I would like to ask a noob question, doesn't seem to be that mentioned in the 25 pages.
For the sunrise / sunset, will a ND or GND filter be preferred. Or it depends on the blue hour or contrast to the foreground ?
If I only have a choice due to budget contraint / splitting resources, would the ND filters be suffice ? Looking in getting a new brand that has quite a good review.
I'm still venturing into difference type of photography.
ND and GND does different things. Understand what you are trying to achieve first, then get the appropriate filter. If you do not understand what each does, it is time to re-read each section about ND and GND.
