Resizing Pictures

Do you ever have people complain about the size of the picture you sent them in e-mail? Have you ever tried to print a picture and have it come out blurry because you had to enlarge it? If either of these situations apply to you, then you also need the ability to resize pictures.

When printing a picture it is easier to get good quality print when the camera is set to take the picture at a very high resolution. This image size is usually set with a menu on the camera. Sizes for jpeg photos include 480×640, 960×1280, 1200×1600, and 1704×2272. Pictures taken at the 480×640 size will produce acceptable 4″ x 6″ prints while a picture taken at 1200×1600 will produce an acceptable 8″ x 10″ print. Thus, taking pictures at the larger image size provides the most versatility when printing the pictures.

However, this large image size can create problems when trying to e-mail those same images – or – even when using them in presentations because of their file size. In these situations, it helps to be able to resize the image to a smaller size, i.e. to shrink it.

For those with access to Photoshop, there is an online tutorial detailing how to use Photoshop to resize images: How to Resize Images and Maintain Sharpness by Jennifer Apple. For those who do not have Photoshop, Google’s free software, Picassa also has the ability to resize. Picassa hides this feature in the Export function. The help file, How Do I Resize My Photos? details how to perform this task. When working at a computer that doesn’t have Photoshop or Picassa, the task can be accomplished for free at several online sites:
