0xc71c​50972​Image​ RawImageDigest​

Undefined​This tag is an MD5 digest​

of the raw image data. All​

pixels in the image are​

processed in row-scan​

order. Each pixel is zero​

padded to 16 or 32 bits​

deep (16-bit for data less​

than or equal to 16 bits​

deep, 32-bit otherwise).​

The data for each pixel is​

processed in little-endian​

Long​

Normally, the pixels within​

a tile are stored in simple​

row-scan order. This tag​

specifies that the pixels​

within a tile should be​

grouped first into​

rectangular blocks of the​

specified size. These​

blocks are stored in​

row-scan order. Within​

each block, the pixels are​

stored in row-scan order.​

The use of a non-default​

value for this tag requires​

setting the DNGBackward​

0xc726​50982​Image​ ProfileLookTableData​

Float​

This tag contains a default​

"look" table that can be​

applied while processing​

the image as a starting​

point for user adjustment.​

This table uses the same​

format as the tables stored​

in the ProfileHueSat​

MapData1 and Profile​

HueSatMapData2 tags,​

and is applied in the same​

color space. However, it​

should be applied later in​

the processing pipe, after​

any exposure​

compensation and/or fill​

lightstages,butbeforeany​

tone curve stage. Each​

entry of the table contains​

three 32-bit IEEE​

floating-point values. The​

first entry is hue shift in​

degrees, the second entry​

isasaturation scale factor,​

and the third entry is a​

value scale factor. The​

table entries are stored in​

the tag in nested loop​

order, with the value​

divisions in the outer loop,​

the hue divisions in the​

middle loop, and the​

saturation divisions in the​

inner loop. All zero input​

saturation entries are​

required to have a value​

scale factor of 1.0.​

Double​NoiseProfile describes the​

amount of noise in a raw​

image.Specifically,thistag​

models the amount of​

signal-dependent photon​

(shot) noise and​

signal-independentsensor​

readout noise, two​

common sources of noise​

in raw images. The model​

assumes that the noise is​

white and spatially​

independent,ignoringfixed​

pattern effects and other​

sourcesofnoise(e.g.,pixel​

response non-uniformity,​

spatially-dependent​

thermal effects, etc.).​
