There are none. The chemicals in a roll of film are embedded in the gelatin emulsion layers (about as thick as a human hair) and do not rub off the plastic film base.
The chemicals inside a Polaroid picture, or any other instant film, are not harmful in limited amounts and are most harmful if ingested. If you get the chemicals from inside Polaroid film on your hands, immediately wash your hands with warm soap and water.
Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film.
Is Developing Film at Home Dangerous? Even though chemicals are used in the developing process, developing film at home is not dangerous. The chemicals typically used for black & white are classified as toxic but only when consumed or in come into contact with your eyes or skin.
35mm film negatives are 36x24mm, at an aspect ratio of 3:2. Soft resolution: 35mm film is a small film format with a lower resolution than other types of analog film.
It's cheaper to work on film, it's far better looking, it's the technology that's been known and understood for a hundred years, and it's extremely reliable.” – Christopher Nolan, Director of Dunkirk. “It's just like the difference with vinyl and MP3.
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a film with a film gauge of 35 mm (1.4 in) loaded into a standardized type of magazine – also referred to as a cassette or cartridge – for use in 135 film cameras.
Most developers are moderately to highly toxic by ingestion, with ingestion of less than one tablespoon of compounds such as monomethyl-p-aminophenol sulfate, hydroquinone, or pyrocatechol being possibly fatal for adults.
In general, color developers are more hazardous than black and white developers. Para-phenylene diamine, and its dimethyl and diethyl derivatives, are known to be highly toxic by skin contact and absorption, inhalation, and ingestion. They can cause very severe skin irritation, allergies and poisoning.
Developer solutions and powders are often highly alkaline and are moderately to highly toxic. They are also sources of the most common health problems in photography; skin disorders and allergies. Developers are skin and eye irritants and many are strong allergic sensitizers.
Common chemicals used as developing agents are hydroquinone, phenidone, and dimezone. The developing mix must have high acidity, so chemicals such as sodium carbonate or sodium hydroxide are often added to the mix.
Yes! 35mm is still made and is by far the most popular film format that we sell. 35mm is still made by a few of the big dogs in film such as Kodak, Ilford and Fujifilm as well as lots of lovely indie brands such as Film Washi, Dubblefilm and revolog.
Film captures images with a photochemical reaction in the emulsion when exposed to light. A "latent image" is formed on a molecular level from silver halide that is invisible to the eye but for all intensive reasons, permanent.
Cellulose nitrate film is extremely dangerous. It catches fire very easily and once alight is difficult to put out. Fires involving cellulose nitrate burn extremely quickly with a hot, intense flame and the smoke is particularly toxic, containing large quantities of poisonous gases.
Silver in photo paprer is present as chloride or bromide not as metallic silver but the processed paper contains metallic silver. Silver has been seen to be toxic ; "Toxic effects of silver have been reported primarily for the cardiovascular and hepatic systems.
Most photographs that were taken long ago can't be thrown in the regular trash bin. Photo paper contains plastics and metals, making them unsafe when mixed with other solid waste. These chemicals are also considered toxic to the environment.
There is training to ensure you have a good seal with a full face mask but this is for highly contaminated areas. If the OP is worried about inhaling "dust" a simple N95 disposable mask is sufficient when mixing powders. If the chemicals are liquid no mask of any type will offer any benefit.
Color darkroom chemicals are more toxic than black & white chemicals for you and the environment so always take precautions like wearing gloves, an apron, protective eyewear, and a mask when using color development chemistry – especially when mixing and using the open tray method of development.
In traditional film photography, chlorine chemistry is most often used. Chlorine is used in the form of silver chloride. Photographic film is the sheet of transparent film. Gelatin emulsion is coated in its one side.
Tincture of iodine was added to dilute solutions of potassium cyanide and used to remove unwanted non-image silver in photographic materials and to remove silver stains." From the George Eastman House, Notes on Photography.
Extensive use of x-ray processing chemistry on a world-wide basis has raised professional concerns regarding darkroom disease which is a term used to describe unexpected multiple symptoms attributed by radiographer to their work environment when being exposed to film processing chemicals [2-6].
Darkroom exposure to chemical agents may lead to respiratory, allergic, and nervous system disease. Psychological problems come from chaotic work organization. Digital photography may reduce the prevalence of chemical exposure, although it may increase the risk of musculoskeletal illness.
Because of this, don't ever worry that 35mm, 120 or 4 x 5" film will become unavailable in our lifetime. If anything, sheet film (4x5," 5x7," 8x10" etc.) is actually growing in popularity as new photographers who started in digital start to get serious, and jump straight to large-format.
Number of Shots per Roll
A roll of 35mm has 24-36 shots on it. A roll of 120 film has 10-15 shots, depending on the size you're shooting. With the 645 size, you have 15 shots per roll; with 6 x 6, you have 12 shots; and with 67, you only have 10 shots. That is just not many shots per roll!
In most cases, your film will not have sound attached to the video. However, a magnetic strip was created to the edge of some film where narration or music could be recorded (aka sound stripping).
