This is something I have been wanting to film for quite a while and was in the way of an experiment. I couldn't find a spare piece of glass to film through from underneath so ended up with a section of clear plastic which I cleaned up as best I could. This was the rough and ready set up in the kitchen:
Fortunately the monitor screen on the 70D can be flipped round which enabled me to see what the camera could see without having to stand on my head. It took longer to find a snail than it did to set up and film. A few days ago, after heavy rain, I couldn't move for them covering the paths. The day I chose for the experiment was hot and I had to look under endless pots and stones before finding one.
The 70D was used to film from underneath and I used the pocket Nikon hand held to film from above:
Sparkly bits are just reflections of the lighting.
The sound track is 'Stale Mate' by Jingle Punks from the YouTube Audio Library.
When I find a piece of glass I will have another go at this as the plastic was still a bit misty which blurred the fine detail but you can see the 'foot' rippling as it moves forwards.
