hallo klaus,
when using the "sphere2cube" droplet (working mainly on macs) and additionally "make multires" it always generates a very strong colormasked preview file (and only the preview!) of the same color cast - like here .
I tried different workflows. My basic file comes from autopano pro and is then prepared with photoshop. It is then always transformed to sRGB color space. I always work with 8 bit colordepth. There is no difference if the file is saved as jpg or tif (tried lzw, zip, IBM, Mac...) or if saved with or without including the sRGB colorprofile.
Do you have a any suggestions to this? - thank you!
