so i got the tripod yesterday, and it's the 1st one i've ever used...so my question might be stupid, but remember it's coming from a tyro here and there is no manual...
is it possible to spread the tripod legs so the overall height is low? ie, going for small macro shots?
also, what's the black bag used for? ballast for hanging from the center post hook? and what's w/ the other strap? seems to be some metal female threaded part which i can't figure out.
thanks in advance
