Auto □ Camera automatically selects all exposure settings.
Camera automatically selects aperture & shutter speed; you can choose
Program (P) corresponding ISO & exposure compensation. With some cameras, P can also acts
as hybrid of the AV & TV modes.
Aperture Priority You specify the aperture & ISO, the camera’s metering determines the
(AV) corresponding camera shutter speed
You specify the shutter speed & ISO, the camera’s metering determines the
Shutter Speed
corresponding camera aperture
Priority (TV)
You specify the aperture, shutter speed & ISO, regardless of whether these values
Manual (M) will lead to correct exposure
Useful for exposure longer than 30 seconds, you specify the aperture & ISO and
Bulb (B) shutter speed will be manually determined through a release switch or re-pressing
of shutter release button
50. Basic Zones / AUTO Modes
Portrait Mode - A side (profile) view of a HEAD. - This mode
brings subjects in the foreground into sharp focus, and may
enlist the use of a larger aperture to blur the background.
Landscape Mode - Icon: MOUNTAINS. - This mode is for
taking shots of distant objects, or wide-angle shots, and will
bring background objects more clearly into focus by setting a
smaller aperture.
Night Scene Mode - Icon containing a STAR- This mode uses
flash and a slower shutter speed to illuminate the subject and
allow more light to enter the camera
Macro Mode - Icon: FLOWER- Used for extreme close-up
shots where the camera may have trouble focusing in other
modes.
Sports / Action Mode - Icon: RUNNING PERSON- Use this
mode for shots in which there is a good amount of motion which
you want to capture without blurring.
Movie Mode: Many cameras let you record MPEG or
QuickTime videos to the same memory card storing your photos
78. Most common with a 1.5 to
1.6 crop factor.
APS C - Advanced Photo
System type-C (APS-C) is in an
image sensor format
approximately equivalent size to
the Advance Photo System
"classic" size negatives. These
negatives were 25.1 × 16.7 mm
and had an aspect ratio 3:2.
4:3 format has a crop factor of
2.0 (Olympus)
Full Frame same as 36 x 24

87. Optical aberrations occur when points of the image do not translate back
onto single points after passing through the lens, causing image
blurring, reduced contrast or misalignment of colors (chromatic aberration).
Lenses may also suffer from uneven, radially decreasing image brightness
(vignette) or distortion.

108. Lens opening 3.5 – 5.6, as 3.5 maximum opening at its shortest focal length and 5.6 on
its longest.
2.8 only – means maximum opening all length .
Minimum Focusing distance – wide angle lens has a greater minimum focusing
distance than a telephoto.
Macro lenses – has the most, in terms of minimum focusing distance
