Yes there is a pluggin called photoshop
If you use the editing selection tool, you can right click the image and touch-up image in photoshop. Note that some images are split into several tiles, these are much more difficult to edit with consistent results, but if you touch them up using photoshop with eg curves, when you edit the next tile you need to hold down alt/option when you choose the same adjustment and it will used the settings you last used .
