Oh, my title!
I meant graduated ND filter. For afternoon sunlight shots, if I want bright sky and clean
mountains, do I take ND2 or ND4?
Is this correct?
ND2 - 1 stop,
ND4 - 2 stops

Regarding handling of Cokins, is the filter position adjustable? My horizon may be 1/3, 1/2. or even 2/3. Does Cokin holder take this into account?
How are filters stored? My bag is small and might twist and turn during travel. Glasses can not bend so likely to break.
