rendering...

Is there a simple answer to why the on-screen preview - even at high quality
- looks "acceptable", but when I render to a TIF, I get a washed out image -
like I am looking through heavy fog...?

(rendered output - TIF file)

(rendered output - Full Screen)

I really do hate Pro/Render. It seems to defy the definition of insanity...

(insanity: keep doing the same thing and expect different results...)
(pro/render : keep doing the same thing and get different results...)

Sorry for the mini rant. Thanks for reading.

Nate,
Rendering, you got to love it. The simple answer is No.

What you see is fairly common amongst many renderers. Preview rendering
is just that, a quick shot of what the colors/image may look like, where
the lighting falls and where the camera is pointing. Not to mention
texture map appearance, bump mapping, hdr alignment, etc....

For most good renders expect to tweak until the output is right or until
you get sick of tweaking. Do a test render with lower quality settings
and at a smaller resolution until the light, color, camera, etc are what
you like and then crank them up to full. Your sanity will appreciate
you for it.

Looking at the images, it looks like it can be corrected by changing the
gamma values. This can be done in an image editor. Also, just for the
heck of it, I did a search in the options dialog for "gamma" and found
an entry:

window_gamma Gamma correction to apply to images created by renderer.
Default value is 1.0.

Try it.

Isn't that the very nature/definition of rendering?

I agree that you should look into the gamma correction.... Another
suggestion, if you like the result from the render to screen.... simply
do a print screen and capture it. I have done this in the past as well.
