Photography

Photography (of photo- and -graphy2) is the art and technique of obtaining lasting images due to the action of light.2 It is the process of projecting images and capturing them, either by means of the fixation in a medium sensitive to the light Or by conversion into electronic signals. Based on the principle of the dark camera, an image is projected by a small hole on a surface, so that the size of the image is reduced. To capture and save this image, cameras use sensitive film for analog photography, while digital photography uses CCD, CMOS and digital memories. This term serves to name both the whole process of obtaining these images and their result: the images obtained or "photographs".

Process:
Based on the principle of the dark camera, an image is projected by a small hole (pinhole photograph) or a lens or set of it (which is denominated objective), on a surface; To capture and store this image, traditional cameras use a support covered by a chemical compound sensitive to light (in most of them, photographic film), while in digital photography an image sensor is used that divides the frame into A horizontal and vertical grid of elements-capturing the light of each of them and converting them into voltage values-, which are converted into numerical values after an analog-to-digital conversion process and are subsequently transmitted to a computer embedded in the device, Which gives them a format and allows their transmission or storage in a digital medium, for subsequent printing, visualization or analysis.
