Heliopan black and white filter light red 25 diameter: 49mm (ES49)

Black and white filters can be regarded as an essential analogue photography accessory both for professional and hobby photographers. General info about black and white filters: The basic functioning of black and white filters is always the same, and is easy to explain clearly. When using black and white filters the color of the filter is brightened or strengthened, and the complementary color is darkened. As an example let's look at a cherry tree, which we photograph using a red filter. The red of the cherries is correspondingly stronger or brighter and the green of the leaves is darkened. If, on the other hand, we use a green filter the result is the exact opposite. The result would be lush green leaves and dark cherries. Yellow filter Yellow filters are a basic filter for black and white photographers, and do their best work with landscape and plant images. The images look natural and are not overly dramatic. If you want to photograph a long-distance landscape view and there is a light haze, the filter neutralizes this to let the image appear clearer.
