I wrote a tutorial on Image Averaging and part of it was to do a comparison of a traditional Long Exposure
versus an Image Average shot. This was one of the 2 results. The other
can be seen here.
The tutorial takes you through what you have to do in the field as well as back at base. There is also a Photoshop script that does the image averaging calculation, sets the appropriate opacity and then merges the layers for you.
In the tradition LE shot I used a B+W 110 ND on it's own and did 2 exposures. A 4m exposure of the sky and a second 12m for the foreground.
For the IA shot I stacked my LEE's - 0.9, 0.6 covering the whole frame with the 0.3 on the sky. I then shot 16 frames, each at 12s with an additional 3s gap between exposures giving a total of around 4m.
