the super info, Lyrra! Makes me want to try it!
