If you are shooting for high dynamic range photos, then your camera should be capable of providing the dynamic range necessary. But how much dynamic range is really needed?
Since the goal in photography is to capture what you see, how much dynamic range can you see? You can see a maximum of about 13 – 14 stops (13 – 14 EV) when viewing any scene. So, you would want your camera to provide something close to this if you hope to capture what you saw. But digital cameras don’t provide as much range as your eyes, and they tend to come in at around 9 EV for the JPEG files they output.
But, if you shoot in RAW, you have an advantage – the RAW files always contain more data than the JPEG files and therefore more dynamic range. Just how much more range is dependent on your camera, but in general it is about 1.0 – 1.5 EV more on the highlight end and 1.0 – 1.5 more in the shadow end, with a total not usually exceeding around 2 EV more dynamic range. Here’s a list of dynamic ranges: Continue reading
