It varies by agency.  Shutterstock doesn't have a problem with it; I've submitted over a hundred images from a single model shoot and had them all accepted.  Dreamstime's the opposite; they consider more than a few shots with the same model too similar and will reject . out them.  Most other agencies are okay with sets, some more and some less.

Thanks for these comments and tips, their very useful.

I suppose one of the reasons to reject similar photos is to decrease the 'clutter' and boost the amount of variety in search results.

I might agree with that in certain way but DT is going very far on this matter.. they want a picture of a subject or a bunch into a set.. thats isnt going to help stock and also our pockets

Rather than submitting multiple files, perhaps joining the shots into one image document could be more effective?

The downside is of course the decrease in each shot's image resolution. You are sharing the max 8k with 4 subject shots giving each shot about only 2k each. If you wanted each of the 4 shots to have a 4k resolution the image document would come to a killer 16k which would probably bust the downloader's ram when opened.

Can you go beyond an 8k upload with Shutterstock?

k = thousand. The max height or width is the 'k' in resolution. So, 1024x768 = 1k, 2048x1536 = 2k, 4096x2160 = 4k, for example.

This kind of language is used more with people in cgi. Yes, it is pretty much generalising aspect ratios.

8000 x 6000 = 48000000 = 48MP

8k = 48MP

I guess you haven´t read my comment

The problem of DT is that you can have 1 or 2 pictures that they will think are SIMILAR.. if you try to upload a 3rd one they will rejected (unless you are a DT honey, which there are tons of them..) that´s why if we want to have different angles and such we need to create this collages which like said here are paying us 35 cents for a 40 megapixels or more, imagine stock in 1 or 2 years?? designers will look only into this "big" pictures and we will be working for 5 cents instead of 35 cents per REAL photo.. thats going to screw stock but again agencies (mainly DT) is asking this to contributors, if we are doing them, we are accepting it.. but again?? what can we do?? leave one of the big 5 ??

No. They urge us to do this, they don't force us to.  Let them take one and reject the rest if that is what they want to do

I suppose it is possible a collage might sell more quickly, move up levels and make more money in their system than a set of individual pictures would. But I'm not convinced and the subscription option undermines that idea.

If you put up collages with material that might go insane then you have the risk of it getting loads of subs sales and you can't take it down for six months if you feel it isn't working for you.

I might try something, sometime to see what happens.

But surely the thumbnails of any collages would look completely useless, undermining any sales potential they had?

DT is weird, they must have somekind of different types of reviews for different contributors.. so I would say upload all the 10 and wait to see how it goes..

This makes perfect sense to me, and I don't understand why it's not common practice among the sites.  As a video producer, I've had occasion wherein I want several photographs of the same subject with only slight differences to create a rapid montage video.  I might give each photo a fraction of a second, so if I want a three-second clip, I might use a dozen different photos; perhaps even more.  I wouldn't be able to shop on DT because of their policy of rejecting more than two or three shots of the same subject for being too similar.  I've had photos rejected at SS for the same reason, and my experience has been that all of the sites do it to some extent.  It doesn't make sense to me, but the image-stacking idea certainly does.  We might offer special pricing for purchasing the entire stack, but hell, we're already working for peanuts.   

Ah, so it's the old "megapixels" language.
