Hello!!! My Name is Gautam, I'm here to explain you the concept of PHOTOGRAPHY. 1. For creating PHOTOS from camera you must understand the concept of ISO, SHUTTER SPEED, APERATURE, IMPORTANCE OF LIGHT and most important is to use the camera 2. You must known your camera properly, every setting of camera, etc... 3. What is ISO? For digital photography, ISO refers to the sensitivity—the signal gain—of the camera's sensor. The ISO setting is one of three elements used to control exposure; the other two are f/stop and shutter speed. 4. What is SHUTTER SPEED? Shutter speed is a measurement of the time the shutter is open, shown in seconds or fractions of a second: 1 s, 1/2 s, 1/4 s … 1/250 s, 1/ 500 s, etc.... In other words, the faster the shutter speed the easier it is to photograph the subject without blur and “freeze” motion and the smaller the effects of camera shake. 5. What is APERATURE? Aperture refers to the opening of a lens's diaphragm through which light passes.... Lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller apertures. 6. Why it is IMPORTANT to study LIGHT? Photographic lighting is the illumination of scenes to be photographer. A photograph simply records patterns of light, color, and shade; lighting is all-important in controlling the image. Illumination is desired to give an accurate rendition of the scene.
