Trying to get a handle on HDR as I have little to no experience on this topic.
Given that an images max DR is restricted by pure black at one end and white at the opposite, am I correct that putting a "scene" (by way of multiple image exposed differently) through the HDR process only results in finer levels of tone? In other words, it doesn't make the ruler any longer, it just divides the ruler into finer increments? Presumably, this is impacted by the DR of the medium (i.e. monitor, print etc) as well.
Or, if a camera sensor is capable of say, twelve stops, can HDR actually result in an image that is, say, thirteen stops (so the ruler actually lengthens)? And if this is the case, what is the limit?
Have tried reading up on this subject, but so far it's a bit unclear.
