Very funny John g. I agree that one needs to blend in asmuch as possible so as to not make the subjects uncomfortable in any way. Of course this is situation dependant.

Good advice from others on carrying something for on the floor shots.

What about getting some Knee pad like the ones used by cyclists or skateboaders?

Altherntively I could just use neoprene like foam and kneel on that.

any other thoughts people?
