VMA 105: Changing the Size of an Image (Text Questions) 1.
Explain/describe the process of completing Step D (above). With the Crop tool selected, clicking and dragging the rectangular selection area indicates which part of the image you would like to retain when the Crop is executed. A set of guides dividing the crop area into horizontal and vertical thirds (for the aesthetic “Rule of Thirds” concept in visual arts) automatically tracks along with your selection area. When you are satisfied with the crop area you have selected, hitting “Return” or “Enter” will finalize the selection and apply the Crop command.
2.
Explain how to preview an image’s printed size. To change or verify print resolution, use Image > Image Size and then check the resolution values displayed in the resulting dialog box. To preview an image’s printed size, begin (but do not yet approve / hit “Print”) the Print command (Command + P). The Print dialog will show a mock-up of the image -- at current settings -- as it would appear on the current default size of print media (for example, 8.5” x 11” if that was the most recently used size).
3.
Explain how to trim an image. To trim an image, in most cases one would use the Crop tool. Click the Crop tool icon (it looks like two L-shaped brackets crossing each other). Next, drag the corners or edges of the Crop area to determine which part of the image you would like to keep. When you are satisfied with your selection, hit “Return” or “Enter” to execute the Crop.
4.
Explain the steps required to change the canvas size of an image. To change the canvas size of an image, go to Image > Canvas Size. In most cases, you’ll want to expand or contract the canvas equally in all directions, but if for some reason you need to expand only in particular directions, then change the Anchor point (diagram near the bottom of the Canvas Size dialog) and choose accordingly. Enter values for Width, or Height, or both (depending on what you’d like to change), and click “OK.”
5.
What is the purpose of the “Resample Image” checkbox in the Image Size dialog box? The “Resample Image” checkbox (if checked) tells Photoshop to change the actual number of pixels in the image to accommodate the change in image size. Resampling is a destructive edit: you will lose image quality by enabling this option. Resizing an image, on the other hand, changes the specific presentation of a printed image without removing (or adding best-guess)
information from the image. 6.
Explain how to “Crop and Straighten Photos” in Photoshop. To crop and straighten images in Photoshop, perform a Crop as you normally would (select the Crop tool, and click and drag a rectangular marquee around the part of the image you’d like to retain), but before final approval of the command (before hitting “Return” or “Enter,” click and drag in an unselected region of the image to rotate the image. When satisfied with both the crop and the chosen rotation, hit “Enter” or Command + Return.
