Journal mburns's Journal: More on camera bit rates

For film cameras using the same film, the bit rate proportionality simplifies to the product of the aperture area and the frame area. Slower film has the higher bit rate. For digital cameras that use the same technology, the proportionality is to the product of the aperture area and the number of pixels. But smaller sensor areas can force you to take multiple exposures in order to complete the picture with the required signal to noise ratio.
