Lossless rotation
Because JPEG uses irreversible compression (data are lost during compression), the quality of JPEG images deteriorates when uncompressed, rotated and then saved. Lossless rotation, however, can be used to rotate JPEG images without recompressing the data. Exif and other data are maintained. Images for which lossless rotation is performed are processed as separate files; the rotated image appears after the image file is saved.
PNG format
Images saved using this format can be compressed to a small file size, but the reversible compression of this format makes the file size larger than JPEG. This format is for use with
RAW data
Unedited image data output from the image 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 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.
Spurious Color Signal
Occurring in the vicinity of clearly defined lines or fine patterns, this signal results in the appearance of colors that are not a part of the original subject or scene. This phenomenon occurs because each individual pixel on
sRGB (standard RGB)
An international color space standard defined by IEC (International Electrotechnical Commission). This is defined from color space for computer monitors and is also used as the standard color space for Exif.
