I recently started playing around with some panorama shots.
I was wondering how will it go on stock sites...

Does anyone upload panoramas to stock?
What sites accept them?
Do they sell?

I've found most sites accept them if they're done well enough (i.e. no obvious joins or differences between the individual photographs).

I've sold a few, including one to a local magazine, but they're a rather specialised area. Most people seem to want them as banners across the top/bottom of pages, and there isn't so much of a market for that.

Hi
Yes a got a few  the market is not to big.

I did some boston skyline ones, almost all the sites took them and are selling well on at least two of the sites

Do what you love, who cares if it sells!

I have few cloudscapes  and some interior shoots made with PT gui pro
cool softvare for making panoramic images, also u can changes of view + best thing
makes fine feathe blend with different exposure.
Much better than you got from Canon Photostich software.
Dont know for Nikon
