The other day I got the urge to try out a time lapse video with my Canon G15. I am going on a trip and wanted to try a couple of these before I did so in a far off location. For the most part it worked well except that I needed a graduated neutral density filter to knock down the sky. It probably could have used a .6 or .9 to take the sky down so it would have been close to what was in the foreground. When I start doing these with my larger cameras I will be sure to use a GND to knock down the sky. Even a colored GND would help a bit. So here are the specifics as to how I made this video. Everything on the camera was set to manual - WB, focus, exp. I did not want any flickering going on at all which would have happened if the white balance or exposure was on auto. The video was made over a period of 30 minutes and the external interval timer was set to make a shot every 3 sec. The exposure was 1/40 sec at f8. If you look real close you can see a white streak go across the sky at the end of the video. This is the contrail of a plane going by.
