Again, there are many images i've seen, that are just begging for a little postwork.  Even if its simply to correct levels, gamma, and color correction.  I do find it odd that there are some render purists who balk at the very idea...... but even professional photographers do this, its called retouching.

Wether you spent 6 hours or 6 minutes on a poser render, its no different than a photographer (the means and work are different i grant you) who took 6 hours to set up or 6 minutes..... if the finished product has flaws, its flawed........ don't argue with the viewers eyes for pointing them out.

Simply stated, would you pay for a packet of school photos of your children, or a package of wedding photos or a friend's snapshot...... (not bought for that one fo course) and want it say, hanging on your wall to look at, if there's a big unpelasant streak of light across it, red blaring eyeballs, or it was washed out and overexposed?  No?   I sure wouldn't.   I would tell them to have them adjusted, retaken or retouched.  Wouldn't you?

So in the same stroke, when I see an otherwise beautiful render and think....."wow... the crease in the armpit looks like a crater".....  thats what viewers see, they do not tell themselves "Gee, poser sucks with the joints".

The basic problem is, we might use all kinds of electronically microchipped wonders to create things to look at, but inevitably, we are viewing them with HUMAN EYEBALLS.  Poser, though making great leaps and strides in its capabilities, it is what it is.  Though some can and have made splending perfect renders, it has some astronomical faults........ we don't have all day, so I wont list them all, but I'll add in the example of the general figures used tends to be the problem.

The new to average user will come across these problems, such as "bent crinkle hair", creased crackle joints, rubber band shoulders, lighting issues, unwanted shadows, or ill placed shadows, and my personal favorite "blank eyed undepthful gazes with no shadow under the upper eyelid".

Without clever and talented postwork there, all that hard work can be overlooked with a general consensus of "ugh".  Our eyes are made to see whats just not right in front of them.  There is a difference between a perception, such as expecting a viking to have a horned hat and the image doesn't, and FLAWS.......  we are going to notice, judge, and turn away from that which is:

Too simillar to the last thing we saw (i.e. canned anything, same hair, clothes, figure, pose)
Obvious physical fault (wrong bent limbs, plastic skin, unnatural body movement and so on)
Wrong, too bright, too dark, or incorrect lighting
Too strong or too weak gamma/brightness/contrast

I think the new word of the day should be "retouching" for those that correct problems with renders .... its what the pros do to make a visually appealing image.
