Personally, I upload only one image in color. The buyer can simply convert to black and white if they so desire.  Some companies might consider it spamming if you upload both images...

Most designers prefer to add their own post processing effects to match their project exactly. Not all black and white conversions are created equally. Doing it yourself limits the options available to the customer and ultimately limits your customer base. In my opinion you are better off uploading the clean, color version of the file and letting the buyer adjust how they want.

Adobe Stock will accept some black and white content but it must have a serious "WOW!" effect to be considered.

When I see that Fotolia rejects a vertical image of a subject already submitted in horizontal format, as "similar image already submitted" I have serious doubts that the Fotolia really understand the designers needs, and/or the process of projecting a layout for a catalog or a magazine�

I confirm to have the same kind of experience. But not a lot on Fotolia (probably because they have the idea that red tomatoes isolated on white sell better, and they accept them easier than a good b/w image�)

I would like to state for the record that we will also accept photos of tomatoes that are not isolated on white.

I would also like to mention that my comments above were simply my opinion. We will accept some black and white content but as a contributor you should ensure that black and white provides the best value for customers. Many contributors confuse what works well as fine art with what works well as stock. I'm not saying you are personally, but a more general statement. Do what works best for you of course.

Out of interest do people upload black and white images to stock sites? I presume its not done. I often do black and white for portarits as attached. I guess one could always upload two copies.

I have a number of photos of fruit bats hanging from trees which have severe chromatic aberration. It's so prominent that you don't even need to zoom in to see the colour fringing. They weren't shot with a cheapie lens (though it was a zoom and the subjects were against a bright background.) I couldn't get rid of the colour fringing in Lightroom, only reduce it a little. With the amount of CA that these images have, I doubt many stock agencies would accept them. Though I was thinking of converting them to B & W and trying my luck.
