LR brighter than PS

LR 2.4, PS CS4, Mac OS 10.5.7. Images start as Canon 5d2 raws and edited to layered Adobe RGB 16-bit tiff.

I export ''original w/ LR settings'' to PS, edit, save, and notice when the preview in LR updates it is (maybe ~10-15%) brighter than the file in PS.

I assumed LR was previewing the file incorrectly, however, jpegs made of these files via LR are also brighter than those made via Bridge and ditto for PDFs.

Tangential or unrelated question here too.

Some of my layered Tiffs end up larger than 2GB and upon saving PS warns me that files over 2GB might not preview correctly in other apps. However, in Bridge files over 1GB are previewing as postage stamp thumbnails.

Thanks

Check your PS Preferences, [Edit-%26gt; Color settings-%26gt; Advanced] and make sure the brightness adjustment box is off.

John, I don't see a brightness checkbox. I'm using ''North American Prepress 2'' defaults. Thanks.

There's a possibility that your display calibration profile is corrupt. Try recalibrating the display.

Ian, I'm not sure how to interpret and test your solution. Are you saying that a corrupt monitor profile will make two identical files look different when viewed side by side, or that the corrupt profile will cause the applications to produce non-identical files?

It's at the bottom, and is called Desaturate Monitor.....?boxes should be unchecked.

If two files are in fact identical and viewed in the same application, they will view identically, unless you have a very strange monitor! Two identical files should view the same in LR and PS, unless the Sat. setting is changed per previous post. If photos have a different color space, they should look the same in color managed apps, unless the monitor's profile is off.
