There are three places that brightening can be applied:

  • With amplification between the sensor andq analog to digital conversion (e.g. Pentax *ist line)
  • By using more bits in the analosg to digital conversion than are used in raw output file then bit shifting in firmware (e.g. Pentax K10)
  • By processing the raw data either in camera or in the raw converter.

The last one uses cheaper hardware but results in loss of effective bit depth.
