Entropy is defined as a measure of the disorder (randomness) of a system. As such it is a very basic concept which is not confined to only thermodynamic systems. Consider a jar filled with equal numbers of black and white marbles. The black marbles are at the bottom of the jar. Shake the jar and we increase the entropy since some white marbles are now where blacks were and vice versa. The order of the system has been changed.
Using statistical mechanics equations representing the three laws of thermodynamics can be derived using only pure mathematics without any reference to physical reality.
Entropy:what your darkroom looks like after various members of your family have dumped all their junk in there!:cry::w00t::crazy:
John, you have enticed a number of left brain heavyweights into what I started to understand was a seriously right brain question. I respect their intellect deeply, but their comments make my hair hurt. If you're asking whether your photographic approach is shared by others, no, I don't think it is. But, it's so you that I don't even look beyond the thumbnail to recognize a 'Nanian', and that is an indelible style that's courageous and independent whether or not I like the particular 'graph.
I don't really go all out towards entropy, but I try to allow for happy accidents. When I do Mordançage, there's definitely entropy involved.
I happen to be working on a book review article for a photo club in PA and was looking in Tao of Photography by Tom Ang - the two quotes on the page I opened to are:
Those who oppose the flow of Tao end up being called "unlucky." - Tao Te Ching
The Wise succeed without intending to do so. - Lao Tzu
I spent the first few years of photography just doing things as I felt like doing them, then spent a few years being VERY methodical. Now I'm leaning more towards in between the two approaches with some experiments just because.
Very good!
Also you might come across the term in information theory and particularly in discussions of "entropy sources" for encryption. This use is not quite the same as the use in physics that Gerald described well. Shannon wrote the seminal paper about information theory and formed an equation from probabilistic considerations that is similar to the equation for entropy in thermodynamics. There was a debate about what to call the quantity and he ended up using the term "entropy" due to the mathematical similarity, but later I think he regretted that choice because the relationship with physical entropy more form than anything else and it leads to some misleading analogies.
Apologies, since I think I skidded off the right brain topic, and whether it's chaos or luck or serendipity I like it.
For all of you A.S. Eddington fans, I've always really enjoyed the mental imagery conjured up by his entropy-related term The Arrow of Time* where an increase in chaos defines the forward direction of that metric.
And not coincidently, I think, isn't that also a nearly perfect description of John's approach to photography?
