Timelapse from a Raspberry Pi webcam

Just a few notes on taking very large numbers of photos with a view to making timelapse videos.

I've done a few timelapse videos using my DSLR, then processing them through Lightroom and LRTimeLapse. This work well, but is quite hard work, ties up my dslr and of course uses up a lot of shutter time (since I can't do electronic shutter with the dslr).

So I thought I'd have a go at making it happen with a webcam and a raspberry pi (I already had the webcam from other PC things I'd been doing, or else I might have used a picam).

I'm using a Logitech C920 webcam and planning to take full HD sized photos.

1. Kit in use & setup
2. Taking the photos - fswebcam
3. And the answer is python and v4l2?
4. First tests to check performance.
