    What lossless means is that no changes are committed to the photo until you export or print the image. Further, even then, you can continue to edit the photo without losing data as you can revert to the original or step back along the edit history, fork then version to othe versions endlessly, again without losing any of the data in the image.

     

    Photoshop format is not lossless, it is not compressed. it's perfectly possible to edit a photo in psd and lose data. That's because Photoshop is a file editor. iPhoto isn't.

     

    Virtual means that when you duplicate a photo in iPhoto no extra file is created. You see two versions of the photo based on the same file. Saves disk space.

     

    The fact that something is "real enough for me" is interesting autobigraphy, thanks for sharing.

     

    You say you don't access your photos the same way? Why not? There are a variety of ways to access photos in iPhoto - essentially via Media Browsers, Drag and Drop or Exporting. That was the same in iPhoto 09. What has changed for you?

     

     

    Well, except that Aperture is actually like Lightroom, not iPhoto, and offers a workflow experience that is more akin to Photoshop than iPhoto.

     

     

    Huh? Have you ever used any of these apps? iPhoto, Aperture and Lighroom are exactly the same kind of app. They are Digital Asset Mangers that offer database driven lossless processing. They take exactly the same place in the workflow. That's why using more than one of them makes no sense. All of them can use Photoshop as an editor. There is no usage scenario for Aperture, Lightroom or iPhoto that is "more akin to Photoshop". That's like saying Word is the same as Excel.

     

    Sure sounds to me like you have either a corrupted Library or have not set your external editor correctly. There is no supported scenario where you access a file within the Library package.

    Sorry but again you are incorrect.

     

    The first part of this sentence

    If it's a lossless format (like AIFF or PSD) no information is lost due to file compression

     

     

    Does not mean the same as the second part:

     

    - you can edit the file as many times as you like and still there is no loss of information.

     

    Really? Here's a simple test. Open a psd in Photoshop. Crop to 50% of the size. Save it as a psd. Is the psd the same size? Or have you just cut about 50% of the data out of it.

     

    Do the same in iPhoto. Open a psd, crop 50% out of it. Now look at the the psd again, anything changed? No.

     

    Lossless means lossless regardless of the file you use. iPhoto is not "quasi-lossless". As it never changes the original file it is as lossless as this gets. Just as lossless as Aperture and Lightroom. You can step back your changes, have endless versions and so on.

    As a last ditch thing, you might try deleting the iPhoto preference file.

    I am not sure what you mean by this, but if it involves changing things in the iPhoto Library file, then it will create more problems. After you send the file to the external editor, iPhoto should just be looking in the oddly named temporary directory for the file to be changed so it can re-import it. Somehow, that process has been broken.

     

    As a long shot, you might also want to use the repair library function and repair permissions.

     

    PS, you are correct "non-destructive" is a better term than "lossless".

    I will open my mouth, remove my foot for just long enough to say, you're right, all along I meant 'non-destructive'...

     

    Sorry for being pig headed.

    first rule of iPhoto  --  NEVER use the finder to make any changes of any sort to the structure or content of the iPhoto library - it does not work and is likely to corrupt your library causing loss of data and maybe photos

    Second rule of iPhoto - what happens in iPhoto stays in iPhoto.

    Did you delete the preference file?

    Another thing to try is to create a new iPhoto Library and fill it with a few images, does it happen there?

     

    If it still does, create a new user, start iPhoto and see if it *still* happens.
