Thunderstorm pictures and hot pixels

  1. Jun 23, 2011 #1
    So the other evening, the last at Mont Cru, nature finally regaled me with a beautiful thunderstorm. So I set myself up and shot lots of 30 sec exposures during an hour of awesome display. Many pixs were useless, between nothing captured and a complete white out, but some dozen seemed very nice like this:

    But when I examined the pics more closely, I discovered a lot, maybe a dozen, hot pixels. I thought that this would be rather unacceptable for a camera like that. But after some reading like this maybe it was not that bad at all.

    So I tried that hot pixel elimunator in that link, with this result:

    The original crop on top shows three hot pixels, from left to right a blue, red, and white one. The white light on the left is a light indeed, no hot pixel. The bottom crop after applying the eliminator, only shows a little bit of the red one left

    Absolutely Astronuc and thanks

    Here are some of the best shots, notice that the wind created ghost images of the leaves in some of them.
