These are interesting articles for people who want to understand this stuff better:
RAW is not Raw
Why ISO Isn't ISO
Sense and Sensitivity
Sensitivity (ISO) in digital imaging seems to be the subject of quite a lot of confusion - it's becoming common to hear talk of manufacturers 'cheating with ISO.' So we thought it made sense look at why sensitivity appears hard to pin down, why we use the definition we do and how it's actually not as complicated as it can sometimes seem.
Good stuff that is worth reading. Self education never ends.
