Because of the non-destructive nature of Lightroom, any cropping you apply can always be removed, and your original photo brought back unscathed. Click the Crop Overlay button and then click the Clear button on the right side of the toolbar. As Figure 12 shows, the original photo returns, crooked horizon and all. If you just want to change the crop, rather than removing it altogether, click the Crop Overlay button, and the cropping border returns over the photo for easy editing. When you’re done editing the crop, press R.
