Hi, I am a long-time Aperture user and have a Canon 50D. I updated Aperture to version 3.1.2 (from 3.1.1) on 4/16. Starting on that date, all of my new raw photos began showing a hot pixel (green bright dot) towards the bottom centre of the photo. Lightroom does not have this problem and I blame the update because I do not see this artifact on photos that are older than 4.16.
Is there anything I can do (including version rollback, which I don't know how to do)?
Art,
Very curious. Let’s test the theory first—choose a photo that is pre 4/16, that you don’t particularly care about, and choose to reprocess the master from the menu Photos > Reprocess Masters…. If it refuses to because it’s already up-to-date, then I think we’re looking at a different issue. If it does and the green dot shows up, then we know we’re on the right track.
The green dot is usually a stuck pixel on the sensor, but I believe that the RAW decode is designed to look for and eliminate those. I’m not 100% sure about that, but I think that’s the case.
Anyway, one step at a time.

Thanks for your reply. After digging through the library a bit more, I found examples of such a dot on files that are older than 4/16 (they were just not as prominent). I’m sending the unit in for cleaning and hopefully that will address the issue.
Art,
Good stuff. In the meantime, it should be easy to fix on existing photos. Be sure to zoom in to 100% and using the Retouch tool (“x” is the keyboard shortcut) [screenshot] make the circle just barely bigger than the spot, opacity at 1 (full) and you should be able to heal it in one click [screenshot].
Then, lift and stamp that across all the images that have the green dot, and you should be good to go! Unless that dot happens to land just on a line, odds are this simple fix will fix ‘em all up very very well.

This is in fact an artifact of Aperture 3.1.2: I have the same problem. Older photos which I imported into Aperture summer 2010 did show very faint hot pixels but when I hit the “reprocess” button, they show up very strong (like they do on all photos which I imported into Aperture 3.1.2). So there is definitely something wrong with Aperture 3.1.2.
Andreas,
This is an older post relating to Aperture 3.1.2, but the current version is 3.2.1. Can you confirm where you are seeing this?
