Fotga is a relatively unknown manufacturer that aims its products at the entry-level end of the market. Cash is tight for everyone right now, so when I learnt that Fotga's infrared filter boasts a rather unique ability to vary the cutoff point of infrared light between 530nm and 750nm, all for just 25 bucks, my interest was certainly piqued!
So why is this filter special, and what makes it different? Well, as an infrared filter, it blocks out certain wavelengths of visible light, and this creates an ‘infrared’ look, typically seen in contrast-heavy black-and-white images, where blue skies turn a deep black and green leaves reflect a lot of infrared light, so appear ghostly white.
