I've always heard that Adobe Photoshop will not allow you to import pictures of U.S. currency because you could potentially be using the software to "copy money." Today I ran across a video that also claims that all current copy machines will not copy currency due to a hidden pattern on the bills. I decided to put this to the test.
First I decided to test Photoshop. I went to Google and searched for "20 dollar bill." I copied two different images of $20 bills and imported them into Photoshop without any issue. I wasn't sure that these images were doctored so I decided to take my own picture. I pulled a $20 bill out of my wallet and took a picture of it. I was able to import this image into Photoshop as well without any issue.
I then tried to take a screenshot of Photoshop open with money being edited. When I tried to copy that screenshot into a new Photoshop Document, I finally got the error.
For some reason Photoshop did allow me to edit three different $20 bills but wouldn't allow me to import them again as a screenshot. To get that first shot of the bills in Photoshop I had to import my screenshot into Microsoft Paint, crop it, and save it.
We have a black and white printer/copier/scanner in our office and I decided to test that next. I took my $20 and was able to make copies of both sides of the bill without any issue.
So what's going on here? Why is Photoshop only blocking me part of the time? Why does my copier, which is new, still allow me to make copies? Is it because it's black and white? If you know the answer I'd love to hear it.
