Here we call it a grundey, I think it sounds better than wegie.

Sent your rendering through Paint Shop Pro 7's automatic contrast
adjustment. I thought the results were a significant improvement. The
added contrast brings out the details in the picture.

Aww Damn... You beat me too the punch:-) I did the same thing, only in
Photoshop, in my opinion Photoshop does a better job.

Specular is turned on, but my textures are all messed up and need reworking.
My 'dirt' looks nothing like dirt.. too smooth (on the block base)

That's supposed to be scratches on the surface.. just a scaled normal.

Yes.. good point. I have lost the example code for blurred textures that was
posted recently. I'll try and locate it.
All the best,

I find that all povray output benefits from that one filter. are we all
doing something wrong, or is povray the maker of washed out images.....

Minor hue variations in texture/environment/lights would enhance
the image, unless it's supposed to be b&w :) I would try LDRI
lighting. Like in this one: http://www.pp.htv.fi/kkivisal/bolt_nut.gif
Texture is mostly reflective averaged bumps dents normal.
Actually just wrapped this image around a sphere and used
area light. Works well with MegaPOV blurred reflection
and provides some variation in lighting when used with radiosity
and not so reflective objects.

Oh... :o) Your image already looks better than brazil's! The bolts look
more realistic in your version! The ground does not.. The postprocessing by
Skip Talbert and Thomas Lake are an improvement too, but should be done
internally in Pov for greatest usefulness.
The shadows in brazil's version are too dark...
Looking forward to see your next bolt version!
Regards,
Hugo

I agree. What kind of control do you have over that feature in Photoshop?
PSP's control lets you control the bias, strength, and appearance but only
as a few simple radio button options.
