What is resolution?
Resolution is an indication of the quality of your photos. The higher the resolution, the clearer and more detailed your photo -- and the more options you have for printing or creating photo gifts.

Every digital image is made up of pixels, or tiny, light-sensitive squares. The number of pixels determines the resolution. The more pixels your photo has, the clearer your photo remains as you increase its size (for prints) or print it on a gift. At the same time, the greater the resolution, the more memory is required to store the image.

Most digital cameras allow you to change the resolution, so you can select the quality of your photos as you take them.

How Cropping Affects Resolution
Whenever you crop a photo, you decrease its resolution by reducing its number of pixels. While cropping a photo often makes a photo look better, cropping also affects the photo's suitability for certain sized prints or gifts.
Whenever you crop a photo with Snapfish's 'fix & enhance' tool, we'll let you know if you've cropped so far that your image is no longer suitable for the print size or gift you have selected.
