Is there a case for shooting at high iso in bright sunlight?
I came across a post from a Digital Bolex tech that states that "Shooting at a higher ISO means you are feeding the sensor less light. Which in turn means you have more highlight range before clipping, but this also means less shadow range before hitting the noise floor."
and similarly "When you expose for a lower ISO you feed the sensor more light. Therefore you get more detail in the shadows, but you end up losing highlight range. More light means your sensor is more likely to clip in the highlights"
It seems to me counterintuitive that one would get more detail in the highlights at a higher iSO - if the camera is set to the same exposure level. Anyone care to weigh in on this?
ps - the post was related to a firmware revision that "Switching the ISO now shifts the dynamic range of the D16 around the middle gray point. In raw at 800 ISO, Bolex Log can retain up to 6 stops of dynamic range above middle gray and 6+ stops below. Reducing ISO lowers your highlight range, but increases your shadow range and reduces the appearance of noise"
--- is this shifting on the mid point also true for blackmagic cameras?
