Trick Photography And Special Effects

Aperture camera

The diaphragm is a device that allows you to adjust the amount of light going through the lens of the camera at the time of release (when you press the button!). Of course, the more light comes in, the picture is more clear, the less there is, the more the picture is dark. Simply. Just twist the blow to one of the great words of the vocabulary of the photo (and we'll see a little later how to cope in practice)! The above illustration shows a diaphragm fully open, moderately open and fully closed (image Wikipedia).

The sensor is an electronic digital device that reacts under the impact of the light (the one that passes through the lens and which is "bumping" against him), transforming the luminous flux numerical coding (a computer file ). On digital cameras, the digital sensor is designed to replace film devices called silver or traditional. Trick Photography And Special Effects

Specifically, a photograph rarely incorporate one element of composition rules, in the vast majority of cases, it is the leveraging of several rules that contribute to the effect. Moreover, as in all the arts, a process can be based on playing with the limits of the rules, or their rejection. For example, one of the rules is the nude that one should avoid showing genitals simultaneously and the subject's face; Mapplethorpe sat a good part of his career on the rejection of this rule.

It involves placing the key elements of the image on the lines that separate vertical and horizontal thirds, or on the intersections between these lines. Doing so releases the topic and important elements (like the horizon) from the center of the photo. This avoids "cutting" photos, which gives an impression static and banal, a photograph made according to rule of thirds (in) is supposed to be more dynamic and gives more space to roam under.

The point of view of the lens has a very strong influence on the impression made by an image: it not only allows you to select the background, but it profoundly alters the reading.
