Foma Ortho 400 Black and White Medium Format Film

Description

FOMA Ortho 400 is a special orthochromatically sensitized black and white negative
film. It is characterized by good resolving power and contour sharpness, fine grain
and high maximum density of the silver image. Its high optical sensitivity enables to
take photographs even in adverse light conditions and using shorter exposure times.

The nominal optical sensitivity of the film is ISO 400/27°, but its wide exposure
latitude provides very good results even when overexposed by 1.5 EV (ISO
160/23°) and underexposed by 2 EV (ISO 1600/33°). In case of exposure by lower
chromaticity temperature (2700-2400 K) than daylight is recommended moderate
adjustment of the exposure by 0,1-1 EV, especially by underexposure of the film (El
800 ISO and higher) with an absence of modification of development time (push
process). Thanks to its typical tonal character, this orthochromatic type of the film is
particularly suitable for artistically stylized portrait photography. FOMA Ortho 400
has a high level of the spectral sensitivity in green part of the visible spectrum, which
is particularly advantageous when taken photographs of the landscape motifs and
sceneries (forest greenness of the leaves of trees, bushes, etc.).

Characteristics of Orthochromatic Film

Sensitivity to Blue and Green Light: Orthochromatic film is sensitive to blue and green wavelengths of light, making it ideal for capturing natural landscapes and outdoor scenes.

Limited Sensitivity to Red Light: The film’s lack of sensitivity to red light can lead to unique renditions of skin tones, emphasizing textures and creating artistic portraits.

Contrast and Grains: Orthochromatic film is known for its distinctive contrast and grainy texture, adding depth and character to the photographs.

Artistic Expression: The limitations of orthochromatic film can encourage photographers to explore creative techniques and compositions, resulting in truly artistic images.

Tips for Using Orthochromatic Film

Choose the Right Film Type: Different orthochromatic films offer varying sensitivities and characteristics. Experiment with various film types to find the one that best suits your style and subject matter.

Master Exposure Techniques: Proper exposure is critical when using orthochromatic film. Learn to read light, shadows, and highlights to achieve the desired results.

Embrace Contrast and Texture: Emphasize contrast and grain in your compositions to add drama and depth to your black and white images.

Explore Portrait Photography: Orthochromatic film excels in capturing captivating portraits. Experiment with portrait photography to explore the unique renditions of skin tones and facial features.

Experiment with Filters: Using colored filters can further enhance the contrast and tonal range of your images, giving you more creative control over the final result.

Developing and Darkroom Printing: Consider developing your film and printing in the darkroom to fully immerse yourself in the traditional film photography experience.
