Trial and Error- Camera angles

In order for me to shoot the tracking shot of Lilie's feet I had a lot of difficulties that I had never thought of before, when I was on location for this shot I noticed the the ground was very uneven and would cause the footage to be very shaky.  In order to resolve this problem I went to find some material to put on the ground, for this I found some corrugated cardboard, this was suitable as it is shock absorbent, which allowed for steadier footage.
After this I decided to strap the camera down on to the middle of the dolly, I did this by using masking tape for security.  I then placed the tripod on to the dolly, this made it easier for me to move the camera with Lilie's movements.
