SO I fired up Aperture today after a couple of months away from using it. I haven't updated my OS X version (10.6.8...I know, I know), Aperture version (3.2.4) or the underlying Digital Camera Raw version (3.24.0) recently. Nor have I updated firmware nor camera (5D-III, firmware 1.02 or something like that). No hardware changes to the computer either...in other words, everything (far as I know) is exactly the same as the last time I successfully used it.
Aperture will import images I just took this past weekend, but refuses to CLEARLY show them in the Main or Secondary window, only in the preview (Browser) bar in split view. By clearly I mean in focus, sharp and clear (and yes, they are properly focused based on what I see in Preview). It also states the image was adjusted using an earlier version of Apples RAW processing. Not possible since they were just taken Saturday and downloaded to the computer yesterday. My basic workflow is no different, either (download, first cull of the throwaways, more careful selection of those I back up (copy into a new folder reserved for pending backups) then move to their 'permanent' home file before opening Aperture and importing). If I click the 'reprocess' button, then I get a blank preview with the "unsupported image format' warning.
The other weird thing is even the majority of images that exist in current project files, that I have made numerous adjustments to in the past, don't respond to any changes made through the Adjustments panel today. I tried moving a variety of sliders, converting to B/W etc and the image displayed doesn't change. Nor, for most, does the histogram show. Although as my cursor moves through the image the R-G-B values change correspondingly, so some part of Aperture is 'seeing' the image. Now and then I found a random image that will display a histogram, and a few others that do respond to the adjustment sliders, but we're talking less than 10% of them, in various project files.
So before I spend a lot of time following dead ends, any ideas as to where I should start? I have my original Aperture CD so I could reinstall and re-update to 3.2.4 again if that seems to be consensus on where to start. But I'm stumped as to where to begin. Any advice is appreciated. If screen shots of what I see or don't see would help let me know.
