Depth of Field

We have already looked at both aperture and focus, and seen how the two concepts are linked. We’ll now take a closer look at this topic and especially at something called “depth of field”. Depth of field is something that usually isn’t immediately obvious to beginner photographers, but it is an extremely powerful concept once […]

White Balance

Colour is a surprisingly complex topic in photography. Different light sources (e.g. candle light, direct sunlight, street lighting, etc) create lights of different colours. Our eyes and brain normally correct this for us so we don’t usually notice this effect (although you can think of the difference between the very harsh white or blue light […]

ISO

We have already covered two ways to control exposure – aperture and shutter speed. In this lesson we will look at a third method, ISO. This way of controlling exposure is a little bit different to the two ways we have looked at so far. Both aperture and shutter speed refer to properties of the […]

Image Noise

The electronic sensors used in digital cameras do not always record light perfectly. This can be because the sensor has been damaged in some way, or it can be simply because the light levels during the exposure are too low. A damaged sensor may introduce dark pixels that appear as a small dark dot in […]

The Histogram

It can be difficult to accurately judge whether a photograph is correctly exposed or not. This is not made any easier by the LCD screens that feature on DSLR cameras – these often do not show the image very accurately or in very good quality. Luckily there is a tool on most DSLR cameras that […]

Aperture

Light enters a camera through a small hole in the front of the camera.  The size of this hole can be controlled and is referred to as the ‘aperture’. The bigger the aperture, the bigger the hole, and the faster light can enter the lens. If we think of shutter speed as controlling the time […]

Shutter Speed

Shutter speed, or exposure duration, is quite simply the amount of time for which light is allowed to enter the camera.  When you press the button to take a photograph a ‘shutter’ at the front of the lens opens and light can enter the camera. After a set amount of time the shutter closes again […]

Focus

What is Focus? Focus is an extremely important concept in photography. A photographer can use focus to highlight certain objects in an image, to create an air of mystery, or to invoke a dream-like nature. In this lesson the basic principles of focus will be explained, and we will begin to look at ways to […]

Exposure

Fundamentally a camera is a device designed to capture and record light. One of the first steps towards better photography is learning how to control the amount of light that the camera captures.  There are two main ways to do this – one is to capture light for a longer or shorter time, and the […]
