Thus it will take about 320 pixels per millimeter to represent what's on Velvia 50.320 pixels x 320 pixels is 0.1MP per square millimeter.35mm film is 24 x 36mm, or 864 square millimeters.To scan most of the detail on a 35mm photo, you'll need about 864 x 0.1, or 87 Megapixels.But wait: each film pixel represents true R, G and B data, not the softer Bayer interpolated data from digital camera sensors. A single-chip 87 MP digital camera still couldn't see details as fine as a piece of 35mm film.Since the lie factor factor from digital cameras is about two, you'd need a digital camera of about 87 x 2 = 175 MP to see every last detail that makes onto film.That's just 35mm film. Pros don't shoot 35mm, they usually shoot 2-1/4" or 4x5."At the same rates, 2-1/4" (56mm square) would be 313 MP, and 4x5" (95x120mm) would be 95 x 120 = 11,400 square millimeters = 1,140 MP, with no Bayer Interpolation. A digital camera with Bayer Interpolation would need to be rated at better than 2 gigapixels to see things that can be seen on a sheet of 4x5" film.</blockquote>
