Filter Advice

I am going on a 10 day road trip camping with my family. I want to get some polirizer filters and Neutral Density filters ( to take some sunset and sunrise pictures. I am thinking about getting one of each, one for my tamron 17-50 and one for the 70-200. Would I even need either for my 70-200? maybe a polirizer only?

Which filters to get. I have seen b+w highly rated. I have never used a ND filter, anything I should look out for. 7 stop? 10 stop? gradiated ND filter. ONe of each?

I can highly recommend B&W circular MRC polariszers - a 77mm should fit
both lenses. For sunrise/sunset you will find Graduated ND filters made by Lee or Hi-tech in 2 stop or 3 stop useful in balancing the exposure.

Just realize that a polarizer will be very little help on sunrise or sunset photos as the maximum effect of a polarizer is at right angles to the sun. A grad, maybe even a "reverse grad", will be more useful for those. Polarizers will be more generally helpful toward the middle of the day, or photographing the play of the sunrise/sunset light on the surrounding terrain.
