1:Inside a completely
dark room, a tiny hole is created in one wall. Through the hole light is
focused, and the outside scene is projected (upside down) on the
opposite wall.
2:when Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses.
3: He added *film* to create the first successful photograph, and the modern camera was born.
4: they both have a glass lens, a dark box, and use film.
5:digital cameras capture the images with an electronic sensor called a CCD.
6:The camera will completely control flash and exposure. On most cameras this is labelled "auto", on others simply "A". Some cameras only have (P)rogram.
-- automatic-assist, just point and shoot. Unlike full auto mode, you can usually control flash and a few other camera settings.
7:-- To attempt to blur out the background, camera will try to use the fastest available lens setting (aperture).
8:-- To freeze motion, camera will use the highest shutter speed possible.
9:faster camera response time, more control over focus, and encourages better composition.
10:Disabled 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.
11:Auto-Flash-- In most camera modes, Auto-flash is enabled by default and will automatically fire if the camera thinks it needs more light.
12:Too much light and the picture will be washed out. Not enough light and the picture will be too dark.
13:Not enough light and the picture will be too dark.
14:A "stop" is a relative measurement of light.
15:1 "stop"
16:2 "stops"
17:Longer shutter speeds = more light
18:shorter shutter speeds = less light
19:Before light reaches film, it must pass through an opening called an "Aperture". The aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
20:larger openings = more light
