Good tip Doug. I never thought about it, but it sounds like common sense.

Debbie,

Although I don't know for sure, I tend to think that even if you do crop, it will work as long as you don't change the size because the underlying information should be the same. Could be wrong though. Comments Doug?

Sounds like a good excuse for an experiment.

Let us know how it comes out

Experiment done. Wrong as usual. Now I have to wonder why it won't work with a cropped image. I can understand it when you change image size (I think) (but I'm probably wrong again). . But the important thing is I learned something.

I assumed it would be the same with crop because you do change the image pixel size. I believe from what Doug has pointed out that the history brush views a photo as x amount of pixels by x amount of pixels and when you crop you cut off some of those pixels. So it's basically the same as resizing. Instead of having an image that is 1000 x 1000 pixels say, you use the crop and your image is maybe 980 x 700 pixels. That leaves the history brush without the same reference grid. I believe that is what is happening. When Doug said it, it suddenly made sense to me. Kind of like a light bulb coming on.

Doug
That might be a good tip to list on it's own in the tips area so others can see it. I bet I'm not the only one who wondered why my history brush didn't work no matter what I did, not even thinking about having used the crop tool. It could save alot of mind bending time to figure out the problem. Like me, I imagine alot of people do a crop as one of the beginning processes even to straighten out a slightly crooked scan. That would also mean that the rotate arbitrary would affect the history brush also as Tim pointed out in a tip to straighten a scan. As would any changes to canvas size. It might be a good idea to point out that anytime you resize or crop you might want to create another snapshot for future history brush use.

so if you crop right out of the gate or otherwise change the image size, you should/could paste it into a new document which would be none the wiser, right?
