Originally posted by bawill I am having some trouble with Pentax RAW files in iPhoto on my mac. As far as I can tell, this is a problem whether I shoot in PEF or DNG. Many of my photos end up being solid black in iPhoto. I used to have a trial version of Aperture 2, and some of the photos showed up as solid blue in that program (the same photos showed up as black in iPhoto). This is a problem that seems to be getting more frequent. The pictures show up fine when I preview them in the finder. But once they are in iPhoto, a number of them show come up as solid black. Any ideas about what may be wrong? It seems strange that the frequency of this problem seems to be increasing. It also seems weird that the pictures preview okay in the Finder but give me trouble in iPhoto. I also just opened one in the Pentax Photo Laboratory program and was able to make adjustments okay. This issue is driving me crazy. Any ideas? I would be suspect of my SDHC cards, except that I am able to see the pictures okay in Finder and in Pentax Photo Laboratory.
Create a new (test) account and see what happens when you import the files to iPhoto.

PhotoLab works fine for me. Finder sees the file but can't read/thumbnail it. Preview doesn't work. IPhoto (which I hate) won't read the file. So you are waaaaay ahead of me.

There was a software update a few months ago that enabled one to view Pentax PEF files with Preview among other things. It's only for Macs with iLife 08 installed, and OS X 10.5 I think.
Originally posted by bawill So if I delete the iPhoto preference files from the library folder and then reopen iPhoto, that might help?
It might not be iPhoto's preference file that is corrupt, but then again it could be too. What I mean is a different corrupt preference file may be affecting iPhoto. I once had the dates in iPhoto and Apple Mail all showing the same date for all the photos and e-mails spanning a few years. I deleted iPhoto's and Mail's preference file but the same date showed. To make a long story short I found a preference file in duplicate (I don't know which was one corrupted but since a new one was created I deleted both of them) that was causing iPhoto and Mail to show the same dates for all photos and e-mails. I deleted those preference files and now iPhoto and Mail show the right dates.
After deleting preference files you should logout of your account and back in to create new preference files.
Quote: One thing I realized this afternoon is that the issue became a serious issue when I switched from the sRGB setting to the AdobeRGB setting on my camera. I think I had an issue with several photos before this, but the issue got totally out of hand after I switched over. What would cause that? Does iPhoto not like AdobeRGB?
I don't know if this will help but try using Image Capture to import the PEF files to the HD and import them to iPhoto. There is an option to embed a color sync profile to the images, one of the choices is to use the cameras profile.
