5/10/2023 0 Comments Lightzone java runtimeThe new release of LightZone adds another distinctive tool called ToneMapper, which is a generalization of the contrast mask technique available in many raster image editors. It is a very intuitive way to adjust a photo the visual feedback is instantaneous and the control chart interface is far superior to incrementing and decrementing a text-box of decimal values. As with all tools in LightZone, you can add multiple ZoneMappers to your image in any order. You can grab any point on the chart and slide it up or down to adjust the image’s brightness, you can add multiple control points to make finer adjustments, and you can add but not move control points to keep certain brightness levels fixed. A ZoneMapper is a flexible control that plots the luminance of an image against an Adams-style zone system chart.Īs you mouse over the chart, LightZone highlights the matching-brightness portions of the image in its preview box. LightZone mimics the zone system with its ZoneMapper tool. The methods involve consciously re-mapping the brightness of a scene (from shadows to highlights) so that all 10 zones are covered this is what gives Adams’ photos their wide tonal range without making them look artificially contrasty. The zones are the 10 steps from absolute black to absolute white that are discernible to the human eye. The original zone system is a set of methods for measuring the dynamic range in a real-world scene and reproducing it in print by adjusting exposure and development. LightZone takes its name from the zone system popularized by photographer and writer Ansel Adams. It is easier to get the image you want by making separate adjustments to distinct problem areas than by trying to find one setting that corrects everything. In a lot of ways, that is a more natural approach to touching up photos: the actions that you take are the primitives, rather than the esoteric mathematical qualities of the conversion. With this approach, you can mask off different portions of the image for each adjustment, or you may find it easier to think about the necessary color correction in two steps. Change your mind about the first one? Just click the X button and ditch it the rest of the adjustments are retained. ![]() Then you can adjust the color to your liking, and if you wish, add a second color balance action on top of it. In contrast, LightZone treats each adjustment you make as a separate entity - somewhat like an adjustment layer in Adobe Photoshop lingo.įor example, to adjust the color balance, you click on the color balance tool, and it is stacked on top of your previous adjustments. Most RAW converters give you one control for each possible image feature - white balance, exposure compensation, and so on. All adjustments are reversible, and nothing touches the original file. You can stack as many of them onto the image as you want, rearrange them, disable them, even remove them. Instead, it gives you a sparse toolbar of adjustment functions. If you have used a RAW photo app before (such as Bibble or Raw Therapee, for instance), then you probably expect to see a glut of slider controls filling up every spare inch of vertical screen real estate, broken up by a few check boxes and spin buttons. (The company used to provide both bundled-runtime and standalone versions of the app, but found that the standalone versions were causing more problems than they solved.) When the download is complete, you can untar the file to any location on your system and launch it with. The current Linux bundle (version 2.1) weighs in at a hefty 25MB, thanks to the included Java runtime. LightZone is written in Java and was designed from day one to be cross-platform, so when Kast started work on it, he did so on his platform of choice, all the while making sure that the Linux builds worked just as well as those for proprietary operating systems. ![]() Kast is the company’s chief architect, was the first employee, and is a die-hard Fedora Linux user. The LightZone Web site focuses on the commercial products to get the Linux build you must visit a separate page maintained by Light Crafts’ Anton Kast. It is a lucky break, too, because LightZone is a powerful tool that bests many of its expensive competitors on both quality and ease of use. But although the Windows and OS X versions of LightZone cost hundreds of dollars, the Linux version is absolutely free. Like many companies, Light Crafts releases its flagship application - the RAW photo converter LightZone - for Windows, Mac OS X, and Linux.
