[Interpolation versus enlarging analogue film] The difference is that you are enlarging true detail when you blow up a film image. Only up to the point where the negative still holds additional information and where the gear used does not go past it's limits. Blowing up a 35mm film to 4m x 6m should widely surpass said limits. Interpolation is an algorithm's best guess as to what the adjacent pixels are likely to be, True if you use a single image --- but (nitpick) if you have multiple, near-identical images, you can do, ah, interesting stuff http://auricle.dyndns.org/ALE/gallery-auto/ Note that that eats lots of CPU time for larger images. -Wolfgang |
