Yeah, a ND filter sounds about right. So does the crosses polarisers. I like the idea of rotating one of those to vary the amount of light through depending on the subject's brightness.
I may also get myself a light blue filter just to compare, and to have handy in my filter kit. It may offer other qualities not found in the ND and polarising filters???
Definitely don't want to lose resolution due to stopping down the aperture
Thanks for all your help. Now, what's the sobbing sound? Oh yeah, that's the sound being made by my credit card
