Time-Lapse Photography – First Experiment

Few weeks ago I have ordered intervalometer for my camera to try my hand at time-lapse photography. As is the case with most photographers that try this technique for their very first time, my first subject was moving clouds. I tried straight time-lapse and HDR time-lapse and was blown away how dramatic HDR sequence was! On second look I have realised how often I have seen HDR time-lapse clouds on television, especially in opening scenes for a golf tournaments. People that do not know about HDR photography just see great looking dramatic images without realising that there is quite a bit of computer “magic” involved. Photographers that are familiar with High Dynamic Range technique know how much work and especially time it takes to come up with a 10 seconds long sequence. Every HDR frame takes 3 images (normal, underexposed and overexposed frames) and every second of movie takes 24 frames.
24 x 3 x 10 seconds = 720 exposures. Yes, 720 photos for 10 seconds “long” movie.
