Broadband engineers running new fibre-optic cable in Carnaby Street, in London’s West End. Fellow photographer Frode Hegland is chatting with them.

This was shot on a full-spectrum camera fitted with a 550nm Candy Chrome IR filter. This is claimed to simulate the appearance of the legendary Kodak Aerochrome colour IR film. The reality is that it doesn’t really get to that output even with careful processing with LUTs and other adjustments, but it is still an extremely useful filter for anyone interested in exploring colour infrared photography and creative manipulation.

The way different objects and surfaces have responded to this filter is extraordinary. Yes, here there has been a fair bit of conscious creative adjustment when developing (anyone have a better digital-friendly word than ‘develop’?) the shot in my RAW processing software. But look at the curious pink rendering of the barriers and the girl’s trousers, the baby-blue variations on most of the other clothes, and the almost-normal orange high-vis vest! The blue plants in the window boxes towards the top of the shot are even more clear indicators that things aren’t normal here, while the entire brown-toned store front is actually a bright yellow and a mid grey in normal vision.
