Cropping

Sometimes just a simple crop adjustment is all that is required to make a big improvement in your image. The Crop tool is actually capable of far more than simply performing a crop. You can predefine the final dimensions and linear resolution if you want to. Here is how it works:
1. Open an image. To follow along with these steps, open and duplicate the image.

2. First prior to cropping, make sure that your original image contains enough linear resolution to support commercial printing (typically 300 ppi). You can check this via the Image Size dialog (Image --> Image Size.) At the same time you can set up that dialog to minimize the amount of interpolation that might occur during the cropping adjustment. To do this uncheck the Resample Image in the lower left corner. Then set either the Width or Height output dimensions to a value consistent with the dimension you are seeking (here 7˝ × 5.3˝). Then view the linear resolution to see if it falls within the 250–400ppi image that is acceptable for commercial printing. (Unchecking the Resample Image check box allows the linear resolution to change as you adjust the output dimensions, without interpolation.) If you need to adjust the Linear Resolution up, check the Resample Image checkbox, then choose Bicubic Smoother from the Resample Image menu, and adjust the linear resolution in 50ppi increments (the limit the impact of Photoshop’s interpolation) until it is increased into the 300ppi range. You will likely want to follow up any resampling with sharpening, but wait until you have completed your cropping to apply any sharpening. If you need to perform upsampling on a regular basis, you might consider acquiring a plug-in called Genuine Fractals from onOne Software, which uses a scaling and resampling algorithm superior to Photoshop’s bicubic interpolation.

3. Select the Crop tool (press C to activate the tool).

4. Press Return/Enter to activate the Crop tool options in the Options palette. If the palette is already open, pressing Return/Enter will highlight the first (Width) data entry field in the Options palette. If not, press Return/Enter again to highlight this first data  field. You can then press Tab or Shift+Tab to navigate through the Options palette.

5. Configure the Crop tool options as follows : Width 7˝, Height 4˝, and Resolution 300ppi. When you have completed your setup press Return/Enter again to return to the Crop tool itself.

6. Now click and drag your Crop tool across the image. Aresizable 7 × 4 proportional crop area appears as you drag (Figure 6.42). Click and drag any of the crop area handles to resize your crop area proportionally. Note: Before you click and drag, you can clear the values in Options palette fields by clicking the Clear button located on the right end of the palette.

7. When you are satisfied with your crop area, simply press Return/Enter to complete the crop.
