designated only for JPEG​

compressed data or​

uncompressed YCbCr​

data. The TIFF default is 1​

(centered); but when​

Y:Cb:Cr = 4:2:2 it is​

recommended in this​

standard that 2 (co-sited)​

be used to record data, in​

ordertoimprovetheimage​

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 does not have the​

capability of supporting​

both kinds of <YCb​

CrPositioning>, it shall​

follow the TIFF default​

regardless of the value in​

this field. It is preferable​

that readers be able to​

support both centered and​

co-sited positioning.​

Ascii​

Copyright 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.TheInteroperability​

copyright statement​

including date and rights​

should be written in this​

field;e.g.,"Copyright,John​

Smith, 19xx. All rights​

reserved.".Inthisstandard​

the field records both the​

photographer and editor​

copyrights, with each​

recordedinaseparatepart​

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​

thephotographercopyright​

is given, it is terminated by​

oneNULLcode.Whenonly​

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. Whenthe fieldis left​

blank, it is treated as​

unknown.​
