The use of B&W photography is an effective method of presenting subjects with strong form and light values. Without the emotive effects of colour one is left with clear structure. This approach lends itself to buildings and spaces that don't rely on surface colour to make their point. It is also suits the photography of historic structures. The understanding of a building form can change considerably when colour distractions are removed. One advantage of B&W are the possibilities presented at night. The photographs embrace the full transition from inky black to light without problems associated with a colour presentation.
