I think that if you do enough preworking, like setting up your scene right, getting or making the right shaders and setting up a good lightingsystem, applying the right rendersetting, you don't need postworking.

Bopper.

i personally disagree.  photos don't appear raw in magazines, even after professionals do incredible things in the studio.  commercial photography generally involves a lot of Photoshop (hence the name).  and not just changing levels or curves.  a colleague once mentioned to me that he was some how involved with advertisements in Popular Mechanics, and they apparently heavily postwork highlights and other phenomena on tools. 

i generally do tons of test renders, and try to get my lights, materials, pose, etc. as good as i can.  then i use photoshop to improve them. because i can.  and since i can, why would i settle for less and stop at the render? 

imho, usually significant postwork is easy to spot.  even when i was starting out, i didn't find it that difficult in general. photo composites tend to show their lie in the eyes, hands, feet and sometimes joints.  frankly, as long as people who render with C4D, Vray, Maxwell, Mentalray and other high end renderers are posting under Poser, i think the postwork issue is moot.  there's lots of images in the Poser gallery with no postwork at all that still can't be done in Poser. and if the artist doesn't say anything in the description,  you just have to be able to spot the rendering engine.  thing is, i don't think Vicky  pics are welcome in those galleries, so i don't blame the artists for not wanting to garner lots of comments that basically put them down for not creating their own model or (sometimes) texture.
