Silberra PAN50 is a panchromatic black and white negative film, with ISO 50. It is extremely superfine grain and has a wide tonal range. It has perfect sharpness and increased contrast is typical for Silberra PAN50 film. This film series is perfect for use in street photography, portrait photography, landscape and architectural photography. Special features of 2-layer emulsion make this film ideal to use at dusk/dawn, in winter and at complicated lighting ambience.
Silberra PAN films are optimal for use in natural light. Using the film in artificial light is subject to preliminary tests due to high red sensitivity and near-IR light spectrum. We recommend shooting several frames and processing those prior to any professional photo sessions in studios. Choosing the color temperature of artificial light sources and their power is vital to obtain predictably perfect results. This film is able to provide an excellent image in cloudy weather. The final image will have perfect shadow details preserving the overall high resolution (290 lines/mm at 1000:1 TOC contrast).
The exposure range for Silberra PAN films is 50 and 80 ISO. Lowering the sensitivity below 25 may cause loss of reasonable contrast, while increasing the sensitivity over 80 could increase the graininess and noise level.
Using yellow filters provides increased contrast and lowers the overall sensitivity of emulsion. Using the filters you shall bear in mind the next exposition multipliers (besides the coefficient of the filter itself):
Yellow filter – 1.5
Dark yellow/ orange filter – 1.8
Red filter – 2 or 3 depending on the wavelength of the filter
Low noise, low fog level and extremely fine grain
- extremely high resolution and ideal sharpness of the image;
- ability to provide superior detail level through the whole tonal range;
- higher sensitivity for near-IR spectrum of light, which not only provides you near IR-effects when shooting landscapes, but it offers you higher details in twilights or while shooting the scenes with insufficient light level
Silberra PAN films have a special anti-curling layer, which makes drying much easier (there is no need in additional weights or clips on the bottom of the stripe when drying: the film won’t curl);
The emulsion is coated upon clear polyester base which offers ultimate stability of the material and perfect optical properties; thickness of the substrate is 0.1 mm and it has excellent antihalo layer on the outer side to grant you an excellent sharpness of the image;
Special formulae of the polyester base and protective layers provide scratch resistance, prevent water traces and offer in-built anti-static properties, which makes any Silberra PAN film very convenient for hybrid and classic processing.
Depending on the specific developer the developing process can infuse the final image to feature adamant gloss within bright areas accompanied by highly detailed shadows, or make the final image reasonably even along the whole light spectrum.
Archival capacity of Silberra PAN50 is not confirmed; the guaranteed archival storage period thus is stated as over 10 years without image quality loss. Silberra recommends archival storage using special archival film sleeves (triacetate). In cold (below 20 degrees Celsius), dry and cool places.
