Thanks for this really interesting comparison. I am impressed by the roc/gem technology, especially by this example of gem (grain reduction). Of course we expected some grain reduction anyway because of the 4000dpi (which I think the LS4000 scans at even at the lower resolutions that were used in the examples) and indeed there is some improvement without GEM. But gem as well makes this very grainy film look good! It is hard to tell from this example how much softening there is - I can see some apparent softening but this may be fixable with different settings or a bit of sharpening. ROC - colour reconstruction - has changed the image a lot. My guess is that the original was daylight film with tungsten light in which case ROC has done an arguably good job. Now too cool, but I am sure I would find it easier to adjust for good skin tones from the ROC'd version than the original.
