Photo/Scan software that will orient crooked scans?
 

I have a ton of cards that I want to scan and archive, but it drives me crazy when the cards aren't exactly square when I crop them. So I spent a ton of time trying to orient them exactly straight on the scanner, which is frustrating and time consuming. I'd like to be able to just thrown them on the scanner and then straighten/crop them on the computer, but at the moment I'm just using Paint, which only lets you rotate 90/180 degrees.

Can anyone recommend some basic photo/scan editing software that has a micro-orientation tool that will let you square things up perfectly before you crop them?

Thanks!

If you have Windows 10, the Photo program has an editing feature. Click on one of the JPG files and it should open up the Photo program. The Edit Button is one of the icons on the top right (a rectangle with a pencil across it). If you click it, there's a large icon on the top that says "Crop and Rotate". When that opens up you'll see a vertically shaped arc made up with a set of small dots with a large dot in the middle. Run your mouse over that large dot up or down and it will rotate your photo in 1 degree increments.

Good luck!

That's good to know. One of the programs on the old computer had a "straighten" function that did pretty much the same, but without indicating the degrees. It also changed the zoom as the straightening happened, so it wasn't all that great. I don't recall what the program was, maybe an earlier version of the current one in Windows?
I had something like five or six photo programs and didn't really like any of them. Individual features were nice but none of them really put it all together.

Thanks for the replies. I tried the Windows 10 photo program, but it didn't work that well for me. I actually found a free program yesterday called Rotation Pilot that will let you rotate to 1/10th of a degree. You can also draw the correct "horizon" using your mouse to drag a line across the bottom edge of the card/slab, and it will automatically rotate the scan to that horizon.

It's a little cumbersome because I have to do the scan, then open it in Rotation Pilot to fix the orientation, and then open in Paint to crop/edit. But, it gets everything completely square and it's a whole lot easier and faster that getting a perfect 90-degree angle on the scanner.
