Timelapse - Melting Ice

After intense pestering by mother, I finally decided to clean fridge. This was shot few months back. As part of process, I was taking out ice pellets from freezer. Initially I did not notice but few minutes later, hey melting ice caught my eyes :-). I deviated from cleaning and setup a timelapse show of melting ice ;-). Initially I thought of capturing melting ice timelapse from inside freezer but did not have tripod. Hence, the melting cubes were only the option. I stacked up two books on a plastic table, poured those few ice cubes on the dosa pan, adjusted the elevation and started intervalometer. Why dosa pan? That was the only black object I found. Only black objects can expose properly this colorless ice :-). After the setup, it was time to resume cleaning activity :-(.

The final result? Yes it is this timelapse :-). The notional movement was achieved using motion time lapser tool (details at the end) where in we can gradually crop the sequence of images to have moving look. The actual movement can be achieved if you own DIY slider with servo motor. I do not have one since it is expensive and this was the only trick I could get around for movement scene. Hope you enjoy the timelapse.

The mistake I did was tuning camera in Av mode (aperture priority mode). That created flickering in middle of process :-(. The environment had unchanged light and I should have shot in Manual (M mode). Nevertheless, final one also turned out to be good :-).
