Q: reduction in file size after migration from iPhoto to Photos

After migrating an existing iPhoto library to the Photo app (mac OS), the files in the new Photo library are greatly reduced in size. How do I locate my original, full size images?

    That does not happen - in fact photos uses the exact same image files that iPhoto uses - Photos saves disk space by sharing images with your iPhoto or Aperture libraries - Apple Support - same files with hard links to them

     

    Please explain why you think your files are smaller now

    Hi Larry,

     

    You obviously have far more experience with Macs and iPhoto/Photos than I do.  Although Photos may use the same image as iPhotos I appear to have lost a lot of functionality after the upgrade:  editing, location, faces identification etc.

     

    Are those functions still available and if so how do I access them?

     

    Grateful for any help.

    @DAAW

     

    Your question has nothing to do with this thread in any way - ThreadJacking is Rude and having multiple questions in the same thread is very confusing to you, to other readers, to the Original Poster and to the volunteers trying to help - please start a new thread for new questions - click not the word "new" to the right of the "Apple Support Communities" banner at the top of the page and include specifics of your system and of the problem

    The image sizes are listed as 150K. They were taken with a dSLR that doesn't have a resolution this low.

     

    My iPhoto app will not open after the OS upgrade so I can't go back and check the size in iPhoto. Regardless, the images are this size when opened on a PC.

    where are you seeing this "image Size"  --  to see an image size in Photos right click on a photo and get info - the image dimensions and size are shown - it will be the same as in iPhoto

     

    as to iPhoto you have to have version 9.6.1 for OS X 10.10.3 - see Why won't my iPhotos open?
