Lightroom: Crop Module

The crop module. You didn't even know that it existed. Normally, you switch to the Develop module and either click on the Crop tool or R.

1. It turns out that the R is also available in the Library module. Lightroom will switch you to the Develop module and start the Crop tool. Now depending on the memory usage and what was done before, it may take a few seconds. Lightroom needs to load or to render the 1:1 preview. All images in the Develop module are always loaded as a 1:1 preview.
2. Once in the Crop tool, you can press O, the letter O to switch to the different overlays.
3. Once in the Crop tool, you can press Ctrl-Shift-R or Cmd-Shift-R to reset the crop to the original size.
4. Once in the Crop tool, you can press A to use the same Aspect Ratio for the next photo.
5. Once in the Crop tool, you can press L to turn the lights out for the background. Looks cool, no distracting background, and you can keep on using the L to return to the normal view.
