Many chain retailers such as Walgreens, Target and Walmart offer traditional prints of digital images, which can be ordered online and shipped directly to your home for as little as 9 cents per image; they also can be picked up within an hour of ordering at your local store for a slightly higher cost. If an hour is too long to wait, portable smartphone compatible printers such as the Polaroid Zip, Canon Selphy and Fujifilm Instax allow on-the-go printing directly from your device.
We have photo print with known dimensions in centimeters, printed from digital image with known dimensions in pixels. Usually, the aspect ratio of printed image is not the same as aspect ratio of digital image. The image is scaled during printing, but its aspect ratio remains constant. This leads to unwanted effects.
