How does cropping differ between 4×6 and 5×7 photos?

Because 4×6 vs 5×7 have different aspect ratios, printing a 5×7 from a 4×6 image may require cropping. Important parts near the edges of a 4×6 photo could be trimmed in a 5×7 format. That’s why it's important to compose shots with extra margin or check crop previews when printing. Planning ahead helps ensure no key details get lost in resizing.
