In lesson we made a Camera Obscura,by cutting two different holes on either side of the box, one of them 2cm and the other one the side of the box, and stuck a magnifying glass as the lens on one, and tracing paper (13cm by 13cm, with a 1cm border) to the other. We used the tracing paper to draw the image that was projected onto it through the lens.
the SLR camera
'SLR' is an abbreviation of 'single-lens reflex'. The SLR camera lens sees exactly what the photographer sees, which means they also produce high quality photos. Different lenses can be used on this camera, and they are also ideal when photographing movement.
