A film would play whether people are watching or not; this seemed right to a thin long snake far atop a tree. Its story continued when my macro lens was in action.
The effect, I know, would not be magnetic as the pictures taken were heavily cropped, though a mosquito was involved later.
But this would be dramatic if the bent proboscis of the mosquito could be visible, (ah, biting a wrong target) and best used by a storyteller.
It presence was never felt somehow, otherwise the snake would be sorry for being born without a pair of hands.
