Sue, I guarantee you that ss is much nicer to work with than what you are used to.
also rejection wise, we get minority reports here, and we dont see many of the pictures so nobody can judge and everybody can have their say.
Again show us the pictures, else such a thread is meaningless.

From a vector person's POV, I think you guys are beating yourselves up and second-guessing yourselves for no reason. Honestly, when an entire batch of my illustration jpgs are rejected for some ridiculous reason like "noise" while the vectors are accepted, it's clear to me the photo inspectors (or a few photo inspectors) are off their rockers. Either that or there's some incentive we don't know about for them to make mass rejections.

right - that's much closer to  the probable reason, and that's why seeing the actual rejects is irrelevant when the same images are accepted elsewhere or as similar by SS - the problem is with reviewers, not the content -- I submit my shoots spread over several batches -- every so often, mostly weekends, an entire batch gets rejected (right now usually for lighting or composition), while the next batch, with similar images, gets accepted;  so for me, overall, it's annoying, but some of the shoot eventually gets accepted. 

since we can't predict which images will get rejected, it becomes necessary to submit more similars than normally, since I don't re-submit without making changes

I've completely quit and have no plan to resume any time soon.  Just not worth the aggravation anymore.   Especially since every "exciting new opportunity" from here on out will be 35  cents, like the FB deal.   Deal me out.

I do my own illustrations and I submit for a photographer. Some person(s) on SS review team is going nuts with the reject button the past few weeks. Their comments are totally unhelpful�and in some cases totally ridiculous. It's part of the regular ebb and flow of subjective judgements. Make sure your pix are sharp, logos cleaned up and releases are correct. Maybe make some changes and resubmit. Also submit to other agencies. SS is not the only one that will make you money.

The last 2 weeks in SS  I have had ALL images rejected for same reasons-POOR lighting, INCORRECT white balance, POOR composition- and I am utterly at a loss after spending HOURS in RAW Bridge and PS ! What is the problem? I am thinking of not submitting any more.
PS-similar images accepted in recent past.Is it a BOT or WHAT???
