I'll probably expose myself as a hack photographer, but I've always liked AA's work. I don't attempt to recreate his "style" or subject matter, but I do appreciate his results. I'm also a fan of Galen Rowell's work. AA for B&W and GR for color. GR gets criticism for his use of filters, but that's what I love about his work.
Interesting tidbit about GR and my VERY tenuous connection to him... I was flipping through a coffee table book of his work a couple years ago and came across a picture he took in Mexico years prior. I'm looking at the photograph and it looks very familiar even though I can't recall ever seeing it before. Then it hit me. I took the book into the bedroom and compared the pic to the nearly identical one on the wall, taken on my honeymoon 3 years earlier. At the time I took the picture, I had never even heard of GR other than his column in Outdoor Photography. I certainly hadn't seen the picture before. I was merely grabbing "interesting" shots while on our honeymoon. The only difference between the tow pics was the lighting (bright sunny day in mine, slightly overcast in his) and composition due to different focal length lenses. Otherwise, the composition is the same, the subject is in the same position of the frame, etc. While I never try to recreate others' works, I was pleased I looked at the same scene as GR and came up with roughly the same photograph.
