I have searched for information regarding these filters but am still unsure about the following as I am using a lens with a rotating front element.
When a CPL/GND filter is used, after focusing you need to rotate the filter to get the effect you want right? Do you rotate by loosening/tightening the filter (ie. rotate by unscrewing/screwing the filter)? Or is there an outer ring which the filter can freely rotate?
What is the difference between a ND2/4/8? I am referring to in general usage, for example if I am taking landscape pictures on bright sunny afternoons, which one should I use? I know it differs from person to person but just in general the advice you would give to a new photographer?
Thanks!
