I finished editing my first photo and now I want to use is in PowerPoint. PowerPoint says "an error occured while inserting this file." The file is a .psd. Thank you!
The Photoshop PSD file is used by Photoshop, and won't be understood by PowerPoint. Think of the PSD file as you work area, the place you create and edit and build your creation. Then, when you are done, you save it in a format that other programs can use. Like this:
One last note. If you then go back to Photoshop to make changes to your original PSD file, you'll need to go through the Save As steps again.
