RESUMO

Photography is progressing alongside science sisnce its invention. It can be said that the former has been conceived in the womb of the latter and since then one improves the other as both pursue development. The technological innovations of photography devices have been demanded by the science, from Biology to Physicis, from Medicine to Astronomy. However most of these innovations addresses the perifericals of the process, which have the function of refining viewing or correcting the look into the subject matter. In order words, despite whatever accessories like microscope or telescopes or whichever wavelengh of light, it all delivered the image to the dark chamber where an old fashioned photo sensitive film stood. Only recently along the last ten years has there been a new development which brings a radical new system: that of digital technology. We now are looking at a situation which the image is generated through eletronic light sensitive devices, or inside a computer or again through conventional methods but later transformed in to a eletronic signal ordered in numerical structures. Thus, digital imaging is a reality that allows an immense new freedom to work with, as opposed to the old silver grains glued to a surface....Note: The complete abstract is available with the full electronic digital thesis or dissertations
