DynaRange

A new, modern and easy to use tool to measure camera sensor's dynamic range.

The basic usage will be as follows:

  1. Prepare the camera on a tripod to photograph a screen's monitor
  2. Display a special chart that contains patches from black to white (supplied)
  3. Take a photo of the screen at each ISO setting in RAW format
  4. Put the lens cup and take a photo at base ISO (a drak frame)
  5. Display a white screen and take a totally overexposed photo (saturation frame)
  6. Load all RAW files into DynaRange
  7. Get the measurements
