Straighten your horizons in just a few clicks

It's pretty common to to be given a tilted photo to use on a project. I find the tilted horizon to be distracting so a straightening is in order. Most of the time I see people placing a line or rule over the photo and straightening a photo by sight. This may be adequate for some photos, however, if accuracy and speed are are necessary this trick will allow you to straighten photos like a pro.

This is old trick to fix photos with slanted horizons. I think Scott Kelby demonstrated this technique way back in photoshop 5 so it's not a new trick by any stretch of the imagination. Designers today are still amazed when I show it to them. This trick is so simple and so easily overlooked that I just had to put it out there one more time for anyone that might be newer to photoshop or work infrequently in the program.

1. Select the measuring tool. It's hidden under the eyedropper tool. Or you can press the letter "i" a few times until it comes up.
2. Start at one side of your picture and drag the ruler over your horizon to the opposite side.

3. Select Image > Rotate Canvas > Arbitrary. A pop up will appear over your image the the proper rotation amount already filled in. There is no need to do anything here accept press enter to accept the value.
