Light and Depth of Field
by: Jakob Jelling
With such a fantastic device as the digital camera for the recreation of magic in arts, a lot of care needs to be taken so as to maintain the perfection of the end product. This perfection is not only obtained by the artistic feeling of the photographer but also with the intricate knowledge of every minute aspect of the medium of creation of art (in this case the digital camera). And these minute aspects play a vast role in defining the ultimate perfection. The digital camera, light and depth of field are one such factor that would come into light in this subsequent discussion. Basically, the depth of field is a measurement of the acceptable sharpness. Yet this is very strictly a personal preference, and varies from person to person. Thus to be more formal, the depth of field can be defined as the area inside an image that demonstrates an ample sharpness that can be considered more or less in focus. So the depth of field is the range of distance, measured along the lens axis, as per which the image is caused to be sufficiently well and sharp in the photograph. The rest is as follows!
The depth of field defines the zone where all elements show clearly from foreground to background. Three factors control the depth of field in an image, they are the distance of the subject, the focal length, and the aperture used to capture the photograph. For people using compact digital cameras, one of the subjects of out of the ordinary interest is the depth of field because depth of field is more easily said than done to control with a compact digital camera than with earlier conventional analog film cameras. The minute imaging sensors of compact cameras need the use of short focal lengths, and this in sequence gives these compact digital cameras an extraordinarily long depth of field when compared to other cameras. Thereby, with intent obtaining a shallow depth of field is more complicated.
Considering a general acceptable fact, the depth of field decreases, as the image gets nearer to the camera. This means that as the focal point reaches closer to the lens, the achievable scope of the depth of field ebbs. On the other side, if the image is far enough distant from the camera, and for digital cameras, this must not be very far, the depth of field approaches out to infinity. Another important point to be noted is that the depth of field is proportional to the lens opening.
Having discussed the above important aspects of the light and depth of field of a digital camera, it is clear that the minute details make such great subjects whose knowledge becomes equally important for making appropriate use of the fantastic device, the digital camera! And the digital camera, light and depth of field comes out to be such important factors that can make all the difference if a photographer remains oblivious about this knowledge. A small factor thus can meal a big divergence!
