I am asking myself whether I need more than one ND filter for my desired areas of application, which are:
- portrait photography in (very) sunny environments (no wedding etc.; basically familiy shootings during our holidays)
- landscape photography
- softening the appearance of water (sea, river, waterfalls)
- architecture photography
- sunset and orbital photography (star trails)
and where the shooting could be at any time of the day.
I already own a Hoya hd circular polarizer that loses around 1 stop of light. However, I am quite sure that I will need at least a 10 stop filter for orbital photography. Am I correct?
If yes, would recommend to buy even more ND filters (which ones?) for the remaining areas of application or can these also be covered using the circular polarizer together with the 10-stop filter?
Thanks a lot for your suggestions!
