My wife has booked a holiday for us to Iceland for out 10th wedding anniversary next May - as it's a place we both want to visit - and as there will be lots of photo opportunities for me (including the Northern Lights).
I've not seen the details of the trip, but it will involve a range of unusual scenery - such as Glaciers, Lava Flows and The Northern Lights.
I'm fairly excited at the prospect, and there will be a pro photographer on hand for at least part of the trip to offfer help and advice, but would prefer to get advice before I leave where possible.
In particular, are there any particular bits of kit that would make life easier?
EG: CPL, 10 Stop ND ?
(I have a Lee holder, WA adaptor for my 24-70, 1, 2 & 4 stop ND, 0.6 Hard & Soft Grads.)
