The Cokin A198 effect filter allows you to simulate the sunset effect in a photo.You don't have to wait until evening.It is an orange filter with an appropriate shade, in which half the filter is stronger in color (serves to tint a brighter sky) than the other (gives a warm tint to the rest of the frame).The sunset filter 2 is a more powerful version of the sunset filter 1 (A197).Cokin filters are mounted using a holder (holder), which is attached to replaceable mounting adapters, with diameters that can be adapted to your lens.System A (size S) is recommended for use with compact cameras with lens filters or amateur video cameras.
