if you’re serious about landscape photography, you’ll need some drop-in filters. James abbott looks at some of the best filter holder options
Good filter holders come with more than one slot, allowing you to stack filters together. Three slots is the average for most holders.
With glass filters being fragile items you’ll need a filter pouch or case, preferably with enough room to fit your holder.
Keep it clean
Dust and dirt can easily build up in the slots of a filter holder. Keep it clean and your filters will slide/fit into the holder effortlessly every time.
