If you have photos with distracting elements on the edges, or feel that your photo would have had more impact if you had moved in closer, the Crop Tool will allow you to fix these problems after the fact.
Using the Crop Tool is as simple as finding in among the tool choices, selecting it, and then clicking and dragging the mouse along your photo to create a Crop Box. This box represents what you will keep when you hit the Enter key. Once you get the hang of it, you’ll wonder how you lived without trimming your images with this simple tool!
Leveling Horizons: Furthermore, if you have an image with the horizon not perfectly level, you can easily make it level again with the Crop Tool.
In Photoshop or Photoshop Elements, you can correct slightly askew horizons by clicking on the Curved Arrow Cursor just outside of each corner of your Crop Box. I use this method all the time as a quick and easy way to fix unlevel horizons. This is one of the tricks covered in the Photoshop for Photographers online course right here at BetterPhoto.com.
