Iridient C-Transformer

Version 2.0.1

Convert Canon RAW images to DNG format.

Iridient C-Transformer overview

Iridient C-Transformer is a utility that can be used to convert Canon RAW images to DNG format using Iridient Digital's high-quality RAW processing algorithms. Much of the core RAW processing, sharpening, noise reduction and lens corrections featured in this program are shared with Iridient Developer a more full-featured RAW processor that is available only for macOS.

The Iridient RAW processing routines have been in active development for over 12 years for use in Iridient Developer and have been optimized and refined over the years for the best possible image quality. Iridient Developer is widely regarded as one of the highest quality RAW processors available.

The key RAW processing stages that can be applied by Iridient C-Transformer during conversion to DNG include:

  • Interpolation or demosaic processing. This transforms the camera sensor's Bayer color filter information to produce a full-color RGB image. This processing is always applied by Iridient C-Transformer and cannot be disabled or undone. There are two interpolation options, one for a more detailed rendering and a second smoother, lower artifact version. The algorithms are identical to the latest "detail+" and "smooth" options in Iridient Developer 3.3.9.
  • Sharpening. Iridient C-Transformer features advanced sharpening based on the very highly regarded "Iridient Reveal" sharpening algorithms featured in Iridient Developer. Sharpening is optional and can be adjusted (low/med/high) or disabled.
  • Automatic lens corrections for distortion, chromatic aberration, and vignetting. Corrections are based on native Canon lens information specified in their RAW metadata. The lens correction stage is optional and lens correction information can also be passed on through DNG opcode metadata and left to later processing stages or ignored altogether. The lens correction processing in Iridient C-Transformer uses the same high-quality resampling algorithms as Iridient Developer.
  • Color and luminance noise reduction. The noise reduction processing in Iridient C-Transformer shares much in common with the latest noise reduction available in Iridient Developer and is specifically optimized for RAW image processing. Noise reduction is optional and can be adjusted (low/med/high) or disabled.

What’s new in version 2.0.1

Updated on Jan 11 2022

New features:
  • Support added for RAW images from the Canon EOS R3.
  • Support added for RAW images from the Canon EOS M50 Mark II (EOS Kiss M2).
  • New image processing pipeline. Now optimized for both Intel and Apple silicon (M1/Pro/Max) processors.
  • The macOS application is now native for both Apple silicon (M1/Pro/Max) and Intel processors. Application launch is now faster and most operations are 30-50% faster on Apple silicon Macs.
  • The macOS application is now optimized for macOS 12 Monterey.
  • Improved luminance noise reduction algorithm.
  • Improved color noise reduction algorithm.
  • Wider adjustment range for sharpening and noise reduction options.
  • New clarity adjustment added.
  • Support for sharpening masking to more selectively sharpen edge/detail areas.
  • New option to automatically taper sharpening strength off as image ISO increases.
  • Settings presets can now be saved to and loaded from files.
  • Adobe Lightroom plug-in now supports a preferences dialog with file prefix/suffix customization and sub-folder options.
  • Improved RAW processing.
  • Adobe Lightroom plug-in should be more reliable at finding RAW master images.
  • Updated camera calibration and DNG color profile information for models newly supported in Adobe's latest DNG Converter 14.1 update.
