I'm going on holiday to Hawaii in November and would like to take some photography that will require an ND filter. Following the holiday it'll mostly be used for photography around the UK with maybe a bit of sunnier climes for two weeks each year.
Research has suggested that a variable ND filter isn't the right solution unless I want to pay a lot of money so I need to look at a fixed one.
Given that my bank balance cannot take an immediate hit on a range of ND filters, I need to pick one that will do the job - and accept whatever limitations that puts on my photography.
If you had to purchase only one ND filter, what stop would you get?
Bonus point: If I could get two, what should the second one be?
Common suggestions I've found whilst Googling are 2 stop, 3 stop or 10 stop. Some people say that 10 stop is very niche, some people suggest you'll get nothing from a 2 stop.
My holiday is a once in a lifetime trip, so I won't be able to determine what filters I need and then come back again. Although I know it'll be scenery, sunsets and waterfalls, I cannot really go beyond that right now having never been. I do know that if I don't have one, there will probably be several photo opportunities that I'll miss out on.
