I went and bought Mike Kelley's architectural photography tutorial from fstoppers.com yesterday because I was interested in a quick run-down in the challenges, techniques and skills involved in taking professional architectural photography. Architectural and real estate photography are very different to the skills I've been developing for my portraiture. I consider it professional development to always improve my skills through practice or learning from others.
Mike Kelley is considered one of the best in this area of expertise and I found his tutorials well presented and easy to understand. I attempted the supplied tutorial file blending several layers together in Photoshop and I can see why this is a good way to work especially when you cant possibly have strobes to cover an entire house.
