Magic Lantern Improves 5D Mark III Dynamic Range to 14 Stops

From Magic Lantern
The Magic Lantern team is letting the world know that they are at the beginning of a new function for the 5D Mark III and EOS 7D. Apparently they’ve figured out a way to boost dynamic range by 3 stops by using a new way of making a photograph by using ISO 100 for some of the vertical lines and ISO 1600 for the rest of it. Sounds wild to us, not sure how they’re doing that. There will be a process to combining the lines of 100/1600 ISO to give you the full resolution file.

  • Works for both photos and raw videos on Canon EOS 5D Mark III. On Canon EOS 7D, photo only (since it can’t do raw video).
  • What are the benefits? more dynamic range (less shadow noise).
  • The functionality was not really in Canon firmware, but in the chip that samples the sensor. Canon firmware does not make any use of it (they just set both ISO “registers” to the same value). It was implemented on the hardware side though (and that’s why it works only on these 2 cameras, because only they have two ISO amplifiers).
