Please follow the below instructions.
- In the Finder, navigate to your iPhoto package file. By default, it's located in /Users/[user name]/Pictures, and it's called iPhoto Library.
- Control-click the iPhoto Library file and choose Show Package Contents.
A Finder window opens that shows the contents of the package file. The Masters folder contains all of the photos that are in iPhoto. However, Photoshop cannot access this folder.
- Control-click the folder named Masters and choose Duplicate.
- Drag the folder named "Masters copy" from the iPhoto Library Finder window to your Desktop. Now you can open images from the desktop in Photoshop.Thank you for posting on Adobe Forums.
That's great, because I realized instantly that the problem was the Mac deciding everything should go into iPhoto. I always try to have my photos go to a drive as stand alone files so that I can open them in whatever program I need. Thanks.
Glad to help you out.
