[LargeFormat] Going on a cruise - what filters to use?

[Ole Tjugen]

Hello friends;

While I sat peacefully out here on an oilrig, my summer holiday was being 
planned for me without my knowledge...

It seems that we (Kerstin and myself) will be attending a wedding in northern 
North Norway this August. To get there, we have three alternatives: 
1) Airplane. Fast, but boring - dull view.
2) Car. 2500km each way?
3) Boat. The Coastal Steamer leaves Bergen every afternoon, arrives in 
Hammerfest 6 days later. Six days on a cruise ship though some of the best 
landscapes on Earth?

We'll probably drive one way - which way will depend on the availability of 
boat tickets - and drive the other leg. The car can be brought on the boat for 
a low price.

Now for the question: As some of you may know, I have no filters at all for LF 
photography; and I know I should have some. What would you recommend? I'll be 
using about two thirds BW and the rest slides. Quite possibly I'll also bring 
some IR film. Lenses are Angulon 90/6.8,Zeiss Planar 135/3.5 (dinged front), 
APO-Lanthar 150/4.5, Xenar 210/4.5, Tele-Xenar 360/5.6 (dinged front). 
Screw-on filters are not an option.

My immediate thoughts are: 
Nd grad 0.6 hard, 0.9 soft
Polariser
Yellow
Orange
ND 0.9 (for DOF control)
Red - possibly dark red (for IR and BW)
Blue - or maybe orthocromatic film?


All suggestions welcome...
