A blog on photography, food, travel and things that take my fancy. Wednesday, 17 March LightZone - A beginners tutorial, well sort of This is an edited version of the article I mentioned in this post. LightZone does true non-destructive editing, the image is not altered and all edits are transformations applied to the original, resulting in a new image.

I only encountered errors when installing Java piecemeal; specifically, I hit a java. Installing LightZone LightZone can be downloaded from lightzoneproject. On Linux, you can install LightZone in two different ways. You can either install it to your filesystem using checkinstall or you can just run it from your user directory. LightZone basics LightZone, like Darktable and a few closed source competitors, is designed to be a photography workflow application. An ideal user is anyone who takes lots of photos—such as a wedding photographer, a studio photographer, or any average tourist with a cell phone—and needs to ingest hundreds or thousands of shots, sort through 5 or 10 versions of essentially the same subject, choose the best one of the bunch, touch up any imperfections, and publish the results.
When you first launch LightZone, it starts in Browse mode. At first, your workspace is empty, so you can choose a folder containing images from the file tree on the left. The moment you select a directory with images in it, the images are loaded into the LightZone browser: thumbnails on the bottom third of the window, large preview on top. Using the browser toolbar, you can adjust thumbnail size, rotate images, sort by file name, file size, or even metadata, such as your own rating, capture time, focal length, or aperture setting.
Right-clicking on any thumbnail reveals even more actions, including the ability to rename, convert, and print the image. A single-click on any thumbnail makes it the active selection. A control-click on two images brings both images up in the viewer, side by side, for easy comparison. You can view several images in your browser at a time up to five on my display; after that, you may as well adjust the size of the thumbnails and view the photos that way.
Each preview image that appears in the top panel has an Edit button overlaid in the bottom right corner. To edit an image, click Edit on the photo, or click the Edit button in the upper left corner of the LightZone window to bring the active selection into the edit view. Edit In the edit what you might think of as the "digital darkroom" view, the main areas of interest are: The left and right side panels hold presets and filter palettes.
The center panel displays your image. If you feel you need more room to work, hide panels using the vertical tabs on the left and right of the LightZone window. Your workflow will probably start with the panel on the right.
Underneath the Zones panel, there is a horizontal list of available filters. Any filter placed on a photograph appears in the filter stack underneath the filter list. Filters The filters in LightZone are, to me, a perfect mix of simple but must-have effects similar to those found in digiKam and Darktable, plus a few surprisingly powerful tools rivaling functions found in the likes of GIMP. For the former group, LightZone offers a zone mapper—like a levels filter, but from a more Ansel Adams perspective—hue and saturation control, sharpen and blur, white balance, color balance, and noise reduction.
Something that sets LightZone apart is that each of those "standard" filters also has a selection- and color-based constraint system, so any filter you apply can be done on only part of your image. Other applications can do that, but the fact that LightZone builds the option in on every default is a real time-saving convenience.
LightZone filters Another little surprise that LightZone ships with is the clone filter. By default, the clone filter clones an image and overlays it onto itself. Presets Each filter can have a preset—a temporary snapshot of a setting that you want to keep on hand, which is sort of a reverse-undo function.
Then, imagine that you adjust the filter again but end up with something less appealing that you had before. Styles More complex than filters, and far more permanent, are Style. Whereas a preset lasts for only as long until you overwrite it with a more recent snapshot, a style gets saved to your LightZone configuration forever. Preset styles are available in the left side panel. If the preset style options are not visible, click the Styles vertical tab to reveal it.
Hovering over a style displays your photo in the upper left corner, with that filter applied. Double-click the style name to apply the filters it contains to your photograph. LightZone Styles Any combination of filters can be saved as a Style with the Add a new Style button at the top of the window. By default, this gathers all current filters and settings from your currently active image and wraps them in a style.
Compare the contrast To "flip back" to your original image as you edit, click and hold the Orig button in the top toolbar.
Release to get back to your edit in progress. History The history palette on the left is an undo stack that persists while you work. When you leave Edit mode, your history goes away. History Saving images To save an image, click the Done button in the top toolbar. This option never overwrites your original photo; it saves a new version, differentiated by inserting lvn in the filename. The format that LightZone saves to is determined by your LightZone preferences. There are three tabs in the Preferences window: General: Set how much RAM LightZone can use, the location of its scratch folder, the color profile of your display, and more.
Save: Default file format of saved exported images and associated options compression levels, bit depth, ppi, and so on. Copyright: The copyright and copyleft message to embed into exported images. Being Java-based, LightZone is easy to install on all platform, ensuring a consistent workflow across all users. And the results speak for themselves. Try LightZone out and let me know what you think of it. He has worked in the film and computing industry, often at the same time.
