A few of these parameters are not only important for photographers but also for analog photo scanning. These manufactures offer films with varying exposure sensibility (ISO/ASA), granularity, resolution and orange masking. 35mm Film is available from manufacturers such as Agfa, Fuji, Ilford, Kodak and Rollei to name a few. We will cover these specifics in detail.Īs mentioned at the beginning, negative film is currently very popular among analog photographers. Besides the fact that black and white film is developed into a positive via tonal correction, there are several other key factors that differentiate black and white from color film. Negatives are available in both black and white and color. On the market, middle format film has the designation 120, a designation given to the film by Kodak.
The 6 x 7cm format is often considered an ideal format due to its appropriate size, fitting to most paper formats. Other common formats are 4.5 x 6cm, 6 x 6cm, 6 x 7cm, 6 x 9cm and are commonly referred to as middle format. Digital camera image sensors with a size of 24mm x 36mm are referred to as full format sensors. The format of 24mm (height) x 36 mm (length) for an image is designated as the normal format and has remained unchanged to this day. The film is, including perforation on both sides, altogether 35mm high and depending on photo quantity (12, 24 or 36) can reach a length of 1.6m. In the middle of the 1930’s, 35mm film was also given the designation “135”. The most common size is the 35mm film cartridge. The development of negative film generates the actual color tone of the image the image transfers from a negative to a positive. Negative film is a photo material that, after development, displays the opposite color tone.
