I shoot RAW + Jpeg with my cameras... Up until a recent upgrade to Mavericks... I would put the SD card in the iMac and it would import all the JPEGs, and then say something like 75 files could not be downloaded.
Those were the large RAW files and I would then just move them to an External Hard-drive and use Lightroom and Canon's DPP to edit them.
After the OS upgrade the RAW and JPEGs now both import into iPhoto and onto the Mac Hard-drive.
I can't seem to find a way to not import the RAW file into iPhoto. Is there something I am missing? I do not want those large RAW files wasting space on the mac, and I have notice iPhoto is really slow since the upgrade.
Thanks for any help
A. To move an iPhoto Library:
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
B. iPhoto and Raw
1. The Raw processing engine in iPhoto the same one used in Aperture, but with less fine control. (Think of the differences between Word and TextEdit, iMovie and Final Cut).
2. Processing Raw in a 3rd Party Application
You can also process your Raw with a 3rd Party app like ACR or Photoshop. But iPhoto does not handle this gracefully and it's a bit of a kludge.
First off set your preferred app as an external editor in iPhoto:
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.
Note that iPhoto sends a copy+ of the file to Photoshop, so when you save be sure to use the Save command, not Save As... If you use Save As then you're creating a new file and iPhoto has no way of knowing about this new file. iPhoto is preserving your original anyway.
Next: In the iPhoto Preferences -> Advanced, elect to use Raw with your External editor:
Now when you go to edit the Raw it will be sent to your external editor.
Now for the kludge:
You cannot save a Raw. The work you do must be output to a new file, in a new format (jepg, tiff, whatever). However, as the External Editor is making this new file iPhoto has no knowledge of its existence. Therefore you must save it to the desktop and then import it back to iPhoto as a new file.
This means that you will have your Original Raw and the processed version in iPhoto but they will not be recognised as version and original. iPhoto will see them as two separate shots.
Further - and this is quite a consideration: Lightroom is not an editor. Like iPhoto it's a database app and images need to be imported, processed and exported from it. It occupies the same place in the workflow (manager/non-destructive processing) as iPhoto does so in makes zero sense to use both...
