The "high dynamic range" refers to the input range, not the output range, so it isn't a misnomer as you suggest. This also what separates it a bit from techniques like masking which don't change the underlying range available, but rather tweaking the exposure in an area. Dodging and burning are dark room techniques, which is a whole different kettle of fish. As you note though, people used to do similar things with exposure bracketing in analog days - it's just a lot easier with digital. Fundamentally you can get some pretty similar results with selective lighting. After all you are locally changing the effective represented photon density hitting your receptor, either way. |

Just saying HDR should refer to the process. The output photo, as you say, only has a normal dynamic range, compressed from the inputs.
