The Basics of Photography
Photography is all about light. To let the camera "see" what you wish, you have tools controlling how much light reaches the camera sensor: the aperture and shutter speed controls. With too little light, your photo will be too dark. With too much light, it will be too bright. In both cases some details will be lost. You use aperture and shutter speed to achieve the proper exposure, while taking into account some important side-effects you should be aware about.
How smaller the hole is, the larger it is the more you will see and you will see more detail on the photo. |
