This simple guide shows how to install latest LightZone 4.0 on Ubuntu 13.04 Raring, 12.10 Quantal, 12.04 Precise, and Linux Mint from its official repository.

LightZone 4.0 from official repository

LightZone is professional-level digital darkroom software for Windows, Mac OS X, and Linux. Rather than using layers as many other photo editors do, LightZone lets the user build up a stack of tools which can be rearranged, turned off and on, and removed from the stack. It’s a non-destructive editor, where any of the tools can be re-adjusted or modified later — even in a different editing session. A tool stack can be copied to a batch of photos at one time. LightZone operates in a 16-bit linear color space with the wide gamut of ProPhoto RGB.

LightZone 4 Main Window

Features:

  • edit both RAW and JPEG format images.
  • has ability to create and apply pre-determined image transformations, called “styles”, to an entire batch of images in a single operation.
  • It’s a non-destructive RAW editor. It treats the digital image original (typically a RAW file) as precious and non-editable.
  • outputs JPEG files which contain metadata references to the original image file location and a record of the transformations applied during editing.
  • Because the JPEG output files contains the entire transformation history, edits can always be undone in a new edit session, long after they were saved

The developer of Xfce Theme Manager wrote this simple tool, and it has the ability to control below settings:

  • Shadow opacity.
  • Shadow delta X, Y, width and height.
  • move window opacity.
  • inactive window opacity.
  • frame opacity.
  • resize window opacity.
  • popup opacity.

Also it provides options to swich on / off composite, dock shadow, frame shadow, pop-up shadow and Restart VM to apply changes.

Below is what the developer said in GTK-Apps, “These settings are available via the xconf settings editor but that is one of the most awkward GUI’s I have ever used as you have to select the xfwm4 channel, expand the tree, scroll to the option you want, select it, click edit, change the setting and click save, then the tree gets collapsed and you have to start again! So this nice simple GUI to control the composite manager, the settings are self explanatory.”

CherryTree is a hierarchical note taking application, featuring rich text and syntax highlighting, storing data in a single xml or sqlite file.

CherryTree is perfectly suitable not only for taking notes, but also for managing code snippets. The application supports syntax highlighting for many popular programming languages, so you can use the application as a programmer’s scratchpad. You can also insert code snippets directly into notes using so-called code boxes.
