One of my favorite technical exercises with film photography was reading
the film's (or paper's) gamma and replotting how certain exposure and developing
systems could adjust it.
Similar
control is available to digital imagers. In your camera's tech specs is
the dynamic range of the sensor at different ISOs. Raw and JPEG. You may have to go
onto a tech support web site (fan based or manufacturer) to get some of
the info. As many variables exist in digital as in film. Just different
ways to express them.
An
understanding of what your camera equipment is doing is essential to
being able to craft the specifics of your photographic vision. Thankfully,
today's processes make it pretty easy to accomplish this.
Here are some nice resources:
