As noted, there is an area of OOF clipped highlight on the side of the nose. Anything above 100% is interpolation anyway, that is not necessarily part of the actual image. At 100% you are looking at the equivalent of a large enlargement with your nosed pressed against it too, as you know. I think that perhaps you might find all sorts of seemingly odd effects if you were to look as closely at many, many images. George provided very valid insights too regarding highlight recovery. I'd add to that that ACR is purportedly better at that function than other Raw converters. If there is any information in any of the 3 channels it uses that in an attempt to restore the 'clipping'. It will display true clipping as 255, 255,255 not substitute grey for those pixels. Further, as George mentioned, unless the white balance is perfectly neutral (unlikely and not always desirable anyway) you may observe some colour tone in that type of area. All of that is getting into many other variables anyway, including your monitor, the agencies' monitors etc etc. Really that sort of refinement is in the area of fine art, well beyond any reasonable expectation for stock agencies. If you wanted to be systematic investigating this you might need to start from the Raw file firstly. Me, I bet it is not even questioned or noticed by anyone. Probably you need to stop staring at your screen for a while, your brain would be performing all sorts of 'post processing' depending on what tones and colours you have been peering at. I hope you sell a gazillion stock shots. Cheers Geoff http://www.pbase.com/hoppyman/e http://gallery.leica-users.org/v/gh/ -----Original Message----- Subject: Re: [Leica] Question - Artifacts?

I guess if it doesn't show up at 100%, I don't really need to worry about it. Thanks - Tina _______________________________________________ Leica Users Group.
