Our 690 IR filter emits sufficient infrared light to create pleasing infrared images in both color and black & white — and dramatically cuts exposure times (depending on ISO, from less than one second to 2-3 seconds)
A ND filter blocks the light & less light passes through the lens. The Neutral-density filter is the first choice of landscape photographers. If you want to buy high quality Neutral density filters for photography then Singh Ray is the best manufacturer
