Harles,
Thank you so much for sharing your fabulous work and also for taking the time to explain your technique. I'm sure few here will have the talent, dedication or time to try this but maybe even trying a short version might be exciting.
Nice time lapse! Always wanted to do something like this but the equipement is too expensive. Did you just use the battery grip for 3-4 hours of shooting?
When Im done shooting I import to Adobe Lightroom and make color corrections or noise reduction ( if necessary) then use Quicktime Pro 7 to make a .mov file, then its off to Final Cut.
