I was crossing Yonge St. at Queen St. when this guy rollerbladed past and started cutting through traffic stopped at the light. I swung my camera and shop him blind, like from the hip but more from chest level. Fortunately, my ISO was set to 400 and my aperture to F8, which gave me a shutter speed of 1/1250th of a second, which is about four times the speed you need to freeze everything. Considering both me and my subject were in movement, shooting with such a fast shutter speed worked out well. I recently saw a youtube video featuring another street photographer who accomplished this using somewhat different settings. Instead of shooting in aperture with a higher than needed ISO to drive up the shutter speed, he was shooting in shutter priority, set to 1/250th of a second, with his ISO set to Auto. This guarantees you a fast shutter, but the downside is your depth of field (amount of stuff in focus, i.e. focus range) will vary depending on what aperture your camera selects. In a heavily shadowed scene your camera may go for a wide aperture to allow enough light in to satisfy proper exposure, which will give you a narrow depth of field. If you’re shooting from the hip, you might end up miss-focusing on the wall behind your subject resulting in an out of focus subject. But both methods (mine and his) have their downsides.
On another note, I finally broke down and purchased Lightroom 4 yesterday. Haven’t loaded it yet but I can’t wait to try it out. Anyway, Happy Sunday and Happy Father’s Day to all you dads out there.
