Keith Cooper is a professional in Leicester, England, specialising in architectural photography. Hus approach is severely practical.
He has a website here.
His book on tilt and shift lenses is excellent and can be obtained from different websites, depending on where you live.
Adobe has a webpage by Crosby Dove on wide-angle lenses and their use.
Keith Cooper is indeed a great resource for TS photography.
I have three or four books dealing with Architectural photography.
Follow the Sun by James Ewing is a textbook aimed at professionals but has some good solid advice on the compositional aspects of producing pictures of buildings. A good book for experienced photographers, with little padding, but the bits about things like assistants maybe does not apply to us.
Architectural Photography by Adrian Shultz is another good solid book aimed a a wider audience, but very thorough and complete, perhaps a better book than Ewing's, but the two books are complimentary to each other.
The third book I have is Photographing Buildings Inside and Out by Norman McGrath. This is an old book I bought in London back in 1988. The photography is film based, and perhaps a little dated. The photographs display a level of formal perfection and class, which is maybe missing from todays photography. He takes you through the shooting process of each picture, which is interesting.
The fourth book I have is Architectural Photography, by Norman McGrath. The less than positive reviews it got on Amazon were about right. His previous book was written for a professional readership, this one aims at the general reader, but does not really teach anything.
Then there are books that inspire.
Milano Ritratti di Fabbriche by Gabriel Basilico. This has just been reprinted, but is in Italian. Pictures of factories and other anonymous buildings, may not sound interesting, but I love this guys style. It may be possible to find a "greatest hits" collection in English. Offbeat Architectural photography.
Romanesque Architecture, Sculpture, Painting by Toman, Rolf and Gothic: Architecture, Sculpture, Painting, Ed Konemann are two huge heavy cofee table books, that have pictures of a quality that we can all aim at.
