The SLR Camera
Single lens reflex. DSLR is a digital camera that uses mirrors to direct light from the lens to the viewfinder, which is a hole on the back of the camera that you look through to see what you are taking a picture of. When you take a picture, the reflex mirror swings upwards, blocking the vertical pathway and letting the light directly through. Then, the shutter opens up and the light reaches the image sensor. The shutter remains open for as long as needed for the image sensor to record the image, then the shutter closes and the reflex mirror drops back to the 45 degree angle to continue redirecting the light into the viewfinder.

Shutter Speed
The shutter speed is the unit of measurement which determines how long the shutter stays open after the picture is taken. The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor. Shutter speeds are expressed in seconds or fractions of a second. For example 2, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000. Each speed increment halves the amount of light.

An artist who is well recognised for his use of shutter speeds is Philippe Halsman. Halsman began experimenting with many different shutter speeds, which resulted in the series Jump! which featured celebrities in mid-air.
In this photo, the monochrome tone draws attention away from the background and focuses more on the subject, making it fine-tuned. The process of creating this photograph was getting the subject to jump and using a high shutter speed, capturing the subject in air. The negative space defines and emphasises the subject, drawing the eye to it and creating "breathing space." This all contributes towards to a more engaging composition,

Aperture
Aperture is a device that controls the amount of light admitted through an opening. In photography and digital photography, aperture is the unit of measurement that defines the size of the opening in the lens. This can be adjusted to control the amount of light reaching the film or, more modern cameras, the digital sensor. The size of the aperture is measured in F-stop. We experimented with different apertures with with the same scene. The apertures we used were - f5, f12, f18 and f28.
The Darkroom
Darkrooms are rooms for developing photos, where normal light is excluded, to allow the processing of light sensitive photographic materials, including photographic film and photographic paper. In most darkrooms, an enlarger an optical apparatus similar to a slide projector, that projects the image of a negative onto a base, finely controls the focus, intensity and duration of light, is used for printmaking. A sheet of photographic paper is exposed to the enlarged image from the negative. Colour print paper, being sensitive to all parts of the visible spectrum, must be kept in complete darkness until the prints are properly fixed.

The Photogram
A photogram is a picture without negatives. We took ordinary everyday objects such as keys, pencils and our lanyards, and made them into photograms. We placed these objects directly onto photographic paper and then exposing it to light. The result is a negative shadow, with transparent objects appearing grey and non transparent appear white. Picasso used photograms frequently in his visual practise.
