Cropping and/or straightening your photos can be initiated in one of three ways:

  • tapping the “r” key,
  • selecting “View” and then “Crop” from the menu, or
  • clicking the “Crop Overlay” button displayed in the command bar underneath your photos in the Develop module.

All three are equivalent. Once invoked, the command will overlay a grid of two evenly–spaced vertical and two evenly–spaced horizontal lines on your photo to make cropping your photo with the “rule of thirds” and/or straightening your photo with a plumb vertical line a snap.

A sample is displayed below:

Thirds

What you might not realize (unless you go to the trouble of using the menu command) is that overlays other than the rule of thirds are available. The following options are also available from the “Crop Guide Overlay” menu under “View”:

Cycling through the different overlays is as easy as tapping “o” on your keyboard when the crop tool is displayed (because the Golden spiral and diagonal overlays are asymmetrical, their orientation can be altered using “Shift + o”).

Although their appeal might not be felt immediately, browse through your photos with the different overlays turned on to see where these patterns shine through and to plant the seeds where they might be used in the future—some interesting compositions can be made!

Now, if only camera makers could put these in the viewfinders of their SLRs…
