Switchover (part 3): Polarr

Third part in this switchover series, today I want to talk about Polarr.

Polarr is a multiplatform web-based photo editor, loaded with features and with a very pleasant interface. It is technically a web-app, but done so well that you barely notice it. Actually, I had to read it online, otherwise I would have never discover that.

Polarr on launch. It has a very clean interface (yes, I switched to standard Ubuntu and GNOME).

Polarr comes in two interfaces, User and Pro, the latter offering more options. I started straight away with the Pro interface having some experience with photo editing.

There are several options for editing, masking, exporting, cropping, rotation…. the only thing it does not do is coffee.

The controls are superb, despite being unable to manually input numbers. These sliders show the effect that sliding in one or the other direction will have and they offer live preview, so you can see the effect as you slide (something that darktable still hasn’t and annoys me). The histogram is shown on the upper left corner, but it is possible to move it around the screen as preferred.


Curves are included and are very neatly implemented in a non intrusive way. It is possible to work on the general curve or on the single colour components.

There are several adjustments available, which can be applied globally (on the entire picture) or locally (through the use of masking). Masking can be elliptical, gradient or set manually with a brush tool.

There is a huge selection of filters available.

There are also filters, available, although they are more like “presets”. Once applied, their settings can be completely altered and it is also possible to save your own presets/filters. Very handy as starting points or for quick fixes.

Exporting options. Not a vast selection, but functional.

All edits can be undoed and restored, they are saved separately from the picture itself. It is possible to save a copy of the edited pictures via the Export function which shows the window above. It is possible to set custom metadata, apply a custom watermark, single and batch exporting. Batch exporting also allows for batch renaming and filter application.

Polarr is free to use, and can be downloaded from the official website (or used straight from there, as a matter of fact). There is also a subscription  (less than £30/year) that offers some more features and works with all versions. It is available for Windows, Linux/ChromeOS and macOS. I highly recommend this software!


Switchover: ditching Windows 10 for the Penguin – an overview (part 1)

This article is part of a series about what software I use to manage pictures in my new GNU/Linux setup. Further posts will get into individual pieces of software in more detail. The first bit is introductory and explains my history with GNU/Linux. You may want to skip ahead, if you don’t want to read me being nostalgic…

I have grown up with “bread and computer” – aka, I’m quite tech-savy.  I started my computing journey 18 years ago with Windows 98 SE and tried all major operating systems since then. From 2003, I always had a Linux distro installed on my main PC at home together with Windows (I switched versions of Windows many many times, mainly in 2001 I jumped several times from 98 to XP and back). I also had a MacBook from 2007 until 2014, when it died in the summer.

My experience with Linux started in 2003, I found a three CD edition of MandrakeLinux 9.2 “FiveStar” with a magazine. I tried and fell in love with it. It took a while to understand how the shell worked, but the operating system installation and administration was done completely via GUI. Struggled a lot to make my USB DSL modem work, so I was without web access on the Linux partition. At a certain point, I divided my 15GB hard drive in three, Windows 98, Windows XP and MandrakeLinux.

I also discovered just today, by chance, that Mdk 9.2 had a bug in which some LG CD-ROM drives had their firmware erased by mistake – my LG drive died on my first installation of Linux, but I though it was just random… today I found out it was not!

With Mandrake I started to learn about the kernel, the shell, how X11 works, KDE (3.1) and GNOME (2.4), LILO, the partitioning scheme and so on and so forth. And everything without a working DSL connection.

I was initially a KDE enthusiast, so all the distros I used I preferred to work with KDE 3. After jumping left and right, I settled with Kubuntu and then Ubuntu when they started to ship KDE 4 (never got used to it). I have been using GNOME/MATE and Cinnamon since.

The distro I currently have installed is Linux Mint 18.3 “Sylvia”, a distro based on Ubuntu Xenial LTS, which adds a few bits and bobs, some customised tools, a perfectly integrated desktop and Cinnamon, a desktop environment which is based on GNOME 3 but maintains a more traditional metaphor with a taskbar and a menu. Being based on top of Ubuntu, it is possible to use loads of Ubuntu packages, Ubuntu repositories and PPAs. And, of course, it is completely free of charge.

I decided to ditch Windows, forget about the antivirus issues, Office, subscriptions and so on and so forth and just keep Linux as my main OS. The time is definitely mature now.

The main issue with switching to Linux today, is software. There is loads of great software for Linux and a lot of popular packages that work on Windows are compiled also for Linux. Some others, unfortunately, are not. On Windows this is what I used almost daily:

  • MS Office
  • Adobe Photoshop and Lightroom
  • Google Chrome
  • Mailbird
  • Spotify
  • Steam (sometimes I need to play and distract myself, you know)

Steam, Spotify and Chrome exist also for Linux and are distributed from their official websites, so no problem there. They all work perfectly fine. Mailbird exists only for Windows, but on Linux I tend to use GNOME Evolution (more similar to Outlook but less bulky). A more similar alternative would be Geary Mail. Microsoft does not compile a version of Office for Linux, so an alternative is needed and that alternative is LibreOffice.
Also Adobe does not play well with Linux (it used to develop Flash Player and Adobe Reader for Linux, but that is no longer the case), so Photoshop and Lightroom require alternatives. I have installed a couple of packages to try and see what works best for me, but for the moment my software of choice is (of course) the GIMP and Darktable.

By the way, all these Linux packages I mentioned are also available for Windows, if you want to give them a try. They are part of the so called “Open Source” software. These programs have their source code public so everyone can modify them and redistribute them freely. Linux itself is an Open Source operating system (for most parts, but that gets really complicated) – despite everyone having access to its core components code, it is a very stable, solid and secure system.

In the next posts of this series, I will test different software and see how they behave and how they work for me and decide for which I want to keep and use for my daily tasks.
