Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models. "to photoshop an image", " photoshopping", and " photoshop contest") although Adobe discourages such use. The software's name is often colloquially used as a verb (e.g.

Since then, the software has become the most used tool for professional digital art, especially in raster graphics editing. It was originally created in 1987 by Thomas and John Knoll.

For example, the RAW processing part is largely derived from Darktable (RAW decoding and color matrices) and RawTherapee (Amaze, LMMSE and IGV demosaicing algorithms).

After few email exchanges, it was clear to me that PhotoFlow was going to be built on top of VIPS.įrom there on, PhotoFlow has been entirely built on top of VIPS, re-using existing code whenever possible. Last but not least, the library is still in active development, and the authors are very responsive to user requests. No surprise that Wikipedia uses VIPS to scale-down large images ( ). VIPS is designed to process large images in a memory-efficient way, is intrinsically multi-threaded, and provides one of the fastest and better optimized processing frameworks on the Open Source market. Luckily, I came across a little software gem called VIPS, an image processing library originally written for processing multi-spectral images of ancient paintings. I'm not a professional programmer, and PhotoFlow is developed entirely in my limited spare time, therefore I could not afford one or more years for writing a decently optimized and fast processing engine.

allow the editing of rather large images (100 mega-pixels or more), without "killing" your machineĭeveloping a suitable processing pipeline has been my first big problem, and the main initial showstopper for the project.

allow local editing with grayscale blending masks.

support adjustment layers as well as layers grouping, to achieve complex effects.

provide a real-time preview of the current editing.

allow the direct processing of RAW files.

So I decided to take a different approach: define my ideal photo editor, see what building blocks could be used as a starting point, and eventually incorporate code from both Rawtherapee and Darktable whenever possible, just to avoid re-inventing the wheel.įirst of all, what could be the characteristics of an ideal photo editor? Here is my shopping list: No way for example to combine two or more exposures in a single image with extended dynamic range. Last but not least, they are both limited to single images. The current situation with Darktable is better, as it supports local editing through blending masks for most of the tools, however adjustment layers are not in the todo list of the developers. The conclusion was simple: it would imply rewriting a good portion of the processing pipeline. I remember having followed a discussion on the Rawtherapee forums about adding support for adjustment layers.

This is simply because none of the Open Source photo editors provides at the same time high-quality RAW development, adjustment layers and non-destructive local editing.

The typical workflow of a Linux photographer is to do the initial processing with a RAW developer like RawTherapee or Darktable, and then switch to GIMP for the final touch-ups.
