Exif (Exchangable Image File Format)

A standard digital camera file format established by the Japan Electronics and Information Technology Industries Association (JEITA).

Gradation

The total contrast range of an image. Also the range of light and dark tones in a scene that a camera sensor is capable of registering.

Histogram

A graph that shows the darkest and brightest points in an image. The horizontal axis represents the brightness and the vertical axis represents the number of pixels. This is useful when you wish to refer to the exposure status of an image.

Image Resolution

The term image resolution refers to the number of pixels in a digital photo. You can get a large picture in good condition with high-resolution.

Image Quality

Image quality is affected by the compression rate of the digital image. A high-quality photo has a low compression rate.

ISO Sensitivity

The sensitivity of the camera to light; the equivalent of film speed in a camera using film. With a high sensitivity, images can be shot with a high shutter speed even in dimly lit places, reducing camera shake. However, images with high sensitivity are more susceptible to noise.

JPEG (Joint Photographic Experts Group)

An image compression method. The image is recorded in JPEG format when the quality level is set to (Super fine (1)), (Super fine (2)), (Fine), or (Good). Images recorded in JPEG format are suitable for viewing on your PC or for attaching to e-mail.

ND (Neutral Density) Filter

A filter which reduces the amount of light entering the camera lens by a measured amount, without affecting the picture itself.

Noise Reduction

Process to reduce noise (image roughness or unevenness) caused by slow shutter speed.

NTSC/PAL

These are video output formats. NTSC is mainly used in Japan, North America, and South Korea. PAL is mainly used in Europe and in China.

RAW data

Unedited image data output from the CCD. RAW data is data before being internally processed by the camera. Settings like White balance, contrast, saturation and sharpness can be manipulated individually on each file. In addition, RAW data is 12-bit data that contains 16 times the information of 8-bit JPEG and TIFF data. Rich gradations are possible. Transfer RAW data to your computer and use the provided software to create image data with different settings, such as JPEG or TIFF.

sRGB (Standard RGB)

International standard of colour space established by the IEC (International Electrotechnical Commission). This is defined from colour space for PC monitors and is also used as the standard colour space for Exif.

Shutter Speed

The total exposure is proportional to the shutter speed. A fast shutter speed can capture a stopped motion of a moving subject.

Vignetting

Vignetting occurs when corners of pictures are darkened because the subject was blocked by the hood or filter or the flash was blocked.

White Balance

While shooting, colour temperature is adjusted to match the light source so that the subject appears to have the correct colour.
