I have downloaded and am trying out both the Digital ROC and Digital SHO, specially after reading things on this list. I am very impressed with the ROC. I am having a problem when trying to apply the SHO to the same image, though: On trying to apply it to a 31 MB file, the message comes up: Internal Error. Image max is <= image min and no window opens up, nothing is applied (though the history shows it as if applied).I am using Photoshop 6 on XP. Anyone any ideas?
