How to install LightZone on Ubuntu 20.04 – A Image Editor for Linux

LightZone is a free, open-source digital photo editor application. It’s an light weight application that requires less storage than most software in the category Design & photography software. With its stylish and well designed layout, the application provides easy access to numerous image browsing and editing tools.

Users will be able to access numerous image adjustment tools, for altering the color balance, sharpening, saturation, blur, etc. as well as predefined filters: black and white, high key, infrared, soft and many more. LightZone edits both JPEG and RAW format images. This application can create and apply pre-determined image transformations called “styles” to an entire batch of images in a single operation.

The RAW format is supported and It’s an non-destructive RAW editor, but unfortunately the editing capabilities for it are very restrictive and might not appeal to more experienced users. This application could be a good choice for those who are just getting into image processing techniques and prefer a more basic approach.

LightZone outputs JPEG files which contains a record of the transformations applied during editing and metadata references to the original image file location. It’s an cross-platform application available for Microsoft Windows, Linux and macOS.

Key Features of LightZone

Step #1

First of all open the terminal from system application launcher and type the following command to add the LightZone PPA to your system.

$ sudo add-apt-repository ppa:lightzone-team/lightzone

Step #2

Then, execute the following commands to install LightZone package on your Ubuntu system.

How to Uninstall LightZone from Ubuntu 20.04

For some reason, If you want to uninstall LightZone, refer one of the below procedures.

Procedure #1

It’s most likely that you added the PPA using add-apt-repository command. You can use the same command to remove the PPA as well. Just give it --remove option in the command.

$ sudo add-apt-repository --remove ppa:lightzone-team/lightzone

Note: Use this procedure only if you need to remove the PPA and not the applications installed by it.

Procedure #2

You must have noticed that in the above procedure we only talked about deleting or removing a PPA. What about the applications installed using these PPAs? Will they be removed as a result of removing the PPA? The answer is NO.

So this is when ppa-purge comes in picture. It not only disables the PPA but also uninstalls all the programs installed by the PPA or revert them to original version provided by your distribution.

So type the following command to install the ppa-purge package and uninstall the LightZone package.

$ sudo apt install ppa-purge && sudo ppa-purge ppa:lightzone-team/lightzone
