I had a look at it and I have to say , I got to try this at some point. I guess the result compeltely varies with how often you press the shutter release. How did you post-process them? I assume you put them onto a time line but for how many seconds did you set each image?
The amount of times you press the shutter depens on the subject, ie people are something like every 3seconds, clouds 10seconds or something like that. Its just all down to trial and error, but there is some guides on the interent.
Now I normally shoot in RAW but I didnt want to sit through 400 images (or what ever it was) so I shot in Jpeg as this was a test. I think it worked very well but I have now learned that Lightroom you can batch process so I will be looking at buying that.
As for the speed of the images I set the speed at 24fps, from what I have read 24fps is the minium as anything less tends to look a bit jumpy.
This something I also would like to try sometime. Would be interested as well on how it is done in post processing.
Its well worth a go, even out of your back window like what I did.
Anyways I did a new one last night I had a few little huccups, like battery and memory card changes and halfway through I noticed one of my tripods legs standing on a stone so its slighty wonky.
This was done at 10sec intervals by hand using an IR Remote (still need to source a intervalometer).http://youtu.be/SqmPqeqrHmI
