Guest V64 Posted September 16, 2009 Share #1 Posted September 16, 2009 Advertisement (gone after registration) I have just updated to this new version - and immediately noticed that any 'over exposed' highlights were contaminated with bright red speckles and lines. Reducing exposure had no effect, and the effect was also shown in an export tif file Here is a 100% crop from a chrome strip on a car. [ATTACH]162538[/ATTACH] Anyone else see this?

Gismoto Posted September 16, 2009 Share #2 Posted September 16, 2009 Which camera files did you use? Link to post Share on other sites More sharing options...
Guest V64 Posted September 16, 2009 Share #3 Posted September 16, 2009 Which camera files did you use? The source file was an M8 RAW, exported in ProPhoto color at 16 bits TIF format. Here is approximately the same crop done in LR2.4 [ATTACH]162558[/ATTACH] I installed 2.5 over 2.4 and then 2.4 over 2.5 - in both cases I used the settings that came as the default.

Guest V64 Posted September 17, 2009 Share #4 Posted September 17, 2009 Further research on the various Adobe/Lightroom forii suggest this is a Mac G5 PPC/Tiger? issue. Lets hope that this will not turn out to be the first step towards Adobe dropping support for this system, and we get some kind of fix, otherwise M9 users may have a problem Link to post Share on other sites More sharing options...
UliWer Posted September 17, 2009 Share #5 Posted September 17, 2009 Are you sure,that's not the feature for showing overexposed patches in the photos? Just try to change the settings for this feature and look again. Link to post Share on other sites More sharing options...
Guest V64 Posted September 17, 2009 Share #6 Posted September 17, 2009 It is definitely not the Highlight Over/Under exposure feature - since it appears within the exported image as well as in the LR perview Link to post Share on other sites More sharing options...
