Now let's get back to those crop tool options and presets. If you select the crop tool and click the arrow at the far left end of the options bar, you'll get a palette of crop tool presets. These presets are for cropping to the most common photo sizes, and they all set the resolution to 300 which means your file will be resampled.
You can create your own crop tool presets and add them to the palette. I suggest you create your own crop tool presets for common photo sizes without specifying the resolution so you can quickly crop to these sizes without resampling. I'll walk you through creating the first preset, and you can create the rest on your own. Select the crop tool. In the options bar, enter these values:
- Width = 6
- Height = 4
- Resolution = (leave blank)
Click the arrow for the presets palette, then click the icon on the right to create a new preset. The name will fill in automatically based on the values you used, but you can change it if you like. I named my preset "Crop 6x4."
