color loss in hdr

I’m having a problem with color loss after hdr processing. I’m starting with RAW files, using Photomatix and Photoshop, and all color space is set to AdobeRGB. Everything is great until I try to open the finished JPEG with anything other than Photoshop. The colors appear drained and washed out. Not a problem for printing or using on my computer, but when I submit them to microstock sites, the colors are very muted. Any help would be appreciated.

Most websites are not set up to post AdobeRGB. It will look good on your monitor. And when you print. But not anywhere else. So I have read.

Thanks!

Set your colour space to Srgb. The Adobe rgb gamut is too large for monitors to reproduce.
