An Infrared Test
Got an IR filter rated 850 nm (which is quite useful for black and white infrared photography but not so much to get false colours). It cost next to nothing and the initial tests reveal it is very acceptable. Getting the focus right is a real pain, but when you get somewhere close, the filter does its job.
Shot with a Canon 60D and a Canon 50mm f1.8. Around 15 seconds of exposure at f8 and 1600 ISO. This lens works really well with IR unlike the Tamron 17-50 which would show up a hotspot as big as the aperture.
PS: This building is easily the most photographed one by me.
