Digital Photography Techniques

Improve With These Tips


Since the advent of the digital camera many more aspiring photographers have become interested in developing their basic photography skills: learning some of the jargon associated with this new hobby is absolutely necessary if you intend to progress beyond the very basics of turn the camera on, take aim and press the shutter.

Digital photography techniques, such as 'dynamic range', 'depth of field', and 'field of view' can all help to improve the quality of your pictures. Our eyes are much cleverer at discerning different aspects of vision than even the most expensive camera that is available to date so, to obtain a finished photograph that resembles as closely as possible what our eyes see, manual changes have to be made by the photographer, depending on the degree of light available and the distance away the object being photographed is from the camera.

Establishing a precise focal point and then maintaining that area around that focal point in clear focus involves the photographer making a decisive decision about the depth of field: the decision to be made involves keeping close to realism or being rather compliant in terms of artistic portrayal.

When staying close to realism the photographer needs to decide between the length of exposure, the depth of field and the level of film grain whereas, multiple exposures can be implemented if the photographer decides to enjoy a variable amount of artistic flexibility. They end result is a photograph that exhibits multifaceted focal points that is loosely similar in the way our eyes interpret a scene when we give a view a fleeting glance that takes in both near and far objects simultaneously.

Digital photography techniques overcome the natural drawback a camera has that our eyes can overcome, such as dynamic range. Whereas our eyes can adapt, with little problem, to changing light conditions, the photographer has to have sufficient knowledge of digital photography techniques to surmount this problem. Dynamic range accounts for discernment of details and making sense of shadows and contrasts which, by utilising a range of filters, can overcome dynamic range with evenly exposed images.

This prevents the finished photograph looking as if it has been overexposed. Field of view takes into account the wide panorama our eyes are naturally able to view in any single sight. However, the camera is dependent on lens aperture and, of course, the previously mentioned, depth of field and dynamic range.

In order for the photographer to obtain a similarly panoramic effect, other digital photography techniques need to be used - especially a technique known as digital panorama: it is also referred to as photo stitching as this better describes what it actually does. In order to obtain an enhance panorama, the photographer will aim the camera at a series of consecutive views.

A series of photos is obtained from which final picture is obtained. This is one of the more complicated digital photography techniques but the end result produces a picture that reveals better perspective and less lens distortion - essentially by matching up the individual pixels by blending the pixel seams.

The particular technique for matching up the pixels for a seamless finish is usually accomplished using software and involves isolating the vanishing point and the horizon alignment. This final stage only really requires the photographer to use the camera to take a series of still shots - the rest involves computer techniques of digital photography.
