When I first looked at taking up architectural photography as a career, it looked easy. And many people still think it is. Often I cold-call architects and interior designers, to be told 'we've got a digital camera with a wide-angle lens ourselves, thanks' or, 'one of our directors' relatives does it for us'.
There's a little more to it than that, and I'm pleased that Jeremy Segal, a Canadian architectural photographer www.jsegalphoto.com has put this up on Youtube to explain his way of doing things, and just how complex it can be to make the unprocessed image presentable, especially when the shooting circumstances are unfavourable.
Of course each of us has our own way of processing in the style we prefer, but I think this gives a pretty good idea of some of the details that need to be considered https://www.youtube.com/watch?v=1QxmhU-XxkU
