Dear all expert,

i am in india right now and would like to ask anout the CPL...
i am beginner in CPL and filter
i have a CPL, and a grey to colorless filter
can i use both to take pic same time?
the sky here is not very clean, and grey sky, very dusty
not enough light level.

and,
how to sure that i turn the correct position of CPL? just see the pic? if i take pic without any reflect shadow? how can i know?


i have not enough compact flash...

thanks
alex

仲要睇埋你支係咩鏡,太wide疊兩塊filter會黑角.
