The Viewfinder And Lcd
We need a way to see what the image is going to look like at the time the picture is taken, and a viewfinder provides this. With most film cameras, a viewfinder is a small window you look through to see how the scene looks. You can use that view to fine-tune your composition before taking the picture. Digital cameras include a viewfinder, but they also add an LCD that can be used as a viewfinder (except on digital SLR cameras) (Figure 3.17).
