I would like to ask all, specially the op since a forum member in other forum is claiming "captured DR is higher, the higher the ISO is" as a general rule with reference to one of the Cambridge in Colour tutorials (http://www.cambridgeincolour.com/tut...amic-range.htm).
It is well know that we can capture more DR at low ISO values when there is no aperture/shutter limitation.
It is also known that when in low light conditions we cannot increase aperture or reduce shutter speed beyond a certain limit, and we get underexposure, it is best to increase ISO in order to reduce noise.
Do you agree then with the claim: "at a given aperture/shutter more DR can be captured the higher the ISO is set?"
Shots at the same aperture/shutter in both cases:
