I'm hoping someone out there can help me. I want to blow this image up to approximately 7" x 10", but when I do just using the standard image viewer that comes with windows (not any of the media players), I get jaggies. Does anyone know how to get rid of these? Do I need to render the image at a higher resolution? Any help is appreciated. Thanks so much.

Yes, you must render at higher resolution to get the best clarity. That would be 504 X 720pixels at 72dpi if i figure correctly. I think you'd be able to get away with rendering at 435 X 648 and then blowing it up to 504 X 720.

After a few trys, this is as good as I can get it, keep in mind this is also a JPG. format. IM me and I'll e-mail you a bmp. which is a bit sharper if you want.

I'll try the re-render first. I just bought a faster machine so this will give me a good idea of how much faster is can render. Thanks for the help!!!!

Since you're going to re-render, here's some numbers for you: To print the image 7"x10" on an inkjet printer, your render should be no smaller than 150 ppi so that's 1050 x 1500 pixels. For best quality on a printing press, you need 300 ppi (2100 x 3000 pixels)

I was under the impression all you had was the image. If you have the Rendering sofware you may want to pick up some decent image editing software-VS-the default windows viewer. Good Luck

Yeah, I'm with JohnPenn on the render size. Any good inkjet should be able to put out 150DPI, which is pretty near photo quality for non-professional purposes. To keep the detail level high, and to keep the image looking how you had intended, don't resize an image with any viewer or program. Just render it higher, any resizing will create artifacts and blur the overall detail. Of course, if you WANT to blur the details, go for it! Don't let us stop ya.... (grins)

This is a pure Bryce render. It started life as the default image size in Bryce. I re-rendered it at Premium Quality with 144 rays per pixel. When I tried 256 rays per pixel, my 'puter choked. The serious video card I am installing tomorrow will hopefully take care of that. For 2100 x 3000 pixels - What overall finished size are we tallking about - 7" x 10"? Thanks again!!!

To get the pixels from inches, multiply by the DPI - dots per inch. Therefore, 10" at 300dpi (pro mag quality) is 3000 pixels, as mentioned above. Divide to go the other way. So 2100 pixels is either 7" (300dpi) or 14" (150dpi). Also, unless you're rendering for 300dpi, or you're using very detailed volumetrics or cross hatching, or possibly severe DOF - you never need to go above 64 rays/pixel. For the above image, I doubt you'd need to go above 16. I'm doing a piece at the moment on 9 rays/pixel, with massive amount of volumetric cloud, and it's looking fine. In fact, when it's done I'll probably smooth it because it's looking a bit too sharp.
