![]() ![]() The second is used to control the saturation (mode Filmic, Perceptive, or Colorful) as well as for fine control of the contrasts. RawTherapee's dual tone curves also exist in ART: the first is often used to adjust luminance via the Luminance, Weighted Standard, or Saturation and Overlay modes. This is important because the saturation subjectively increases as the brightness decreases. The third section, Tone Curves, now contains a dedicated saturation control in addition to the two tone curves. On the left is the original image on the right, the tonal map has been activated. However, if you look at what the ART developer, Alberto Griggio, is doing, the reason for choosing RawTherapee as a foundation quickly becomes apparent: The developer is rebuilding or extending the existing tools ( Figure 1).Ĭorrect effects caused by the lens-camera combinationįigure 5: The tonal map shows the tonal range to which individual image sections or their pixels belong. With that in mind, it may be surprising at first that RawTherapee is the basis for a fork, ART. Similarly, darktable has offered masks for years, but RawTherapee has not. For example, RawTherapee has nothing like a cloning or stamping tool, which even the far older LightZone has. To date, it includes a number of excellent exposure tools, but it still may not have all the features you're looking for. A third option that appeals to many users is LightZone, a Java application that was formerly proprietary but is now open source.ĭarktable offers new releases at short, regular intervals that often extend or completely replace its current collection of 60 or more tools, but RawTherapee's development is proceeding at a slower pace. RawTherapee is a bit smaller, but scores points with users for its "good-natured" behavior and ease of handling. Darktable is the most comprehensive and complex of these programs. Three major RAW converters are available for Linux so far. This article takes a look at the current state of this project and how it's progressing toward those goals. This young project combines some tools and concepts found in two well-established programs, RawTherapee and darktable, and attempts to offer additional functions, while also providing a user friendly, streamlined program. Rawzor compressed images can be decompressed to get back the image file in its original format.ART, which stands for Another RawTherapee, is a RAW converter for photo editing. cr2 file is preserved within the compressed. For example, birthday.cr2 will after compression become The naming convention also indicates that the original. FPV Codecs add support for showing preview and meta-data of Rawzor compressed images in Windows explorer.FastPictureViewer supports Rawzor compressed images since March 2010.Manuel Llorens' fast precompiled dcraw binaries include Rawzor support.Zoner Photo Studio supports Rawzor's compressed images starting with version 12.ExifTool added Rawzor support in September 2008.Raw Therapee added Rawzor support starting version 2.4 on both Windows and Linux.XnView provides plugin to support Rawzor compressed images.Konvertor supports natively Rawzor compressed images.Some of the software supporting Rawzor compressed. SDK is available for 32-bit and 64-bit Windows, Mac OS X and Linux. Rawzor has released a free SDK using which many image processing software provide support to open and edit Rawzor compressed images. Decompression gives back exactly the same original file. It is completely lossless, there is absolutely no loss in image quality or meta-information.This is significantly better than compression obtained by zip or rar on image files. Typically provides between 20% and 60% space savings depending upon the raw format. ![]() Complete list of supported formats and cameras is on the website. It is available for Microsoft Windows and Mac OS X. Rawzor is a proprietary lossless image compression software which compresses camera raw images without any loss in image quality or meta-information. ![]()
