Straightening Scans In 10 Seconds (Or Less)
If you’ve scanned an image and it’s crooked when you bring it into Photoshop, you can fix it in about 10 seconds flat. Just switch to the Measure tool (it lives behind the Eyedropper tool in the Toolbox) and drag it along the top edge of the image you want to straighten. That’s the hard part (and that should give you an idea of how easy this technique is). Next, go under the Image menu, under Rotate Canvas, and choose Arbitrary. Photoshop automatically enters the amount of rotation (courtesy of your earlier measurement), so all you have to do is click OK and bam!—the image is perfectly straightened.

Document Your Happy Accidents
Sometimes our best creations happen by pure experimentation and accident. Sitting in front of a Photoshop file, you are 40 History States in, and then it happens—magic! You really want to be able to get back to that moment. To do so, make sure that you turn on the History Log checkbox in the General Preferences (Photoshop>Preferences>General [PC: Edit>Preferences>General]). You can save the information as metadata, as a separate text file, or both!

Great job on the blog/site Corey and also the consistently incredible work you do on Layers TV. I use this feature almost daily in my work and have streamlined it a bit with some shortcuts. First I access the measure tool by pressing ‘ i ‘ 3 times (to toggle through the tools in that bin). Then I use my custom shortcut for the ‘rotate arbitrary’ command which is [ctrl] [shift] [alt] [A], and I’m done.
