Photography
Photography is the process, activity and art of creati
ng still or moving pictures by recording radiation on a sensitive medium, such as a photographic film or on an 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 uses for business, Science, art and pleasure.

Cameras
A camera is a device that records images, either as a still photograph or as moving images known as video or movies, the term comes from camera obscurer (Latin for dark chamber), an early mechanism of projecting images where an entire room functioned as a real-time imaging system the modern camera evolver from

In photography a shutter is a device that allows lights 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
The number 1 over the number is the speed of which it shuts e.g. B-bulb 1/2, 1/4, 1/8, 1/15, 1/30.
Aperture
In optics an aperture is a hole or an opening through which light travels in photography this can be measured in incremants called f- stops.

Lens
The lens of a camera captures the light from the subject and brings it to focus on the film or detector.
Exposure Control
The Size of the aperture and the brightness of the scene controls the amount of the light that enters the camera during a period of times and the shutter controls the length of time that the light hits the recording surface. Equivalent exposures can be made with a larger aperture and a faster shutter speed or a corresponding smaller aperture and with the shutter speed slowed down.
Pin hole cameras
A pinhole camera is a very simple camera with no lens 
and a single very small aperture. Simply explained, it is a light-proof box with a small hole in one side. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box. Cameras using small apertures and the human eye in bright light both act like a pinhole camera.
The smaller the hole, the sharper the image, but the dimmer the projected image. Optimally, the size of the aperture should be 1/100 or less of the distance between it and the screen.

Health & Safety
In the studio be aware of :
*Cables, watch out for trailing wires on the floor.
*lights, make sure not to stare in to the bulb also they get very hot.
*Back drop, be aware not to step on them or trip over them.
*Coats & bags, put them away in one corner.
*No food/drink.
* sensible behaviour, make sure you act grown up.
In the dark room - be aware of:
*Coats and bags, don't leave them in the dark room.
*wet/dry area, don't put dry objects in the wet area.
*Chemical spills, be careful of chemicals because if they spill they can ruin clothes.
Bob,
ReplyDeleteYour blog looks great - with the Pinhole posts however you need to write an evaluation - including details about the process of using the camera, and how the results were affected by what you did on the day. Your images look really interesting - well done.
