First of all, let me say hello to everybody in this forum: this is my first post, although I've been frequently visiting the luminous lanscape in the past years, always learning something new each time.
I would like to introduce to the readers of this forum a new open source RAW editor, called PhotoFlow, hoping that there will be people interested in the project.
PhotoFlow is a fully non-destructive layer-based editor, which means that the image processing is performed using layers and
layer masks (like in photoshop). It can directly read and process RAW files, using code inherited from
Darktable and
RawTherapee.
The list of provided tools is already quite complete:
- loading of
RAW, TIFF and JPeg files, including EXIF data and embedded ICC profiles
- fully color-managed processing in floating-point precision
- real-time preview of the processed result
- on-the-fly colorspace conversions
- several color-correction tools:
- brightness/contrast adjustment
- custom tone
curves - channel inversion
- horizontal, vertical and radial gradient
- hue/saturation adjustment
-
black & white conversion (desaturation or channel mixer)
- gaussian blurring
- sharpening
-
cropping, scaling and rotating
- optical corrections via lensfun (experimental)
- interface with the
G'MIC filters:
- several smoothing algortihms, including the well-known "
dream smoothing"
- color and B&W
film emulation - tone mapping
- interactive
foreground extraction-
freehand drawingAll tools are implemented as non-destructive layers (except a couple of very slow ones), meaning that the tool parameters can be tweaked at any moment and the effect immediately seen in the preview window. The layers structure, including masks and tool parameters, can be saved as a sidecar XML file.
I am providing an up-to-date windows installer
here, and Ubuntu packages are available from Dariusz Duma
PPA. Linux users can also compile the code from source following the instructions given
here.
Here are few additional resources: github
repository, project's
homepage,
google+ page and dedicated
blog with several step-by-step tutorials.
The project is relatively young (about 1 year of spare-time development) and the program is likely to crash from time to time, however I think that it has already reached a stage where complex edits can be created, saved and exported to TIFF or JPeg. Moreover, given the editing approach similar to photoshop, lots of tutorials and well-known techniques can be successfully used in photoflow with (hopefully) not too many difficulties.
I will greatly appreciate any positive or negative feedback, with the hope to get professional and advanced users involved in the project, especially for reporting their experience and suggestions for improvement. Please take into account that I'm by no means earning my life with this project, I'm just working on it for fun, intellectual interest and personal research.
Thanks for looking!
