My understanding of the ISO setting on digital cameras is that, unlike film-cameras, changing the ISO does not evoke any physical change in the camera. Rather, it simply tells the camera to multiply ...
We all know that [ISO] + [shutter speed] + [aperture] = a great picture. Now, let's take two different (very!) cameras: Nikon D3100 vs Nikon D800 and set them on Aperture priority. Settings for the ...
This answer to the question about how ISO is implemented in digital cameras seems to imply that each photosite (i.e., pixel) can have its ISO set independently. If this is true, then I would think ...
Why is it that the ISO level on most digital cameras doesn't seem to go lower than ISO 80? I understand (vaguely) that the sensors adjust the gain in order to achieve the equivalent of a high ISO ...
If I change the ISO settings on my camera, obviously the gain of the system is increased, amplifying the signal from the sensor. What's not clear to me is where the amplification takes place. I see ...
What is the ISO setting on my camera? What does it represent? What should I be aware of with regards to ISO when taking photographs
