Dark Clouds over Port of Toronto - NEX-5N & Olympus OM 35mm f2. Click for larger.
All my pictures are shot in RAW, and naturally, in colour, but I also love black and white (technically, gray). With certain subjects, the elimination of colours seems to add more impact and power. Unfortunately for me, I am not very good at converting colour to black & white, so most of my black and white pictures are converted with pre-sets in Lightroom or filters in Photoshop with some slight tweaks.
