WHAT DOES DSLR MEAN?DSLR stands for “Digital Single Lens Reflex”. In simple language, 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.

HOW DOES IT WORK?

UMMM, HOW DOES A DSLR WORK?DSLR working in action

LENS SIZE: 18-55MMMM= focal lengthSome lenses have a range of focal lengths, such as 18mm to 55mm, while others have a single, “fixed” focal length. We call variable focal length lenses “zoom” lenses, because you can “zoom” in or out to get closer to a subject or further away.

THE EXPOSURE TRIANGLEAperture

f stop/f numberShutterISO

APERTURE Aperture is the opening in the lens.When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in – the smaller the hole the less light.

Aperture is measured in ‘f-stops’.

THINK OF APERTURE LIKE…It is the pupil in your eye.What happens when your pupil is large?

What happens when your pupil is small?

APERTURE

Large aperture (remember it’s a smaller number) will decrease depth of field while small aperture (larger numbers) will give you larger depth of field.

F STOP/F NUMBER The size of the aperture.In early cameras aperture was adjusted by individual metal plates that had holes consisting of different diameters.

The term “stop” is still used to refer to the aperture size, and a lens is said to be stopped down when the size of the aperture is decreased.

APERTUREAperture is one of the most important aspects of photography as it directly influences the depth of field – that is, the amount of an image that is in focus.  A large depth of field (achieved by using a small aperture (large f-number)) would mean that a large distance within the scene is in focus, such as the foreground to the background of the landscape below.

An aperture of f/13 was used here to give a large depth of field, ensuring that the whole image, from the foreground grasses to the background mountains. was sharp

A large aperture of f/4.5 was used to capture this water vole, against a soft, out of focus background

SHUTTER & SHUTTER SPEEDShutter: Your camera's shutter controls how long the sensor is exposed to light. It uses a pair of 'curtains' or blinds. One opens to start the exposure, and the other is closed to end it.

Shutter Speed: The length of time that the shutter is open.

MORE ON SHUTTER SPEEDShutter speed is the length of time that your image sensor ‘sees’ the scene you’re attempting to capture.

Shutter speed is measured in seconds – or in most cases fractions of seconds. The bigger the denominator the faster the speed (ie 1/1000 is much faster than 1/30).

SHUTTER SPEED REPRESENTATIONS

ISOIn Digital Photography ISO measures the sensitivity of the image sensor.

Higher ISO settings are generally used in darker situations to get faster shutter speeds. For example an indoor sports event when you want to freeze the action in lower light. However the higher the ISO you choose the noisier shots you will get. I’ll illustrate this below with two enlargements of shots that I just took – the one on the left is taken at 100 ISO and the one of the right at 3200 ISO (click to enlarge to see the full effect).

IS ISO AN ACRONYM?No, ISO (pronounced: “eyeso”) is a word created by the International Organization for Standardization. Here is more info:
