VSCO Film for ACR 9, 8 & 7: I selected a preset a while back and now I want to just turn that off. Can I do this?

ACR doesn't have layers like photoshop does, so VSCO Film and the VSCO Film Toolkit aren't adding things that you can later remove so much as they are adjusting things that are already there. Most items have a - version or an off version that you can apply at any time, but the only way to backtrack specific adjustments is to use the undo function.

In ACR, the undo shortcut is your only option. To undo more than just the last adjustment, hit command + option + z (mac) or Control + Option + Z (PC).
