egads, I submitted the preview for the 4400x2500 pixel version it asked for on the page, downsized to 800x455 to be proportional and stay under that 800x600 suggested size. I am really bummed because Poser wouldn't render over 4090 pixels in any direction and I had to do all post processing on an upsampled from 4090 to 4400 width image. No way to get those dimensions now without cropping some of the original image out. It wasn't that I couldn't lose some pixels in it anyway but the overall image won't look the same - might be better though, that was a very odd shape to have to fill, especially when Poser couldn't handle a lot of characters and props and render that large. I knew it would print long and narrow, I thought they were going to do some caption or artist story under the images and print at 400dpi from the way it looked when I test printed the image. I don't know what to do now, that image wasn't great, but it could have been better if I didn't have to choke Poser trying to render it so much larger than it needed to be and could have kept to a standard landscape dimension. It being so large made me back off on more props and details in the image to keep Poser from choking which it did twice when I tried to add just one more thing. what to do what to do...
