Cropping outside the image area in ACR

I would really like to be able to "crop" outside the image in ACR.

The limitation that ACR can only crop into the image, not beyond it, makes ACR's straighten tool basically useless because it throws away so much image area. Allow us to "crop" outside the image, creating blank spaces we can later fill in, just like in Photoshop.

Why don't I just do it in Photoshop? Because the old-fashioned workflow of having a bunch of layered PSD's of every step of my editing process of every single image I work on is impractical. And even if you keep everything on layers much of it still goes out the window if you find you need to go back to ACR to change sharpening settings or something. It's much better to keep as much as possible in a small, repeatable sidecar xml. I'm certainly not asking to be able to store the filling in those blank spaces in a sidecar file (or anything else particularly advanced) just to be able to store the crop itself.

In the Lens Corrections - Manual area, the Rotate (perhaps combined with Scale) operations, without the Constrain Crop enabled, will do as you say, allow non-image to show at the edges without resizing things smaller. Straightening via a Rotate slider/type-in isn't as easy as dragging a ruler but you might be able to get it to work.

Otherwise shoot wider than your finished product so you have extra room to straighten.

Thanks, but that's not really what I mean. That's just downscaling the image so that it can be rotated within the original image area. Throwing away data via downscaling isn't as bad as having to crop away parts of the image, but it still isn't great. What is needed is the ability to ADD [blank] image area so no data is lost.

You bring up an interesting point, though, mentioning that Constrain to Image option in the crop tool. I'd expect unchecking that to do exactly what I'm asking for, but I can't tell that it does anything.

Updated to make reply relevant to ACR instead of Lightroom.

The Constrain to Image in Crop just turns it on for the lens-corrections area. I guess it's for when you're adjusting the crop after doing lens corrections with the constrain off and don't want to have to go and turn it on there.

Scaling down to 50% Lens Corrections-Manual then doing Open Image with a 200% Resize set in Workflow Options does result in a blurrier-than-100% image rather than the two cancelling each other out, which is unfortunate.
