Photography

Photography is the process, activity and art of creating still or moving images by recording radiation on a sensitive medium, such as photographic paper or a electronic sensor. Light patterns reflected or emitted from objects activate a sensitive chemical or electronic sensor during a timed exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically. Photography has many different uses such as Business, science art and pleasure.

Genres of Photography
Aerial, black and white, commercial, documentary, fashion, fine art, forensic, glamour, high speed, illustration, landscape, native, paparazzi, photo journalism, portrait, still life, stock, under water and wedding.

Camera
Is a device that records images, either as a still or moving images known as videos or movies. The term comes from camera obscura (Latin for “dark chamber”) an early mechanism of projecting images where an entire room functioned as a real time imaging system; the modern camera evolved from the camera obscura.

Shutter
In photography, a shutter is a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture a permanent image of a scene.

Shutter Speed
B-bulb means that it is open for more than a second, the next are fractions of a second, 2, 4, 8, 15, 30, 60, 125, 250, 500, 1000. the last two fractions are for cutting the amount of blur.

Aperture
In optics a Aperture is a hole or an opening in which light travels through. In photography this can be measured in increments called f-stops.

Lens
The lens of a camera captures the light of a subject and puts it in focus on the film.

Exposure Control
The size of the aperture and the brightness of the scene controls the amount of light that enters the camera during a period of time, and the shutter controls the length of time that light hits the recorded surface. Equivalent exposure can be made with a larger aperture and a faster shutter speed or a corresponding smaller aperture and with the shutter speed slowed down.

One of the tasks which we had to do was to make a pin hole camera and to take some photos here is how the pin hole camera worked and how i made it:

When taking these photo's i used photographic paper, the photographic paper is sensitive to light and in theory is someone is in a very dark room and has a small hole in the wall this will use the light from outside the room to be projected onto the wall into the room. We used the same principle when taking these photos we got a box and then painted the inside of it black, some people used pringles boxes i used a shoe box. once we had painted the inside black we got a knife and cut a hole in the middle of the box, once we had done this we got given a piece of foil and this would act as the lens. Then finally we got a pin and pierced a hole through the foil this would then be projected onto some photographic paper which would capture the light. we then took the photographic paper to the dark room and in there we put it into some developer liquid which made the image print out then we put in another liquid which stopped it from developing to much so that the image would just be a black piece of paper then we dried it off. later we put them into photoshop on the computer and edited them and the pictures below are the final project.

Health and Safety

Cables- The reason why this is dangerous is because if you enter the room and it is dark you will not be able to see anything and could therefore trip over the wires.Lights- You must be careful with the lights as they get very hot and also they are very bright and could blind you.

Backdrops- The back drops are very heavy and could crush you so be careful or have a member of staff help you in moving them.

Coats/Bags- Put your coast and bags in the corner so you don’t tri-p over them.

Food/Drink- No food or drink as it can damage the equipment or worse break them completely.

Sensible Behaviour!

Wet and Dry areas- There are 2 areas in the dark room a wet and a dry area, these 2 areas must never come in contact.

Chemical Spills- Alert a tutor or an adult as soon as you can
