There are certain features on modern digital cameras that you can live without. Two closely related features in that category are digital zoom and interpolated resolution. Both rely on the same principle, and it is definitely something better left to the editing software on your computer. When on the subject of digital cameras, interpolation is just a term for a computer’s best guess as to what should happen when you try to turn one large pixel into more than one smaller pixels. The computer (whether it’s your home PC, a dedicated graphics machine at a photo lab, or the chip in your camera) uses mathematical formulas that try to guess, based on the colors of surrounding pixels, what the new substitute pixels should look like. For example, if a series of black pixels in a line on a white background are doubled, the pixels added between the black pixels will be black, and those between the white pixels will be white.
