Digital Library Center: Resizing Images Saved from UFDC

UFDC displays images at normal screen resolution, 72dpi; however, dpi is relative to image size. After downloading an image, it can be resized to a smaller dimension with a greater dpi. For instance, the large version of the image above is 1535x1233 pixels at 72dpi (which would be a printed size of approximately 21 x 17 inches). If it's resized without resampling to 300dpi, the image's printable size would shrink to become approximately 5 x 4 inches.

To resize an image this way, many advanced image editing programs have an "image size" menu. For instance, in Photoshop, click on "image" and then "image size."

Image Size in Photoshop

This brings up a new window with the current size information. From here, unclick the "resample image" box.

Image Size Menu

By unchecking the "resample image" box, the top dimensions become fixed. Then, the resolution can be changed. Changing it will automatically change the print size, as shown in the two images below.

The first image shows the print size without the resolution change and the second shows the print size after the resolution is increased from 72 to 300dpi.
