Photographer Nicco Valenzuela recently published a helpful "crash course" that covers everything you need to know to get started using lens filters for landscape photography. The video covers everything from the two main filter 'formats,' to the three main filter 'types,' to the various situations where you might want to use each filter for the best possible results.
NiSi has just launched the 150mm Explorer Collection of square glass filters. This new lineup of ND and Graudated ND filters promises the same professional optical quality, but uses a special hardening process to deliver twice the durability of a typical glass filter.
NiSi has unveiled a tiny new filter system for the fixed lens Fujifilm X100V, allowing X100 shooters to benefit from high-quality graduated ND filters, NDs, polarizers, the company's "Natural Night" filter, and more.
Sony has just released an interesting new app for its mirrorless and high-end compact cameras. The app, called "Digital Filter," lets you divide your sensor into up to 3 sections and capture each of those parts differently. It's like a graduated ND filter built right into your camera's software.
A few months ago, photographer Karl Taylor got a tour of the LEE filters factory where he got to see how these high quality filters are cast, tested, and dyed (by hand!)—he even got to dye one for himself. Fortunately, he took a camera man (and now us) along for the ride.
