Re: Help with blown skies


Here's another experiment: using the Adobe Color profile, we try to recover detail from an apparently over-exposed sky.





The first image shows the Adobe Profile. Note the histogram: the high values fit within the tonal scale, but just barely.

The second image shows the Linear Profile: there is "wiggle room" at the high end of the tonal scale.

The third image shows what happens if we try to rescue details in the sky from the Adobe Color version. The result is flat gray.

Comment: Perhaps the Adobe Color profile is automatically expanding the tones outwards, to fit the extremes. The result is that the sky, which actually contains color and texture, is blown out to white. The details in the sky cannot be recovered. They have been discarded.

Please correct me if I have overlooked something.
