| | Digital cameras vs. film, part 1 |
 | | Film responds to light with a nice "S" curve--as light intensity increases, density gradually levels off in a region known as the response "knee," which is responsible for much of the detail and beauty in the highlights of fine silver-based prints. |
 | | With a digital camera, the steps are (1) digital capture, involving filtered sensors, (2) Bayer interpolation (except for Foveon), which doesn't affect color quality, (3) Image editing (no generation loss either, but lots of potential gains), and (4) Printing using pigments or dyes. |
 | | With film the steps are (1) Exposure, using layered film, where dye-couplers determine the sensitivity of the layers, and (2) development, where the dye couplers determine the color (light absorption) of each layer. |
