The Digital Photography Book (1,2,3) by Scott Kelby
Three books written by Scott Kelby with chapters of brief, 1 page, 'how to do it' descriptions of a myriad of photographic topics like: how to shoot weddings, sports, landscapes, travel, people etc. plus gear, flash, studios, pro tips etc. Lots of succinct, quick easy to read tips to help you take better photos. Some people find his humour off-putting but it doesn't bother me. Aimed at beginner/intermediate photographers. Lots of good info.
