Getting your digital images perfectly sharp is something that most photographers want – however clean, crisp, sharp images can be difficult to achieve.
Perhaps before we start exploring how to improve sharpness it would be good to talk about the main causes for lack of sharpness:
- Poor Focus – the most obvious way to get images that are ‘un-sharp’ is through having them out of focus. This might be a result of focussing upon the wrong part of the image, being too close to your subject for the camera to focus, selecting an aperture that generates a very narrow depth of field or taking an image too quickly without checking it is in focus.
- Subject Movement – another type of ‘blur’ in shots is the result of your subject moving – this is generally related to shutter speed being too slow.
- Camera Shake – similarly you can get blur if you as the photographer generate movement while taking the image – this often relates to either shutter speed and/or the stillness of your camera.
- Noise – ‘noisy’ shots are ones that are pixelated and look like they have lots of little dots over them (get up close to your TV and you’ll get the same impact).
