DRIFTT

DNG-Enabled RAW Image Format to TIFF Converter

DRIFTT interface

What is DRIFTT?

DRIFTT is a batch-converter for converting RAW camera image files into TIFF format and Adobe's open standard RAW format - DNG. It allows you to preview TIFF output of individual files and adjust brightness, rotation, set white balance, assign colour spaces and more. It also creates MD5 checksums to provide an archival file storage option.

DRIFTT TIFF conversion is based on dcraw - an open source RAW library by David Coffin ( http://cybercom.net/~dcoffin/dcraw). For simplicity not all dcraw features were made available in DRIFTT.

dcraw is well known for its excellent quality conversions. It is being used in many free and commercial applications.

For conversion to DNG, Adobe's free DNG Converter is employed in its command-line capacity. To extract technical metadata, excellect free ExifTool by Phil Harvey is being used from command-line.
