Members

Member nameDescription
APERTURE_VALUEThe lens aperture value.
ARTISTThis tag records the name of the camera owner, photographer or image creator. The detailed format is not specified, but it is recommended that the information be written as in the example below for ease of Interoperability. When the field is left blank, it is treated as unknown. Ex.) “Camera owner, John Smith; Photographer, Michael Brown; Image creator, Ken James”
BITS_PER_SAMPLEThe number of bits per image component. In this standard each component of the image is 8 bits, so the value for this tag is 8.
BODY_SERIAL_NUMBERContains camera body serial number
BRIGHTNESS_VALUEThe brightness value.
CAMERA_OWNER_NAMEContains camera owner name
CFA_PATTERNIndicates the color filter array (CFA) geometric pattern of the image sensor when a one-chip color area sensor is used. It does not apply to all sensing methods.

COMPONENTS_CONFIGURATIONThe components configuration.
COMPRESSED_BITS_PER_PIXELSpecific to compressed data; states the compressed bits per pixel.
COMPRESSIONThe compression scheme used for the image data. When a primary image is JPEG compressed, this designation is not necessary and is omitted.
CONTRASTThis tag indicates the direction of contrast processing applied by the camera when the image was shot.
COPYRIGHTCopyright information. In this standard the tag is used to
indicate both the photographer and editor copyrights. It is
the copyright notice of the person or organization claiming
rights to the image. The Interoperability copyright
statement including date and rights should be written in this
field; e.g., “Copyright, John Smith, 19xx. All rights
reserved.”. In this standard the field records both the
photographer and editor copyrights, with each recorded in a
separate part of the statement. When there is a clear distinction
between the photographer and editor copyrights, these are to be
written in the order of photographer followed by editor copyright,
separated by NULL (in this case since the statement also ends with
a NULL, there are two NULL codes). When only the photographer
copyright is given, it is terminated by one NULL code . When only
the editor copyright is given, the photographer copyright part
consists of one space followed by a terminating NULL code, then
the editor copyright is given. When the field is left blank, it is
treated as unknown.

recommended in this standard that 2 (co-sited) be used to
record data, in order to improve the image quality when viewed
on TV systems. When this field does not exist, the reader shall
assume the TIFF default. In the case of Y:Cb:Cr = 4:2:0, the
TIFF default (centered) is recommended. If the reader

be able to support both centered and co-sited positioning.
