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.
