Here is a link to a photo bucket account I set up. I uploaded 4 pictures of a cloud that I worked on 2 days ago.
http://s75.photobucket.com/albums/i299/CloudBust/The pictures were taken over a 12 minute period (before, during 2x, and after). I did not make the cloud completely disappear. I had been working on clouds for about 30 minutes prior to this effort and I was ready to quit. I estimate that this cloud had a surface area about 20 times bigger than any cloud I had previously worked on. I wanted to use a big cloud so it would be visible on film. I did not know if this cloud would work. I imagine the volume of the cloud might be 50 times bigger than any cloud I had previously worked on. It also took me much longer to bust this cloud. Usually, for a small cloud, I can bust it in 10 seconds to 1 minute.
I admit the pictures could be better. I should have set up my camera on a tripod so the angle was the same every time. Also I was using the zoom, so the cloulds could be seen better and there was enough of a time delay between the pictures that the camera shut off and reset the zoom to the default (so the zoomed in area varies in the pictures). Also the photobucket system reduced the pictures from 4Mb to 350kb. It would have been better to have someone else take the pictures.
