Hello Linux Geeksters. As you may know, PhotoFlow is an open-source, non-destructive photo editing software for adjusting photos from RAW images to high-quality printing.

Main features:
- Fully non-destructive, layer-based photo editing workflow with realtime preview of the final image
- Support for 8-bits and 16-bits integer as well as 32-bits and 64-bits floating point precision, selectable at runtime and on a per-image basis
- Plugin-based architecture: new tools can be implemented as separate modules that are loaded at runtime
- Allows to load and edit images of arbitrary size, thanks to the underlying rendering engine based on the VIPS library
- Fully color managed workflow: user-defined input, work and output profiles, soft-proofing, etc…
- Support for layer grouping and layer masks
- Support for common photo editing tools: levels, curves, brightness-contrast control, blurring, sharpening, cropping, resizing, colorspace conversions, etc…, all implemented in the form of image layers
- User-friendly interface to develop new tools and image filters as external plugins
