The Marix Black and White 400 is a black and white film that is characterized by its versatility and robustness. It is ideal for shooting in difficult lighting conditions or when short exposure times are required. Its high light sensitivity of ISO 400 makes it possible to achieve sharp and detailed images even in low light.
A special feature of the Marix B&W 400 is its enormous exposure tolerance. Even with over or under exposure by up to two f-stops, it still delivers good results without having to adjust the development times. This makes it an ideal film for situations where lighting conditions are difficult to assess or change quickly.
The fine grain of the film ensures high resolution and razor-sharp images. It retains good drawing and attention to detail even in the shadow areas. The Marix 400 is therefore suitable for a wide range of subjects, from portraits and street photography to landscapes and architectural photography.
