What is considered the best way to convert a multipage PDF into single page JPG's with photoshop CS3?
I'm looking for a (semi) automated process since it's a 150 page pdf so a little cumbersome to do manually.
I know you asked about Photoshop but... If you have a Mac this is very easy to do using Automator. You just need three actions:
You can even select the color model, format (12 available), resolution and compression quality. Just to test it out, I converted a PDF file I have here with 207 pages:
Using "600dpi/RGB/best quality possible" it took an hour to convert to JPEG.
Using "300dpi/RGB/60% quality" it took about 5 minutes to convert to JPEG.
