Decreasing resolution

Downsampling decreases the resolution of an image by removing a specific number of pixels per unit of measure. This produces better results than upsampling. Best results are usually achieved when downsampling is done after correcting an image’s color and tone but before sharpening. For more information about correcting and sharpening images, see “Adjusting color and tone” on page 387 and “Retouching” on page 397.

You can change the resolution and size of an image at the same time. The center image is the original, the first image is downsampled, and the third image is upsampled.
