Description
Mask data Adobe Camera Raw and Lightroom save beside a photo (starts ACR). It shares the .acr extension with the DICOM image format, and no converter here reads it yet.
Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
