Re: "Lossless Compression" creates artifacts in A7r
Few things come to mind for me on this ...
1) 8X or 11X viewing ... I appreciate the scrutiny of microscopy (applaud the effort, I think) as much as the next guy, but I wouldn\'t kick Marilyn Monroe off the set for having a freckle smaller than a mustard seed between her toes.
2) Does Sony have OEM native software for processing rather than relying on Adobe\'s algorithm\'s?
3) The profile differences between sRGB, aRGB and ProPhotoRGB progressively \"stretch/push\" things farther mathematically with bigger \"steps\" for a given input value ... the more you push, the more artifacts you are prone to.
4) If you haven\'t been processing non-AA filtered images, and think you should process them the same as AA filtered images ... you\'re going to have a tendency to be over processing if you use the same approach without first learning the diffs. Learning to process Sony\'s Lossy/Lossless/ files might have a learning curve to them that don\'t follow the same paradigm as before.
When I switched to Canon files ... new learning curve, picked up my SLR/C ... new learning curve @ A7R not unreasonable to anticipate a new learning curve for dealing with lossy/lossless/ files.
That being said ... I like my RAW\'s to be uncooked and if Sony is taking some liberties, I appreciate being made aware of those liberties. Whether or not they make significant diff or are a \"smart\" practicality will be highly debatable for some. I\'d like to take a stab at the RAW but don\'t feel much like working a 36MP file atm. Maybe a couple manageable crop sections of the raw would be appreciated to play with.
There seems to be some \"yea\", some \"nay\" at the orange peel (here and elsewhere). I\'m inclined to think that this will be realized as relegated to algorithm, processing, profile approaches and a need for some old dogs to learn a new trick (or two).
Worth keeping an eye to as we continue to learn more about the A7R ... which raises the question @ did we ever confirm the A7R no-AA filter as truly non-existent, or is it similar to the D800E approach?
Now, where was that freckle again ... or were you too busy looking elsewhere to notice?

files might have a learning curve to them that don\'t follow the same paradigm as before.
