Great camera filter from Pixel Peeper. 84mm wide x 95mm high (same size as the popular Cokin P filters and therefore fully compatible with the relevant filter holders). Suitable for film and digital cameras. A yellow filter is ideal for black and white shots as it increases contrast without blowing out the highlights. Fantastic for vibrant landscapes. Compatible with all 84mm P size filter systems such as Cokin P, Kood etc. Made from CR39 crystal resin for superior clarity. This has the optical advantages of glass but without risk of breakage.
