Time-Lapse Photography with Pi NoIR and Infrared Filter


A time-lapse infrared view over Hebden Bridge on a decidedly damp Saturday.

Following on from my previous two experiments with Raspberry Pi's new Pi NoIR camera — using it for nocurnal time-lapse photography and daytime still photography with filters — I'd thought I'd see how a daytime time-lapse with infrared filtering worked out.

The camera was set going early on a damp Saturday morning, just as the sun was rising and taking a photo every ~6 seconds and shot through an 850nm filter. Powered from the same 10400mAh battery pack as used previously, it ran well past the point of filling up the 32GB SD card.

Note that as with the previous time-lapse there are occasional red flashes. I can't say for certain but I have a feeling that it may be due to the red indicator LED on the camera board, and unfortunately setting disable_camera_led=1 in /boot/config.txt does not disable this with my setup.

Once again the Pi NoIR has not disappointed, despite the fact that the weather was pretty terrible for most of the day! Early on car headlights can clearly be seen dashing around in the dark. It then proceeds to be very misty until around 1:15, and at around 2:30 the cloud starts breaking up. The sun starts setting around 3:30 and then the car headlights return.

Can't you switch off the led using GPIO 5 Andrew? It certainly works on older versions of the sofware, once you've done the config.txt thing. :)
