• Non-destructive editing throughout the complete workflow, your original images are never modified.
• Take advantage of the real power of raw: All darktable core functions operate on 4x32-bit floating point pixel buffers, enabling SSE instructions for speedups.
• GPU accelerated image processing: many image opertions are lightning fast thanks to OpenCL support (runtime detection and enabling).
• Professional color management: darktable is fully color managed, supporting automatic display profile detection on most systems, including built-in ICC profile support for sRGB, Adobe RGB, XYZ and linear RGB color spaces.
• Cross platform: darktable runs on Linux, Mac OS X / macports, BSD, Windows and Solaris 11 / GNOME.
• Filtering and sorting: search your image collections by tags, image rating (stars), color labels and many more, use flexible database queries on all metadata of your images.
• Image formats: darktable can import a variety of standard, raw and high dynamic range image formats (e.g. JPEG, CR2, NEF, HDR, PFM, RAF … ).
• Zero-latency, zoomable user interface: through multi-level software caches darktable provides a fluid experience.
• Tethered shooting: support for instrumentation of your camera with live view for some camera brands.

IrfanView seeks to create unique, new and interesting features, unlike some other graphic viewers, whose whole "creativity" is based on feature cloning, stealing of ideas and whole dialogs from ACDSee and/or IrfanView! (for example: XnView has been stealing/cloning features and whole dialogs from IrfanView, for 10+ years).

IrfanView was the first Windows graphic viewer worldwide with Multiple (animated) GIF support. One of the first graphic viewers worldwide with Multipage TIF support. The first graphic viewer worldwide with Multiple ICO support.
