I have a new teleprompter (DYI) but now I need to get the powerpoint slides mirrored. Obviously I can do this with Photoshop but I'm wondering if anyone has come across an easier way. I have hundreds of slides on a computer and I need to see them on the teleprompter as a mirror image. Any ideas?
Powerpoint>export as images> jpeg or TIF>into a new folder.
Photoshop> create batch action> Open>Edit>flip horizontal+save with same name in same folder> save batch action, automate> apply batch to specific powerpoint output folder, takes about a minute or less.
Create new blank powerpoint, import the images from the folder by dragging each image onto a blank slide. Save new presentation. Pray there are no late changes.
Or... buy a scan converter that can do a horizontal flip.
Note that it's built for PowerPoint 2003 and doesn't support PowerPoint 2007.
