I haven't had the urge to contribute to this thread, till now, because it seems fairly obvious to me that we live in a world of protection of copyright and of processes on all levels. Anyone who thinks they might have an economic advantage by exercising copyright law and/or secrecy, will often take that advantage.
That Alain Briot chooses to make his processes and techniques freely available is a great credit to him and an inspiration to us all. As a global community, we could all benefit by the adoption of such practices, also in areas other than photography.
I also understand Jack Fleshers's position, which I would describe as the more commercially oriented position of protection of processes. Perhaps it's not a co-incidence that Jack's avatar is a picture of a predator.
The article itself was interesting in the sense that it portrayed the dedication to the production of a single image. This is truly the anithesis of a snapshot in every respect.
Do most of us need to know this, as Mark suggests? Maybe not. In a month's time, I hope to return to Angkor Wat to photograph the ruins in a different light, with pools of water lying on the fallen stones and green algae prolific.
