Exposure – Geoff Lawrence
"By 'exposure' we mean the amount of light that falls onto the film, or CCD if you are using a digital camera. In modern cameras the exposure is usually set to automatic by default and, most of the time, it can be left there and will produce beautiful pictures. There are times though, when the lighting conditions are difficult or we want to produce a particular effect and it would be nice to understand what is going on 'under the hood'."

Camera Shutter Speeds and Apertures – Geoff Lawrence
"If you are photographing fast moving objects such as cars or people running you need to select fast shutter speeds to capture the sharpest picture you can. One exception to this is when you are panning the camera with the subject, the object of the exercise here is to render the subject sharply and blur the background, so a careful selection of the right shutter speed to do both is necessary."

Photography in Sunlight – Geoff Lawrence
"If you are able to choose the time of day to shoot your pictures, try to pick a time when the sun is low in the sky, either shoot in the early morning or late afternoon. Shooting pictures of people with the sun too high in the sky, tends to mean the subject's eyes will be in shadow and/or they will be squinting in the strong light, both of which tend to look horrible. A nice side effect of shooting in the early morning or late afternoon is that the colour of the light is 'warmer', reds and yellows are stronger which generally gives a more pleasing effect."

Six feet up is bad - Neil Turner and dpreview.com
"It is very easy to hold the camera to your eye and take a picture. Good photography requires us all to think about where we are taking the picture from as well as what we are taking. The best photographs are made when the photographer chooses a vantage point to suit the subject, and it is surprising how few subjects are suited by the height of a human standing at their full five to six feet. This is compounded by the fact that when someone views the image they will see pretty much what they themselves would have taken because they haven't been told about bending your knees or climbing a ladder to shoot better pictures."

What The Histogram Is
"The histogram is simply a graph that allows you to judge the brightness of an image. You can think of the area under the graph as comprising all the pixels in your captured digital image. The left side of the histogram depicts how many "dark" pixels you have captured; the right side, how many "bright" pixels you have captured."

What Is... Exposure Bracketing
"Exposure bracketing is a simple technique professional photographers use to ensure they properly expose their pictures, especially in challenging lighting situations.
When you expose for a scene, your camera's light meter will select an aperture / shutter speed combination that it believes will give a properly exposed picture.
Exposure bracketing means that you take two more pictures: one slightly under-exposed (usually by dialing in a negative exposure compensation, say -1/3EV), and the second one slightly over-exposed (usually by dialing in a positive exposure compensation, say +1/3EV), again according to your camera's light meter."
