For its latest major release, popular camera app VSCO Cam has added batch photo editing, an undo edit button and performance improvements. The new batch editing feature, aka Copy + Paste, lets you make a complex set of edits to just one photo, then copy that set of edits and apply it to other photos you've taken already. It's kind of like an edit preset, but made to be used on a shorter-term basis, and it should really cut down on editing large sets of photos.
Rounding out the features of this version 3.2 release are a new undo button in edit mode and "dramatically decreased" editing times, which are both nice little updates. You can grab the latest version of VSCO Cam from the App Store at the link below.
