Now that Xsi support is out - how to update Aperture library?

I have what I believe to be the same problem. Newly imported .CR2 files from Rebel XSi seem to function appropriately. However, previously imported files are still shown as 256 x 170 pixel by EXIF and previews even though they take 14MB in space. Generating new previews doesn't fix it. New versions from the JPEG masters are the right size (I shoot JPEG+RAW). Updating EXIF from Master now gets new information it couldn't from before.

Overall, it seems like support for this RAW format is either incomplete or just harder to implement retroactively.

Try "migrating" the images to the RAW 2.0 decoder. (Yes, they probably already are on it, but maybe attempting it again will make the system re-process the files.)

Read http://docs.info.apple.com/article.html?artnum=307399 for the migration procedure.

Had already tried that, but as you predicted, they are already using the 2.0 decoder. In fact, legacy decoders don't even appear to be an option...

does a rebuild of the library work ??? command+option at aperture startup ...

a "last" resort might be to export those 450D masters to a new folder and reimport that folder as a new project ...

No, a rebuild here won't help, you will need to import the xsi's again, now that they are actually supported by the app/os.

So unfortunately, I deleted the original files off of my SD card after importing to Aperture. I tested exporting & re-importing on a small batch of files and it seems to work okay as far as properly handling the RAW.

My question now is: Is there a simple way to have Aperture treat the JPEG/RAW image pairs intelligently again? Originally, it recognized that I was shooting in JPEG+RAW and treated the pair of files as one item in the libarary. I don't want to create a stack, as that's much messier and not equivalent.

Thanks for everyone's patience and assistance so far.

i seem to recall a post by apple saying that they will just "work" when the camera is supported ... they never mentioned that you'd have to reimport ...

i know that when my 1ds files were unsupported - nothing - and then when support was available, they just all of the sudden worked ...

figured a rebuild could help ... and it definitely won't hurt ... and unless you tried a rebuild and it didn't help you, not sure why you are telling them to not try it ... :P

Unless Clem knows for sure, which is certainly possible. Maybe he has tried it 😉

ah ... he must know for sure ... 😉

Ok, so I'll say, I don't believe the rebuild will help, but its true it wouldn't hurt ( just something you will spend time on, when you could otherwise be reimporting which is sure to work ) 🙂

as noted by Jen Chang, the reimport screws up her RAW+JPG ... whereas, if it works, a rebuild would not break their link ...

therefore i firmly stand by my suggestion to at least try it ...

😀

What happens if you export projects and reimport those?

I just did a Metadata->Update EXIF from Master on one of the images that was stuck as a thumbnail, and it worked.

That might be the fix - select all images of thumbnail size and update the exif data, and it might all just work. Will try now.

(Matter of fact, you really do have to do that - because you don't pull in all of the metadata from the raw files if you don't.)
