  1. Ooh, that timelapse is well cool. Can I ask how you put the sequence of pictures together to get a movie? Quite fancy playing around with some of it and my DSLR 🙂


  2. I put them together using GIMP – made each of the original images a layer, then lined them up carefully by making the layer above negative, and moving it to the point where it overlayed the layer below most exactly.

    Of course, if I’d used a tripod the second step would have been unnecessary – I’d just have been importing the images into GIMP and then saving as a GIF straight away.


  3. Heh! Yeah, you wouldn’t want to try putting something much longer than this together without mounting your camera very carefully on a tripod… and GIF is kind of a lousy format for this, too, so GIMP’s not the ideal software to use especially for anything bigger.

    Nice to know that something so rough and ready could produce really quite satisfying results, though! 🙂


  4. wow, I think the last one is why people imagined there must be angels
    the timelapse, though cool, began to make me dizzy after a while


  5. Good post. You make some great points that most people do not fully understand.

    « With the help of the Guide I was able to identify this unusual net-like formation with some confidence as a Cirrocumulus lacunosus undulatus – that is, a collection of high, icy cloudlets forming a layer punctuated by holes – lacunas, if you like. Granted, that doesn’t tell us much of any real use, but still, it’s always nice to be able to put a name to something that’s been puzzling you. »

    I like how you explained that. Very helpful. Thanks.
