Getting this grid view for you, the reader, was an exercise in batch processing in and of itself. Perhaps there is a built-in preset for this already, but I do not know of one and had to do some digging around:
1. I did the storyboarding in a free IOS app called PAPER. After one week, I don't know how people ever storyboarded without the ease and cross-functionality of Paper. It exports entire works as a .pdf to e-mail, it exports individual "frames" to facebook, twitter, your photo album - it even does your laundry. It might even be able to refinance your home.
2. Of the options from the above laundry list, I exported the entire 42 frames to a .pdf and e-mailed it to myself.
3. I saved the .pdf to my Google Drive.
4. I opened the .pdf straight up in Photoshop CS6 - should be no different for recent versions, particularly the cloud-based one.
5. Select all images.
6. Open up the ACTIONS box. You're going to record the process of exporting to a .jpg.
7. Click the PAGE icon to create a new recording, name it, and then start recording.
8. Save your image as a .jpg. For this exercise, I picked medium quality. I then closed the tab with the image inside Photoshop and hit the stop button on the record. So this action will export an image to my folder (of choice) as a .jpg, then close the blasted image inside of Photoshop so I don't have to deal with it anymore in the batch process (or annoying pop-ups about saving). Now you're ready to tackle the other photos.
9. Batch process - under File, look for Automate, then click on Batch.
10. Make sure the BATCH dialog box shows your newly minted action. Check the SOURCE to make sure it's going to pull from your opened files.
11. Tell the DESTINATION to be a folder. Then CHOOSE which folder - I started with this .pdf in my Google Drive, so I left the contents there in a companion folder called "demo."
12. Finito. After executing the batch, check your destination folder. You're done. Apart from the naming scheme, the end products are there and ready to be used. E.g. I uploaded all of them into the grid at the top of this post.
