Camera History

11.     The effect came to be known as the "camera obscura" which is Latin for "dark room". This was the first camera. The hole acted like a lens, focusing and projecting light onto the wall of the dark chamber.

22.     Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.

33.     He added *film* to create the first successful photograph, and the modern camera was born:

A glass lens, a dark box, and film.

44.     Light passes through the lens, into the camera, and exposes the film.

55.     digital cameras capture the images with an electronic sensor called a CCD

66.     program mode you control flash and a few other camera setting and auto mode will completely control flash and exposure

77.     To attempt to blur out the background, camera will try to use the fastest available lens setting (aperture).

88.     To freeze motion, camera will use the highest shutter speed possible.

99.     The "half-pressed" button is helpful in many ways, including: faster camera response time, more control over focus, encourages better composition

110. Disable Flash no flash. There are many cases where you may not want flash at all. The mood of the photograph can sometimes be more dramatic when the natural light is used.

111. Auto-Flash In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.

112. Too much light and the picture will be washed out.

113. Not enough light and the picture will be too dark.

114. "stop" is used in every aspect of photography to represent a relative change in the brightness of light.

115.  1

116.  2

117. Longer shutter speeds = more light

118. shorter shutter speeds = less light

119. The aperture controls the opening of the camera

220. By adjusting the aperture to have a larger opening for more light
