This is a cool idea; I could definitely recommend quite a lot that I have seen, but I'd actually like to put forward a friend of mine for consideration, partly because he's the reason I got interested in taking photos in the first place, but mainly on account of the photos he has taken since taking up photography as a hobby a couple of years ago. He'll have been a member of PBase for a year in October, hopefully that qualifies him!

Here are a few reasosn why I'm suggesting Andy:
Firstly I think there are some good examples of architectural shots in his galleries; he has the ability to make otherwise unremarkable buildings seem imposing and striking, and I'm always impressed how he can create a sense of drama even when you're just looking at a wall or a facade, which I am sure must be hard to do.
Secondly he's got a will to experiment that I admire; I'm referring to the types of cameras he uses - anything and everything from toy cameras, Lomo all the way up to an Xpan - which makes for a good set of diverse images.
And a final reason is this photo, which he took with his Lomo:

I know you're looking for an overall body of work rather than one outstanding image, and there are plenty of great photos within his galleries as I've said. But this one...well...I've probably looked at it more than any other photo on PBase. It doesn't need me to say anything about it really, just take a look!!!
Anyway, in my humble opinion, well worth a browse.
Cheers,
Stuart
