Photo Journalism lesson notes

when using a camera the camera sees the object that you focus on upside down but due to the mirrors in the camera it refeleces it back up to your eye to show you that its the right way up and that you dont take an upside down photo the aperture can open and close to different sizes smaller or bigger hole using the smaller one doesnt let much light in but using it too big lets to much light though this is due to the light from the sun that refelecs of the object and into the camera light on travels stright also depends on the shutter time as well dependeing and what its all set to you can get blured photos or clear photo some times if the camera is focused on a object it would blur out the background.
