Caravaggio, what do you know about him? Well I’m not for one minute going to compare myself to the Baroque master but I’ve always admired his chiarascuro technique. This simply means light and dark, or more specifically the contrast between the two. The more I learn about photography, the more I realise I don’t know, “There are more questions than answers”. Rather than frustration at not knowing some technical aspect of the camera or a compositional technique, experiment.
The beauty of always having a camera in your pocket is you can catch the changing light, or transient observed moments. Camera sensors are now pretty good in low light. The three shots above were all shot at high ISO in the dark. When first learning about photography we tend to obsess about settings and the exposure triangle. I’m not advocating ignoring this, it’s a good basis to build your photographic knowledge on. But it can lead to “freezing” and fiddling with settings rather than concentrating on composition and awareness of your surroundings. When you’re out at night a nice fast Prime lens helps, but you need to raise the ISO to freeze motion unless that’s the effect you are going for. So I will set the ISO to 3200 or 6400 open the aperture to F2 or 2.8 then check the shutter speed from there. Although it was dark I use the streetlights and car lights where I can this gives the contrasts and lets the camera focus more easily.
