In my experience, version control is one issue that has always existed in the design world. Since devs are used to obscure commands and “mentally-challenged” user interfaces, typing
git add . & git commit -a isn’t a big deal. Designers are different.
Save as... is the typical version control method for many, and any attempt to force designers to use p4v might lead to mass suicide.
LayerVault tries to solve this problem by plugging directly into Photoshop. A simple
Command + S automatically saves a revision. Then, you can view the file’s history in a timeline interface that shows a clear diff of the changes.
Unfortunately, LayerVault is currently in a closed beta, so I don’t have any invites to hand out, or even one for myself! For now, you can watch the video below, apply for access, and cross your fingers.
