Luminance, works HDR images from Ubuntu

About Luminance HDR

The images HDR (high dynamic range images) They came as a twist to the traditional concept of photography. The new camera models incorporate devices to capture several shots of the same subject with different exposures (the so-called "bracketing"). They can even process these photos and give you a high dynamic range image back to you without doing anything. I suppose there will also be a mobile that can do it, I don't know. The fact is that the HDR is there, so a simple way of working with these images also has to be present in Linux. That is why Luminance HDR was developed.

Luminance is such a veteran show that it even had time to change its name, before it was known as «Qtpfsgui». Luckily its creators had the healthy idea of ​​giving it a more humane name. I leave here your Official Site.

Luminance HDR 2.5.1 It is the latest stable version of the program. The latter is a bug fix version with some minor improvements over previous versions.

Some of the changes that this latest version brings us are the following:

  • The threshold for adjusting levels has been improved and made selectable.
  • Added feature interpolation optionally.
  • Full screen image browsing.
  • Now you can check the documentation online.

First we are going to add the corresponding repository to download it. We execute the command to add the PPA repository:

sudo add-apt-repository ppa:dhor/myway

As always, the system will ask us to write our administrator password.

Luminance HDR for Ubuntu

The application itself demonstrates simple operation. It seeks with reasonable success a difficult balance between the needs of advanced users and ease of use to get started with the program. The result is a program that, being quite complete and full of options, can sculpt HDR images in seconds with a couple of clicks.

Uninstall Luminance HDR

The PPA repository can be removed from System Settings -> Software and Updates -> Other Programs. We can also use the following command, which in turn will also remove the installed software and clean the residual packages:

sudo add-apt-repository -–remove ppa:dhor/myway  && sudo apt -–purge remove luminance-hdr && sudo apt autoremove

To finish, clarify that this program not Photoshop ni Gimp. We must also always keep in mind that in this matter of photography the important thing is the photograph itself and the way to take it, much more than the software with which we process the images. With Luminance you have to take care that our shots are well aligned, so it is convenient to take the pictures using a tripod.

In summary, Luminance is another program that should be part of our Linux arsenal if we are fond of taking pictures.

    Levels and threshold. Thank goodness, because it is essential for under or over-exposed images. We're going to try it. I hope it works in RAW format
