Definition: A picture created by projecting an image onto a photosensitive surface such as a chemically treated plate or film, CCD receptor, etc.
Alright class, settle down and let’s take a look! Today we’re tackling the word “photograph,” a really important one for understanding how we capture memories. Now, the dictionary gives us a rather long definition – "A picture created by projecting an image onto a photosensitive surface…" – and it's true, that is what it means! But let's break it down in a way that makes sense, shall we? Think of “photo” as coming from the Greek word for light - “photos.” It all comes back to light ! A photograph is basically a picture made by light. When you take a photo with your camera, what's happening? Light bounces off whatever you’re photographing – maybe it's a smiling face, or a beautiful flower – and that light hits something special called a photosensitive surface. This could be: Film: Like old cameras used to have, where the film changes when exposed to light. A CCD Receptor: (That’s “Charged Coupled Device,” don't worry about the mouthful!) – This is what modern digital cameras use; it’s like a tiny chip that records the light. Essentially, the light changes something on this surface, creating an image - a permanent record of what was in front of you when the picture was taken! So remember: Photo = Light . It's all about capturing a moment with the power of light. Do you have any questions about that? Perhaps you’d like to share a time you took a photograph and why it was special?
