305 JPEG An image compression method. In this camera, select from C (Best), D (Better), or E (Good). Images recorded in JPEG format are suited for viewing on your computer or for attaching to e-mail. ND (Neutral Density) Filter A filter available in different saturation levels that adjusts the brightness without affecting the color tone of pictures. Noise Reduction Process to reduce noise (image roughness or unevenness) caused by slow shutter speed or high sensitivity shooting. 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. Quality Level This refers to the image compression ratio. The lower the compression, the more detailed the image. The image becomes rougher as the compression rate rises. RAW data Unedited image data output from the CMOS sensor. RAW data are data before being internally processed by the camera. Camera settings at the time of capture, such as White Balance, Contrast, Saturation, and Sharpness can be set for each frame after shooting. In addition, RAW data are 12 bit data that contain 16 times the information of 8 bit JPEG 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. Recorded Pixels 11 Indicates the size of the image by the number of pixels. The more pixels that compose a picture, the larger the image size. Appendix Shutter Speed The length of time that the shutter is open and light strikes the CMOS sensor. The amount of light that strikes the CMOS sensor can be changed by altering the shutter speed.
