However great your subject and composition, a blurred shot is usually unusable, whether the blur is caused by camera shake or focusing errors. So what’s the difference? Camera shake becomes a problem when the shutter speed is so slow that the micro-movements you make when shooting are recorded on the camera’s sensor. Even though the focus may be pin sharp, the resulting image looks blurred or smudged.
The best pictures are often about familiar themes, but how do you take a picture of a familiar theme without it looking, well, over-familiar? There are a number of techniques for this, but today we’re going to concentrate on angles. The secret of angles is that they provide a means of getting a different view on the same old stuff, therefore communicating a sense of freshness.
Taking a great landscape photograph brings a scene to life, but it’s one of the trickiest things to photograph well. You’re essentially taking a 3D vista and turning it into a 2D image, and it can be difficult to maintain the depth and clarity that your eye can see in a photograph.
Not all light is the same colour, but if you want to ensure great colour reproduction in your digital photographs, it’s necessary to appreciate the basic physics behind this phenomenon. A good place to start is with visible light. This is a stream of electromagnetic energy that is emitted when a material is heated. Most photographic light sources produce a mixture of all the visible wavelengths (that is, colours) of the electromagnetic spectrum, but the proportions of these wavelengths vary wildly from one light source to another.
One of the simplest ways of giving your portraits more impact is to vary the composition and poses you use. If you always have the person standing in the middle, your pictures are quickly going to be as predictable as another re-run of Last of the Summer Wine.
