Software

I prefer to use and support free software. Currently all my workflow consists of software licensed under GPL or similar. I pay no licence fees but I donate to help projects of my choice.

Linux Mint
User friendly distribution of GNU/Linux operating system based on Ubuntu. Complete and easy to use replacement of Windows or Mac OS X. Most of the software I use is available from Mint/Ubuntu software repositories. All you need to do is to find it in the list and click Install button. Your application of choice will be downloaded and installed without any user intervention needed. GNU/Linux systems offer better performance and better security compared to proprietary systems.

Darktable
Photography workflow application and high quality raw developer. Full replacement of Lighroom. Another excellent raw converter you should check out is RawTherapee.

Gimp
A mature alternative to Photoshop. It is under active development; check out the product road map. There is a wealth of plugins and filters available too, like Wavelet Decompose or Exposure Blend to simulate HDR and tone-mapping in one step.

Hugin
Powerful panorama photo stitcher. Whether you need to stitch a couple of hand-held shots or a full spherical panorama, Hugin will offer you all the tools and knobs to get the job done. Recently supporting also HDR. The sheer number of buttons and levers might seem little overwhelming for a novice user but well worth the learning. There is also a simple wizard tool available to automate most of the process.

Piwigo
Full featured on-line photo gallery (for techies: PHP + MySQL application). Available are templates and wide range of plugins and configuration options.

Pannellum
A light-weight panorama viewer built using HTML5, CSS3, JavaScript, and WebGL. You can view my spherical panoramas here.

Kdenlive
A mature non-linear video editor I use for both my video projects and new slideshows from still photographs.

Diascope
A slideshow generator for Linux command line. It creates high quality photo shows with music, that I upload to Vimeo and Youtube. I get music licensed under Creative Commons from Jamendo.

GAP
GAP is an animation plugin for image editor Gimp. I have used it to create visual trace of an off track tramping trip on a topographic map. You can see the result at the end of this video slideshow.

Stellarium
Great tool for astro-photography. Do you want to know what was that bright object in your night sky shot the other day? No problem, just dial in your GPS coordinates, date, time, and rotate the sky in the direction of your shot. Then read the labels off your screen.

Colour Management

My current colour management is limited to my LCD monitor only. To create the ICC colour profile I use ColorMunki Display colourimeter (monitor calibration gadget) and Argyll colour management software with DisplayCAL GUI frontend. Once the ICC profile is set in the operating system, many aplications can use it to display accurate colours:

Note: To get mpv to use default system profile, add following line into configuration file ~/.config/mpv/mpv.conf:

vo=opengl-hq:icc-profile-auto

If you wonder about difference between display calibration and profiling, make sure you read this article.

If you want to create an image with perceptually uniform steps like the one below, read this step-by-step tutorial. And if you cannot see all 21 steps of the image, consider calibrating and profiling your screen.

Other Resources

Documentation of lighting setup
A handy template for creating diagrams that show positions of your subject, camera, lights and modifiers, together with notes and comments. Great for sharing the setups with other photographers. Download the file from here. Open it in Gimp and save as .xcf format for future use. Similar template is also available here, including on-line version.
