Research the following terms

	What is it?	Why are they used in photography?
Processing Tank	This is a light-tight container used for developing film.	Developing tank allows photographic film to be developed in a daylight environment.
Processing Spool	This is done in darkness, which you load a 35mm camera film onto the spool and detach the film from the reel. You then have to load the spool into the tank and make sure the lights are switched off.	The processing spool is a container for the film whilst it is inside the processing tank which is filled with developing chemicals.
Measuring Cylinders	They measure out your chemical dilution in an accurate way and are marked with imperial and metric values.	These are for photo chemicals and fixer. They determine the exact amount that you’re using and are usually made from a clear glass.
Thermometers	This is for colour film processing which normally has dual scales from 15°C to 65°C and from 60°C to 130°C.	These are used to determine the temperature of the chemicals used to develop a 35mm camera film.

Watch the clip on how to develop 35mm film. Write down the steps: After taking your photos when you remove the film rewind it, open the film reel with a can opener and pull it apart, cut off the little end with scissors, developing reel with little prongs and fit the film holes over the two prongs, gently squeeze the film a little bit to wrap around the developing reel trying not to make any kinks, get the scissors again and clip off the end, put the developing reel into the tank and put the lid on, pour the chemical into the tank, tip it to the side to get rid of the air bubbles, turn the timer on, a 6 minute time a developing time on the particular film and chemical combination, make sure there is no air  bubbles by tipping it upside down, then agitate your film for about 5 seconds, film is no ready to go, pour out the developer chemical from the developing reel, never pour it down the drain, always recycle your chemicals, then pour stop bath into the developing reel, this is the indicator stop bath it look yellow in the video but if it is exhausted it turns purple when poured the stop bath into the developing reel, again agitate the film for about 5 – 10 seconds, once that has been done put the stop bath back out of the developing reel and then pure fixer into it, once poured in, again make sure you do your agitation, about 5 – 10 minutes later the film is fixed and once the film has finished and is washed and dried you will have some great pictures to use. What is the temperature recommended in developing film? 68 degrees is the proper temperature for developing film

Health and Safety

Using your knowledge from the previous activities, think about the different types of hazards and health and safety issues that you may encounter on shoot and during the processing stage.

Dark Room Chemicals used, keep locked away in a safe place, never set a dark room up in the kitchen (toxic chemicals used), use safety lights (red tinted lights), use tongs for all the chemical baths, any spillage clean up, wash any area that has been exposed to any chemicals.

Using Lights Trailing wires, keep liquid away from anything electrical, make sure everything is in a visual colour so you are able to see where things are in the corner of your eyes (white flooring have black legs on the lights so are able to see it clearly before a hazard happens)

Health and Safety at Work Act (1974).
·         Control of Substances Hazardous to Health (COSHH) Regulations (2002), Provision.	COSHH covers substances that are hazardous to health. Substances can take many forms and include: chemicals products containing chemicals fumes dusts vapours mists nanotechnology gases and asphyxiating gases and Biological agents (germs). If the packaging has any of the hazard symbols then it is classed as a hazardous substance. Germs that cause diseases such as leptospirosis or legionnaires disease and germs used in laboratories.

·         Use of Work Equipment Regulations (1998).	PUWER replaces the Provision and Use of Work Equipment Regulations 1992 and carries forward these existing requirements with a few changes and additions, for example the inspection of work equipment and specific new requirements for mobile work equipment. In general terms, the Regulations require that equipment provided for use at work is: ·         suitable for the intended use; ·         safe for use, maintained in a safe condition and, in certain circumstances, inspected to ensure this remains the case; ·         used only by people who have received adequate information, instruction and training; and ·      Accompanied by suitable safety measures, e.g. protective devices, markings, warnings. (http://www.hse.gov.uk/pubns/indg291.pdf)
·         Health and Safety (Display Screen Equipment) Regulations 1992.	Display Screen Equipment (DSE) is a device or equipment that has an alphanumeric or graphic display screen, regardless of the display process involved; it includes both conventional display screens and those used in emerging technologies such as laptops, touch-screens and other similar devices.
