I just can't imagine the medium without his collection of work. I think he was the ultimate combination of dedication and artistic execution. I look to the man, and his work as an inspiration. Whether people admire him or not, one thing can not be argued- That is he completely achieved his photographic vision. Think about that. It's hard to imagine I could ever come close to such an accomplishment, but knowing someone else has gives me added confidence in my own work.
I think it's very interesting that you mention Tom Till. I first saw his images a long time ago, but never expected him to be listed as somebody's favorite photographer, because he isn't as well-known as many others are.
Based on my interest in lifestyle (magazine) photography, I'd say that Sang An is one of my current favorites. This is so because he regularly bases his exposures on the shadows (more so than other photographers do), and because his compositions are more abstract than those of some other photographers. I think that these things create images that are more idyllic than those of other photographers.
Most of Tom Till's stuff looks very real, and shot on Velvia film, and caught at a great moment of light. I don't know about the flowers, but I've got many examples of Velvia's high contrast bringing up the luminosity of the bright petals by darkening the green foliage. Some of his stuff looks like a warming filter was used, but the colors don't appear pumped-up beyond what Velvia did.
