Street photography is a much-hyped genre, but it really isn’t that difficult. All you have to do is keep your eyes open and your mind focused. It really isn’t rocket science. I will give you a case in point, although you could technically argue that it isn’t ‘street photography’ I guess. However it is photography of people taken without disturbing them at all, without them even noticing.
I was having a quiet beer with a photographer colleague and showing him the X-Pro1 because he may look to replace his Leica. He had nipped to the toilet, and I was sat twiddling my thumbs and looking around me. The pub was virtually empty apart from three people at the bar, so I just put my camera to my eye and took a picture. No flash, no focus light flashing, nothing except a decent camera and 6400iso. Nobody even noticed and yet this image has become the most viewed on my website EVER!!
For the technically minded it was shot on the Fujinon 18mm XF lens and the camera, set on auto, gave a reading of 1/80th at f2. The camera kindly balanced the light itself, and I did nothing in post-processing to alter that. The only thing I have done is a little bit of minor noise reduction in Lightroom. Really, what could be simpler?
