The SRB Green Black & White Filter is used in Black and White photography to darken orange and red objects and lighten green objects while helping contrast for fields, trees etc, by lightening foliage.
A Black and White Filter ads a whole new dimension to black and white photography with coloured filters that control the reproduction of colours in terms of grey.
This Green filter slightly absorbs UV rays and helps achieve a cloud effect.
For portrait photography this filter darkens suntanned skin, while exaggerating freckles and skin blemishes.
