On the FinePix S5100/FinePix S5500, pressing the shutter button down half way locks
the focus and exposure settings (AF and AE lock). If you want to focus on a subject that
is not centered in the frame or change the picture composition after the exposure is set,
you can obtain good results by changing the composition after the AF and AE settings
are locked.
If the camera is not used in any way for 60 seconds, this function turns features such as
the LCD monitor/viewfinder (EVF) off (sleep mode) to prevent battery depletion and the
waste of power when the AC power adapter is connected. If the camera is then left
unused for a further period, the Auto power save function turns the camera off. This
period can be set to 2 or 5 minutes on this camera.
• The Auto power off function does not operate in PC mode, during automatic playback,
or if it is disabled during setup.
Leaving an Ni-MH battery unused in storage for a long period may cause a rise in the
level of substances that inhibit current flow inside the battery and result in a dormant
battery. A battery in this state is referred to as deactivated.
Because current flow is inhibited in a deactivated Ni-MH battery, the battery's original
level of performance cannot be achieved.
Digital Print Order Format
DPOF is a format used for recording information on a storage media (image memory
card, etc.) that allows you to specify which of the frames shot using a digital camera are
to be printed and how many prints are made of each image.
A number denotes Exposure Value. The EV is determined by the brightness of the
subject and sensitivity (speed) of the film or CCD. The number is larger for bright
subjects and smaller for dark subjects. As the brightness of the subject changes, a
digital camera maintains the amount of light hitting the CCD at a constant level by
adjusting the aperture and shutter speed.
When the amount of light striking the CCD doubles, the EV increases by 1. Likewise,
when the light is halved, the EV decreases by 1.
The frame rate refers to the number of images (frames) that are photographed or played
back per second. For example, when 10 frames are continuously photographed in a 1-
second interval, the frame rate is expressed as 10 fps.
For reference, TV images are displayed at 30 fps (NTSC).
Joint Photographics Experts Group
A file format used for compressing and saving color images. The higher the compression
rate, the greater the loss of quality in the decompressed (restored) image.
If an Ni-MH battery is repeatedly charged without first being fully discharged, its perfor-
mance may drop below its original level. This is referred to as the "memory effect".
A type of AVI (Audio Video Interleave) file format that handles images and sound as a
single file. Images in the file are recorded in JPEG format. Motion JPEG can be played
back by QuickTime 3.0 or later.
A generic term for cards that meet the PC Card Standard.
A standard for PC cards determined by the PCMCIA.
Personal Computer Memory Card International Association (US).
A phenomenon specific to CCDs whereby white streaks appear on the image when there
is a very strong light source, such as the sun or reflected sunlight, in the photography
screen.
A standard format used on Windows systems for saving audio data. WAVE files have
the ".WAV" file extension and the data can be saved in either compressed or
uncompressed format. Uncompressed recording is used on this camera.
WAVE files can be played back on a PC using the following software:
Windows: MediaPlayer
Macintosh: QuickTime Player
* QuickTime 3.0 or later
Whatever the kind of the light, the human eye adapts to it so that a white object still
looks white. On the other hand, devices such as digital cameras see a white subject as
white by first adjusting the color balance to suit the color of the ambient light around the
subject. This adjustment is called matching the white balance.
Exif Print Format is a newly revised digital camera file format that contains a variety of
shooting information for optimal printing.
