The Z-Pro 006 Yellow-Green Resin Filter from Cokin is designed to create more contrast in black-and-white images. It is optimal for landscape and portrait photography because it lightens greens and darkens reds. Therefore, this filter makes foliage appear brighter and creates separation between the dark and light tones. Skin tones are lightened as well, which makes it a very popular filter for portraiture.
The filter is square in shape and it's width is 100mm, which makes it only compatible with the Z-Pro Series Filter Holder. The filter has a filter factor of 1.5, so the exposure should be increased by 2/3 of a stop to compensate. CR39 Resin was used to create the filter.
