You’ll use the Ruler tool to straighten the image, which was scanned at an angle. Then, you’ll use the Crop tool to trim and scale the photograph so that it fits the space designed for it. You can use either the Crop tool or the Crop command to crop an image. Both methods permanently delete all the pixels outside the crop selection area.
- In the Tools panel, select the Ruler tool (
), hidden behind the Eyedropper tool (
).
- With the Ruler tool, click on the upper-left corner of the photo, where it meets the white space. Drag the tool to the upper-right corner of the photo, and click again.
- Click the Straighten button in the options bar (at the top of the work area).
Photoshop straightens the photograph.
- In the Tools panel, select the Crop tool (
). Then, in the options bar, enter the dimensions (in inches) of the finished image. For Width, type 3.5 in, and for Height type 2.5 in.
- Draw a crop marquee around the image. Don’t worry about which part of the image is included, because you’ll adjust the marquee
in a moment. As you drag, the marquee retains the same proportion as the dimensions you specified for the target size (3.5
× 2.5 inches).
When you release the mouse button, a cropping shield covers the area outside the cropping selection, and the options bar displays choices about the cropping shield.
- Place the pointer inside the crop marquee, and drag the marquee until it contains the portion of the picture you want shown to produce an artistically pleasing result. If you need to adjust the size of the marquee, drag one of the corner handles. You can also use the arrow keys on the keyboard to adjust the marquee in 1-pixel increments.
- Press Enter or Return. The image is now cropped, and the cropped image now fills the image window, straightened, sized, and cropped according to your specifications.
- Choose File > Save to save your work.
