How would you describe his work?
Funnily enough it was his site that got me interested in HDR but i quickly outgrew "that look" and began searching for other way I do like some of his work, some not so much i think at risk of upsetting people i would put it into the over processed category. I do have alot of respect for trey ratcliff as he does what he enjoys, he has a huge following, he shares his knowledge some for free some paid, i have bought all his ebooks. alot of his ways and style I dont agree with but that doesn't mean i think they are wrong, they work for him they make him happy and alot of other people. I pop in on his blog from time to time to see what he is up to. I was hoping his style would evolve a bit more. His writing style is entertaining though and he has some interesting stuff on his blog.
I think this guy tony kuyper is onto a very clean method of producing HDR
http://goodlight.us/very labour intensive though but you have absolute control as opposed to the HDR sausage makers like photomatix.
I completely disagree with treys take on dslr being extinct though. I am not sure if you are familiar with his workflow but he primarily processes jpg not raw and shoots off a tripod mostly as well as travels alot so i can sort of see where he is coming from. high iso performance isnt high on his list of priorities
