Thanks everyone
It's bitter sweet. I certainly wasn't looking to get a good image out of this. I was more concerned with which direction the wind was blowing. Setting up the camera was more to kill time whilst waiting to see what the fire did. Predicting more of the same tonight here. Fingers crossed it does not occur.
Chris- each frame was 30 seconds long with no delay between shots. Canon 60D with Tamron 10-24mm at 10mm. ISO 500. F/5.6. 150 images for the timelapse and about the first 60 images used for the trail image.
