Photoshop Tutorial - Cropping, Levels, Image Resize, and Saving for Web

  1. Open a digital photograph with Photoshop.
  2. Using the Crop Tool, drag the crop box so that it selects only the part of the photo that you would like to keep.
    1. Note: If your photograph is crooked, hover over the corner of the crop box until you see a bent arrow. Once the bent arrow appears, you can turn the crop box until it aligns with your photo.
  3. Once your image is cropped correctly, you can adjust the Levels (value) of your photograph. You can access the Levels window by going to Image > Adjustments > Levels. (Keyboard Shortcut: Ctrl + L)
    1. Note: When adjusting the Levels, keep in mind that the goal is to give the most accurate representation of your original artwork. Do not over-adjust!
  4. After completing all adjustments, you need to Resize the Image. Access this by going to Image > Image Size. The AP College Board recommends the following file sizes:
Image size: The image sizes below are recommendations. Your image sizes may be different.
Landscape orientation:
·        Recommended maximum size: 530 x 780 pixels (7.36 x 10.83 inches)
·        Recommended minimum size: 480 x 480 pixels (6.67 x 6.67 inches)
Portrait orientation:
·        Recommended maximum size: 780 x 530 pixels (10.83 x 7.36 inches)
·        Recommended minimum size: 480 x 480 pixels (6.67 x 6.67 inches)

Maximum file size: 3.0 MB per image. (Your image files will likely be considerably smaller than 3.0 MB.)



    5. To Save for Web, go to File > Save As.
    1. The edited file needs to be saved as a Jpeg.
    2. Save the new edited photo with the extension “web” on the file name (i.e. IMG_2543.jpg becomes IMG_2543web.jpg). Always keep your original file!
