Experimental Photography


Here are some photo's that I've taken whilst experimenting with different camera technique.

I took a blank CD, and poured water over it and then used a macro attachment to my 50mm lens to capture the single water droplets in ultra CU. This technique, using a single light source, also allowed me to capture the reflection from the CD, which brought out a really good effect.

I also experimented with a panorama technique, which i thought was really special and very unique compared to other simple panorama shots that are normally taken.

Macro Photography

I borrowed a Macro lens from college until the 14th May, 2013. and experimented with its capabilites. This gave me another option to choose for my final project. 





here are some of the images  I shot using this lens.













Cyanotype

How to Make A Cynaotype



  • Setup a work space for treating the watercolor paper. A dark room lit with a safe light is ideal. In any event, the room should be as dim as possible and away from direct sunlight.
  • Proceed with mixing the chemical solutions. A common recipe calls for 25g ferric ammonium citrate and 100ml water in one bottle, 10g potassium ferricyanide and 100ml of water in the other bottle. Mix until the chemicals are fully dissolved. Important note: the 2 chemical solutions need to remain separate until the paper is to be treated.

  • Place equal amounts of the 2 chemical solutions into the mixing cup. Cyanotype chemicals are short-lived once mixed together, so mix only what you think you will need for your project. You can always mix a little more, but unused cyanotype mixture must be discarded.


  • Paint the chemical mixture onto the surface of the watercolor paper using the sponge or paintbrush. To avoid wasting chemicals, treat only the part of the paper where the negatives will be placed.


  • Allow the treated paper to dry thoroughly in a dark area. It is important to keep the treated paper out of light until it is time for printing.


  • Place the negative(s) on the treated paper in the darkened room. Consider placing the negative and paper in a secure-backed picture frame to hold the negative in place. Once everything is in place, cover with a light-protective cloth and carry outside




  • Place the negative and paper in direct sunlight for about 10 to 15 minutes (denser negatives might take longer).
  • Once the paper has been exposed, bring inside and place it into the plastic tray. Allow it to sit under running water for about 5 minutes.
  • Pour a cap-full of hydrogen peroxide into the water wash to get a quick preview of what your final image will look like.
  • Allow Cyanotype to dry completley.

Risk Assessment


What is risk assessment?

A risk assessment is simply a careful examination of what in your work could cause harm to people, so that you can weigh up whether you have taken enough procedures or should do more to prevent harm.

Five steps to risk assessment-

  1. Identify the hazards.
  2. Decide who may be harmed and how.
  3. Evaluate the risks and decide on precaution.
  4. Record your findings and implement them.
  5. Review your assessment and update if necessary. 
Working in a salon.

1. Identifying hazards.

Chemicals, hair dyes, hazardous solutions, tripping over cables, slipping on hair, water, spilt shampoo etc. Hot water, sharp scissors and razors 

2. Deciding who may be harmed and how.

Customers and staff being scalded from hot water, customers not given protective eye wear and gowns when using bleach, peroxide, dyes etc. Ingestion and contamination of chemicals by the public. 

3. Evaluate the risks and decide on precaution.

Good house keeping, keep hazardous chemicals locked away, provide adequate ventilation and lighting, PAT test electrical equipment annually and provide adequate training for staff.

4. Record your findings and implement them.

Keep a log of any potential hazards, if any hazards are found report the problem straight away or notify your employer as soon as possible.

5. Review your assessment and update if necessary.

Have regular checks of electrical equipment, remove any faulty equipment, have regular emergency lighting checks, keep chemicals tidy and with clearly visible labels. 

Risk assessments are important and we all do it on a daily bases when at home or at work.

Health and safety

COSHH

The control of harmful substances (COSHH) is a health and safety guideline for the protection of employees in the workplace where hazardous substances are present. As an employer you are responsible for the well being of your safety and employees, being aware of your surroundings and the various chemicals that are used and there effect on health is important. Understanding the effects of chemicals to humans can help you in the procedures you take in the event of an accident occuring

Harmful substances.

There are many substances that can be harmful to human health such as fumes, dust, chemicals such as cleaning fluids, solvents, paint and oils.

How may workers be harmed or exposed?
  • The breathing in of fumes, gases or dust.
  • Skin exposed to irritants and acidic substances.
  • Contact with the eyes.
  • Puncture of the skin.
Exposure by breathing in.

Certain substances if breathed in can attack the nose, throat and lungs and can enter other parts of the body via the blood stream, and can be seriously harmful to the human body

Exposure by skin contact.

Some substances damage the skin or pass through it entering the body damaging internal organs and bones

Exposure by swallowing.

The transfer of chemicals from the hands to the mouth caused by not washing your hands after handling chemicals.

Exposure to the eyes.

Some substances produce vapours, gases or dust particles can damage the eyes, caustic fluid splashes can damage the eyes permanently.

Exposure by skin puncture.

The risk of skin puncture from sharp knives, and needles which can cause infections or blood poisoning.

New International warning signs.


Hazard check list.

  • Does any product you use have a danger label?
  • Is the substance harmful to breath in?
  • Can the substance harm your skin?
  • Could harm come about in the way you use or produce something?
  • What are you going to do about it?
           - Use something else.
           - Use it in another safer way.
           - Control it to stop harm being caused.

Summary.

Health and safety is a very important consideration when working, especially if your working in different environments as a lot of photographers do, keeping safe and keeping your colleagues safe is vital to a safe and successful business.
