after editing a raw photo, then save as to Photoshop cc, the file extension is xmp with the big blue Ps icon over the picture. I can not open up the picture to review it or to do more editing in any program . Can you help me?
Like JE and JT said, the .xmp file is not the image. It is what is known as a side car file to the raw file. It contains setting used by Adobe Camera Raw. If you want to bring the image into PS CC you must open the raw file. When you have opened in Adobe Camera Raw you can open into PS from the raw module. Or while in ACR you can save as a tif file and open that in PS.
