TIFF Tag AntiAliasStrength

IFDImage
Code50738 (hex 0xC632)
NameAntiAliasStrength
LibTiff nameTIFFTAG_ANTIALIASSTRENGTH
TypeRATIONAL
Count1
Default1.0

Description

Used in Raw IFD of DNG files.

AntiAliasStrength provides a hint to the DNG reader about how strong the camera's anti-alias filter is. A value of 0.0 means no anti-alias filter (i.e., the camera is prone to aliasing artifacts with some subjects), while a value of 1.0 means a strong anti-alias filter (i.e., the camera almost never has aliasing artifacts).

Note that this tag overlaps in functionality with the BaselineSharpness tag. The primary difference is the AntiAliasStrength tag is used as a hint to the de-mosaic algorithm, while the BaselineSharpness tag is used as a hint to a sharpening algorithm applied later in the processing pipeline.
