Aperture at ISO 80

I went up the Mendocino Coast this last week, shooting a lot of Nature. When I got back I tried to import them, and found that five images could not be recognized by Aperture. It did import them, but Aperture found them to be unreadable. I tried LR and C1, and both worked correctly. So I looked to see what was the difference between these images and the other 320 or so images, I shot. The only difference I could see what that these had been shot at ISO Pull 80. Have others found this to be true? Is there a workaround?

Must be an Aperture bug, since my ISO Pull 80 shots are read fine by Adobe Camera Raw (and, I presume, its cousin Lightroom).

 

Actually I think it's a Mac OSX bug, since I get the same problem in iPhoto, and when browsing as a Cover Flow. I can see all the other DNG files, just not these files with the ISO Pull 80. Yes, they work fine in LR.

I'm using a Mac and the Pull 80 dngs are displayed no differently from other ISO shots in the Finder, for example, or the preview pane in the "Get Info" boxes about the files.

 

So it sounds more like specific Apple applications rather than the OS itself (snow Leopard 10.6.2 in my case)

Interesting, I am using Snow Leopard 10.6.2 and the finder does not display the ISO 80 shots. The info Panel does shows the dimensions as 0X0 file size as 17.9mb. At this point I can repeat it at will.

Weird. Just to check, I though it might be a compressed vs uncompressed DNG thing - but tested that and my Mac can "see" both types.

 

The other thing to check might be - have the invisible files never been opened and been adjusted in LR or C1? Because all of mine have had adjustments made in Camera Raw, so I can't tell if a "virgin" M9 .dng would turn up invisible.

 

last one - are you running Rosetta (backwards compatability for PowerPC software on Intel Macs)? I know of no reason why this would make a difference, but I do have it loaded to handle old scanning software.

Hmm I have used only Uncompressed DNG files. I have C1 and LR installed but have never used them until this issue came up. The images were imported directly from the SD card into Aperture. I left the chip mounted, and browsed directly in the OS.

 

I think I installed Rosetta, but do not see it in the system profiler. I am using an Intel based Mac.

Interesting ! I had the same problem with my mac ! In my old Canon EOS 40D just before Chrismas I converted SRAW to DNG. While I in finder could see preview of the SRAW file I could not se it in DNG. It also show size 0*0. I had no problem with original RAW "CR2" and this conversion to DNG. I have tried conversion with LR as well as RAW converter.

 

If I look in EXIF data in LR the correct size is set. So question is: Does anyone know how MAC finder read EXIF - and is there a tool (MAC) where you could correct your EXIF / compare EXIF from the "2 different" DNG's.

 

Seeing this threat - I tried ISO 80 shots from my Leica - and I had no problems.
