The last meteor shot that I posted was just all of the meteors merged down without consideration to the fact that the Earth is rotating which moves the meteor's point of origin as time goes by. The result is a group of meteors that look as if they are coming down in a totally random pattern, when in fact the Perseid's originate near the part of the sky that the constellation Persius is located, thus their name.
And so, after much labor and calculation I have remade this shot and in doing so have taken into consideration the rotation of the Earth. This gives it a much more dramatic affect, especially with the stationary stars in the background.
The Process:
Please read if you are curious about how this image was made.
First, this shot was made by setting up my camera on a tripod and programming my cable release to take 360 - 30 second exposures, which is 3 hours of time lapse. After which I downloaded all of the photos and separated each shot that had a meteor. I then combined them all into layers over another 30 second exposure of Mount Hood, the lake and the sky. I then went about the painstaking task of masking out each meteor so the background would show through the layer.
Once I have separated each meteor I returned to the beginning and located the axis of rotation at the North Star and then went about rotating each layer using Andromeda (?) as a reference point of location.
After I had each meteor coming from the proper point of origin I merged them into one transparent layer and brightened them up and merged that layer down onto the bottom layer.
And this is the result. I've been working on this off and on for a week now trying to get it right.
