Hello,

 

Randomly I get the odd preview thumbnail looking dark green (whilst the rest of the album is fine).  When I load the image it looks as it should but when I go back to thumbnails it looks odd again.

 

This wasn't too much of a problem until I noticed it started affecting the image on Facebook (uploaded fine on Facebook last week but when I checked the album on facebook today some of the photographs now have the same dark green hue as the previews on Aperture).

 

I shoot in RAW on a Canon 50D. I import to finder first then from there into Aperture.

 

Any assistance appreciated.

    Did you try rebuilding the aperture library?  Importing the pictures directly into aperture, you have options to keep original previews or have it created by Aperture. I'm new at Aperture, and got most of it iron out, so far.  Using it for the D800, only raw (average 45mb files). Reasonalby fast, but processing can take some time.

    Hello TheScotty-

    Alyoops' suggestion is sound and may very well solve your problem, but rebuilding the library can be pretty time-intensive and is better saved if other, quicker approaches don't work. Firstly, make sure you're working with the latest version of the RAW decoder: Open System Preferences, then click on Software Update and finally click Show Updates. Depending on the version of Aperture you have (original version installed from a DVD, or downloaded from the Mac App Store), you'll get either a window listing any available updates or the Mac App Store will open to the Updates page. Install anything that resembles "Digital Camera Raw Compatibility Update", if available.

     

    After that, launch Aperture and select one or more of the thumbnails with the green cast. From the Photos menu, select Reprocess Original... and use the default settings ("All phototos" and "Reprocess existing images"). This will reprocess all of the selected thumbnails (*not* the entire library, just the selected ones, fear not). When that completes, select Generate Thumbnails from the Photos menu. You will see a small spinner graphic at the bottom left/middle of the Aperture window, just next to the Rotate/Lift/Stamp buttons, while Aperture regenerates the selected thumbnails. Usually this fixes issues like what you're experiencing; see if that helps.

     

    If you're still getting the green cast, give alyoops' suggestion a try and rebuild the library: To do this, quit Aperture, then hold down the Option key while you launch Aperture to bring up the Library First Aid window. Select Rebuild Library, then click Rebuild. Note that this can be a lengthy operation for large libraries.

     

    Good luck!
