When interlacing, we take a slices from multiple images and arrange them to fit behind the lens. In this example we take slices from 4 different images and place each in order behind the lens. The lens will then focus on each different frame as the lens or users moves. The resolution of a lenticular file is a direct result of the number of lenses per inch multiplied by the number of frames used. In this case we have 4 frames, if we have 100 lenses per inch the result will be a 400 DPI file.
