Contrast Rejection Help

Wed Jan 31, 2007 10:05 pm

I've had a batch of rejections citing the reason as "contrast"

This one I can see as being valid

and possibly this one

but this one I think looks OK.

Any thoughts? I'm not sure how this could be improved in terms of contrast. Sunny day, static subject, lots of time - what could possibly go wrong.  Smile

This one, taken minutes later and used the same processing, was accepted.

Hi Derek,

They all have this 'milky' look to it when you have too little contrast (and the whites are not white enough), so I would say correctly rejected. BTW, I think you were lucky with your accepted shot, not that it is a bad shot, but certainly looks better with a kick more contrast  Wink !
Just sit back, relax and have a glass of Merlot...enjoy your life!

In the last one I can see that white is too bright...
A suggestion : learn to take several photos of the same subject because sometimes light conditions may vary from angle to angle. In this sense you can work on more shots and have more chances to get one accepted if another was rejected.

Thanks for the comments. Didn't have many contrast rejections before so I thought that part of the post-processing was fine. Still don't see it myself but you live and learn I guess.

Wouldn't that be an exposure rejection rather than contrast? (even though the histogram is right in the middle)
Whatever.......
