I was curious to know if there would be a difference if the photo was sharpened before or after a crop. The photo I used was sharp to begin with so Topaz did not have much work to do. The results of my little test was that the final photos were identical when the original was brought up to the size of the cropped version.
No other editing was done - just the crop.
If anyone has done a similar test with photos that Topaz had to do some real work on, perhaps you would give us your results.

Recently a fellow posted the following photo asking about how it could be improved. Lots of comments were given to him. The sign was considered to be a distraction so I used Topaz ReMask 5.01 to remove the sign and Photoshop to clone in the background in this area. Next I used Topaz Sharpen A.I. to first improve the focus and then another run at sharpening. As I expect you can see, Sharpen A.I. make a nice improvement (see third image with original on left and enhanced on right). I note that ReMask is a wonderful tool either as a standalone or PS/LR plugin.

Thank you for your reply. I should have been clearer ... I was only looking for results for SharpenAI before and after cropping. Nice job by the way. I have been a Topaz Remask fan for many years.

Ah ha! Sorry about that. I have done the experiment you are looking for, but didn't keep the images. What I found was that it didn't matter as long as there was adequate content variation in the cropped image. Of course, as you know, it is best to process in RAW as long as possible.
FWIW, I have been amazed by the Topaz JPEG to RAW A.I. program. My testing has shown that the results are not quite the same as the original RAW files, but a lots better. Post-processing these "RAW" files works much better than the jpeg.

If you enlarge past 100% it is quite easy to see what Sharpen AI does. At lesser magnifications it is not obvious. It is only going to make a noticeable difference on large prints close up. But what it does there is quite amazing.
First is the whole frame
Second a small section unsharpened
Third the same section using Sharpen A!
This is Sharpen A! at 100%, which is higher than recommended and adds some artifacting--but just to see what it does clearly...

There should be little if any difference between the full size photo after sharpening and then cropping and cropping and then sharpening. The difference you would typically see is in the amount of time to sharpen the full versus the cropped. Fewer pixels to analyze in the cropped first. That has been my experience.

That's an eye opener, Thanks.
