Canon Digital Photo Professional vs Nitro

Canon Digital Photo Professional is free Windows and macOS software for viewing, processing, editing, and printing RAW images from compatible Canon EOS digital cameras and RAW-capable PowerShot models. It imports and edits Canon CR3 RAW, HEIF, and JPEG files, with output in JPEG, TIFF, or HEIF. Editing controls include rotation, white balance, dynamic range, colour, and tone-curve adjustments. Diffraction Correction and Digital Lens Optimizer provide lens corrections. Recipes offer preset-based editing shortcuts, while star ratings, bulk renaming, and bulk resizing support photo organization and output. Neural network processing covers digital lens optimization, noise reduction, and demosaicing. Compositing and Depth Compositing functions are listed for reducing noise and sharpening details. Colour management supports sRGB, Adobe RGB, Wide Gamut RGB, and ICC profiles. Canon also lists EOS Utility for remote camera control and transfer, plus Picture Style Editor for creating styles used in DPP.
