Orange Filters (Black and White Photography)
Orange filters sit between Red and Yellow filters, giving a nice balance of each one’s properties. This makes them popular general purpose filter.
In portrait photography, an Orange filter reduces the appearance of freckles and blemishes, giving the skin a healthy, smooth look.
When photographing buildings and cityscapes, they give bricks a pleasing tone, and increase contrast between different materials to add depth and texture to the image.
Similar to Red filters, they can be used to reduce the appearance of fog and haze, and to darken skies and emphasise clouds.
