I did a lens swap today with a video guy using a Canon 7D to shoot a New Work City kickstarter video. He needed my 17-40mm lens and offered to let me test out his 90mm tilt/shift lens. I did a shot of Grand Central Station and did a tilt/shift effect in Photoshop last month but now I had a chance to play with the real thing. I think it makes a huge difference. The bokeh of a lens in camera is way different to a gaussian blur in Photoshop. I walked around the office at lunch to experiment with the lens. It was a 90mm so I couldn’t shoot buildings using the shift to fix perspective to I played with the tilt.
