Document Summary

Know the essential parts of a camera and some different types like fixed focus (point and shoot), through the lens auto focus with lcd screen, dslr. Light tight box lens: aperture (or stop) to control the light intensity and depth of field, shutter- to control the duration of the light falling on the on the film of imaging device (ccd) If the pinhole is large, you get large circles of confusion. If the pinhole is small you get diffraction rings. Least confusion- best focus: a stop flattens the focal field by removing rays that produce large circles of confusion on the focal plane. Is depth of field unaffected by shutter speed: shutter speed has no impact on depth of field. Lens speed- because the smallest f/ stop value is the largest opening: smaller the number, the faster the lens (ex.
