Photos capture the light reflected off of whatever is in front of the camera when the shutter is pressed. This record of light allows us to examine that instant in time and space. A well-aimed and properly focused camera, letting the right amount of light in at the right time can record a photo that triggers our emotions. Photos trigger happiness and sadness, invoke nostalgia or a sense of detachment, and can inspire a sense of pride or injustice.
Every photo taken has great potential to inspire. It is the job of the photographer to design the image to inspire the intended audience. The photographer has the ability to highlight specific issues of importance to the audience.
