Explanation of Terms
AF/AE Lock: On the FinePix S1 Pro, pressing the shutter button halfway locks the
focus and exposure settings (AF/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.
Auto Power Off Function:
If the camera is not used in any way for a set period, the Auto Power
Off function switches the camera off to prevent battery depletion and
to avoid wasting power when the camera is connected to the AC
power adapter. On this camera, the period can be set to either 2
minutes or 5 minutes.
• The Auto Power Off function does not operate during automatic
playback, when a USB connection is being used, or when the Auto
Power Off function is switched off during setup.
Color Temperature: There is a set relationship between the surface temperature of a
substance such as coal and the color of the reflected light.
Substances with low color temperatures reflect a reddish light, while
substances with high color temperatures reflect light in which blue
tones are stronger. The color of the light for these temperatures is
expressed as a color temperature (K = Kelvin). The light of the sun at
midday in a completely clear sky is taken to be 5500K.
EV: A number that denotes exposure. 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.
The EV number increases by 1 if the amount of light hitting the CCD
doubles and decreases by 1 if the amount of light halves.
JPEG: Acronym for the Joint Photographic Experts Group.
JPEG is a file format for the compression and storage of color
images. The compression ratio can be selected, but the higher the
compression ratio, the poorer the quality of the expanded (restored)
image.
TIFF-RGB: A format for saving image data in which a tag indicating the file
format is attached to each item of data. Files stored in this format can
be opened on a personal computer.
TIFF-YC: A storage format for image data. To open an image stored in this
format, an application that supports the TIFF-YC format is required.
We recommend the FUJIFILM USB Interface Set IF-UB/S1. The size
of TIFF-YC data is 2/3 that of TIFF-RGB data.
White Balance: Regardless of the type of lighting, the human eye adapts so that a
white object still looks white. On the other hand, devices such as
digital still cameras register a white subject as white by first adjusting
their internal color balance to match the color of the ambient light
around the subject. This adjustment process is referred to as
matching the white balance. A function that automatically matches
the white balance is called an automatic white balance function.
