Advertisement Posted November 25, 2009 Posted November 25, 2009 Hi john bartlett, Take a look here Artefacts Lightroom / magenta highlight cast. I'm sure you'll find what you were looking for!
Guest WPalank Posted November 25, 2009 Share #2 Posted November 25, 2009 Your computer is a Mac Power PC as opposed to Intel based. Has been documented numerous times on the Leica Forum and Adobe Forums. Evidently upgrading to LR 2.6 (have to do it at Adobe's website) or going back to 2.4 takes care of things.

john bartlett Posted November 25, 2009 Author Share #3 Posted November 25, 2009 Reprocessed in Lightroom 2.3 No artefacts Many thanks for your help. Magenta cast in highlight possibly efffect of the red building opposite. I have not seen it in any of the other images. I will go and have a look at the site.

Guest WPalank Posted November 25, 2009 Share #4 Posted November 25, 2009 Glad to hear it John. LR 2.6 is a release candidate and is free at the Adobe site. Lightroom 2.6 - Adobe Labs Link to post Share on other sites More sharing options...
john bartlett Posted January 6, 2010 Author Share #5 Posted January 6, 2010 Further observations The recent update of light room has resolved the problem The possible magenta cast was indeed caused by the reflection of the building - so all is well Link to post Share on other sites More sharing options...
