Types of photo filters

Thesis - 2 pages - Electronics, mechanics, engineering & technology

Filters come in two forms, viz. mounted glass discs which get screwed in front of the lens and plastic or glass squares that fit into filter frames and thus get attached in front of the lens. With the aid of adapter rings (also called step-down or step-up rings) filters of one diameter can be...

Different types of camera lenses

Thesis - 2 pages - Electronics, mechanics, engineering & technology

The main function of the camera lens is to focus the image sharply on the film. But they do a lot more than that: the lens aperture allows us to control the amount of light reaching the film and the depth of the field. Lenses are classified into ‘standard', ‘wide-angle' or...
