To check the infra red blocking filter of my EOS-m versus the HTC mobile phone camera
I made this triptych. The 150W floodlight is running on 30Vdc rather than 240Vac so it
has a just a warm red glow (no white light at all and plenty of infra-red. The first
picture is the glowing lamp with normal room lighting taken on the EOS-m, second picture
same lamp without room lighting and the EOS-m. This is also how I also saw the lamp.
The final picture is taken with the HTC mobile camera and the colour has changed to
purple because the HTC mobile camera does not have a decent Infra-red blocking filter.
