Candid portrait of a man relaxing in front of a street mural, in Tooting, South London. I was taking photos nearby and he called out and said “take my picture.” I was happy to oblige, and the second person sitting facing away quietly completes the composition.

Shot using a 720nm IR cut filter that cuts out all visible light. When shooting infrared, not all surfaces look as you might expect from their regular ‘visible light’ appearance. This applies to black and white photography (capturing only infrared light, as in this shot) as with colour infrared (capturing a mix of some visible light as well as infrared wavelengths). Here, the mural does look approximately right in monochrome, but the clothes of both people in the shot reflect a lot of infrared and so are captured as near-white.
