How do I transfer photos in iPhoto to Photoshop?

Question

Currently running iMac with Mavericks operating system. Need to transfer all my photos from iPhoto (version 9.5) to Photoshop CS5. Would appreciate any help!

Answer 1

It depends what you mean by "transfer." iPhoto manages photos in its own package while Photoshop doesn't store or manage any files, so "transferring" images from iPhoto to Photoshop doesn't make sense.
Do you mean you want to open iPhoto images in Photoshop? That part is easy, and there's more than one way to do it.
When you're looking at a photo thumbnail in iPhoto, drag it to the Photoshop icon in the dock. The image will open in Photoshop.
In iPhoto Preferences, click Advanced and use the Edit Photos option to choose Photoshop as an external editor. After you do that, pressing Return for a selected photo in iPhoto will pop it open in Photoshop for editing.
With either method, after you edit and save a new version in Photoshop, if you want to manage it in iPhoto you'll probably have to manually drag the new version to iPhoto. (Just don't save new files into the hidden folders iPhoto manages.)
While it's true that iPhoto keeps photos in a hidden package, the methods above let you easily use the photos in other Mac programs. iPhoto also has a File > Reveal in Finder command so you can always reveal the actual location of a file managed by iPhoto. This is useful if you want to copy a photo to a folder outside of the iPhoto Library so you can manage it with Bridge instead.
