I have a hit & miss relationship with isolations at iStock.  Most of the time, the same files will be accepted at Shutterstock, Fotolia or <<insert other agency here>>.   I haven't been bothering with resubmitting because the inspectors have not been including clips to indicate where the issue is. 

I would greatly appreciate it if someone who has a lot of accepted isolations for iStock could maybe help me figure out specifically what my issue is.  Sometimes they accept one that I'm sure is going to be rejected, so the rejections are not clear cut to me.

My port is half the size at istock compared to elsewhere and I have a stunning 41.86% acceptance rate.

I don't have a lot of isolations on istock (they are too much hassle to do, so I don't bother). but I've never had any rejected. I do them as much as possible with lighting, then use a combination of a channel mask and the pen tool to create a mask to isolate the object and use levels to whiten the background. I generally only isolate objects with a very deep depth of field, otherwise geting an edge of the degree of fuzziness consistent with the segree of focus is too hard - unless the isolation can entirely be done with lighting. And I usually leave shadows, so it's not really a real isolation anyway!

Almost all of my submissions are isolated. I downloaded your Hardhat photo and found that you have stray pixels along the edge.

Here's how you find them. Create an Adjustment Layer and choose Threshold. Set Threshold all the way to black. You will see stray pixels floating away from the edge. Paint them white on the image Layer.

Thank you.  I will post a person isolation when I get home...after trying the threshold trick on them. :-)

I've done the levels and moving the midpoint to find any stray areas in the background, but apparently it doesn't catch everything.

I am curious about this method for checking for stray areas, as I have this rejection reason from time to time, especially before I purchased CS3.  I used the threshold method to check on one of my isolations where I used the pen tool and refined the edge, the used it as a mask to make the isolation.  Using a threshold layer to check, I see some black "flecks" that are right on the edge.  Are these "flecks" from the edge refeinement?  Istock accepted the image that I checked using your method.  Do you suggest looking for large areas like in the hardhat example?

I think the stray area's can be seen better in this image using the method from the link I posted earlier.
