Subject: Rendering at Double Size Benefit - Myth or Reality?


Zarabanda ( ) posted Mon, 09 February 2004 at 5:21 AM · edited Sun, 22 September 2024 at 4:27 AM

I've heard a number of times that rendering at double the size of a final image and then reducing the image size by half in Photoshop will yield superior results to simply rendering at the final intended output. Can anyone prove this? I rendered an image twice, one at 800x800 and the other at 1600x1600, then reduced the 1600x1600 image to 800x800. A side by side comparison showed identical images. I'm only interested in onscreen picture quality, this has nothing to do with printing.

For on screen picture quality, at the default 72 DPI, the answer is no. You might pull a bit more "detail" at as high as 96 dpi, but beyond that, ferget it. No monitor has the technical capability of displaying it better.

I find that Poser 4's anti-aliasing is less than perfect - so I do this as a way of filtering it. This assumes your resize routine resamples the image and doesn't just drop pixels.

Zarabanda, Yes that works becuse poser anti-aliases everything to death. Another way is to sharpen your render in Photoshop and then fade by 50%. It is alway best to render larger and then reduce. Twice as large is not really neccesary. It depends on your scene window. This is my setup in Poser. So I do get pretty large output. I scaled it down to 800 wide from 1034 for posting purposes.

looks at Anton's UI Is that Poser 5? If so, how did you customize the UI like that? -=LovePyrs=-

looks like poser4 - you can customize the desktop - just drag and move all elements to the desired position ...

The double size render is more for the postwork. I double and render a 300 dpi. Once I'm done my postwork, I reduce it to 72dpi.

Yes, poser does tend to over-antialias. I render about 30% larger than the end result I want, do my postwork at the larger res. then (usually) add a sharpen filter before resizing. Sometimes this needs a little more postwork at the final resolution. Depends on the effect I'm looking for.

How do you get the Tools and Doc Style menus to go vertical?


EnglishBob ( ) posted Mon, 09 February 2004 at 8:45 AM

Alt-click on the title. :)

I render at 2 to 4 times the size and turn anti-aliasing OFF. It speeds up render times by as much as 75%. SInce I work mainly for print, having a sharp edge like that makes for easy wand selection, without the halos.

well rendering a larger picture helps if you need to do some minor postworks to fix some flaws.. then resizing the thign down will let your correction far less visible


rreynolds ( ) posted Mon, 09 February 2004 at 11:39 AM

Actually, rendering at a larger size and reducing just adds a bit of blur to an image. It's not extremely noticeable in a side-by-side comparison, but hair and other details will be softened. Shrinking an image eliminates pixels of detail and requires the software, doing the reducing, to decide which pixels to toss. It's usually worthwhile to take any Poser image and bring it into Photoshop, or other image software, to enhance colors and contrast.

And now I see with eye serene The very pulse of the machine. William Wordsworth Incidently, dpi has no meaning in a render, it relates to printing on paper.

Anton, that sims tex looks awesome. makes me wanna dust off my copy. :) I use bicubic resampling by default, so I guess I'm good in that department. I can definitely see the advantage of working big in postwork and then reducing size. ::must hide all traces of cloning tool...

With FireFly, you don't need to render at double the size. You can adjust antialiasing to your likings using the post filter, filter size and pixel samples parameters.
