My workflow:
1. Stitch pano in Ptgui
2. Convert pano to .tif cube faces
3. Open bottom cube face in Photoshop to plug/retouch the bottom.
4. Save retouched bottom cube as .tif
Now, if I drag all 6 cubes to the 'cube to sphere' droplet, it creates a panorama, but the bottom cubes color has shifted. (only the bottom cube)
I have the same issue if I use .jpg's
What is going on???
The only work-around I have found is if I open all 6 cubes in photoshop and then save them all -- but then the entire pano has slightly muted colors.
