Resizing

‘Resizing’ and ‘resampling’ sound the same but they’re not. ‘Resizing’ an image means usually means changing the size at which it will be printed, not changing its actual pixel dimensions. So for example you can ‘resize’ a photo to print it as a 6″ x 4″ or a 12″ x 8″. The only thing that changes is the number of pixels per inch in the final print. Some programs blur the distinction between ‘resampling’ and ‘resizing’ so it’s important to make sure you understand what they’re about to do.
