A couple of days ago, after 6 years of development, the release of GIMP 2.10 was announced.

- G'mic Plugin Install For Mac Os X Versions
The latest version of GIMP (v 2.8) now runs native on Mac OS X, and is also available for Windows, and Linux users. Our goal is to maintain an open source workflow for openFITS, and as such, we will utilize GIMP in our tutorials. The main concepts covered are easily transferrable to other image editing software. Jun 14, 2017 Install G’MIC plugin for GIMP image editor in Ubuntu Linux. G’MIC is a full featured GIMP Plugin for image processing. The latest release, G’MIC 2.0 comes with a new versatile interface, based on Qt. It also brings smart coloring, an original automatic line-art coloring filter.

- Jan 29, 2019 Testing the plugin. To test the plugin, simply open the GIMP and try the plugin. If this plugin makes a certain image type supported, try opening a file of that type. If the plugin is a filter, test it. If the plugin appears to not be working, be sure that its for your OS.
Well, our builds are not far behind this time. Introducing GIMP 2.10 with the usual bells and whistles you have come to expect from this build.
The raw image editor Nufraw is included as usual.
See above!
With this build as before, you can use all the brushes you'll ever need.
G'MIC has been updated to latest pull as well. For the Mac OSX build, G'MIC requires an additional X11 interface which has been provided in this version. Please let me know if you face any issues.
If you have been using Photoshop, then you must be familiar with using the camera-raw plugin on any current image/layer you wish to. Well, with this build, you can consider doing the same by using LightZone as the 'camera-raw' plugin. Of course, you have to make sure that you have installed it in its default location. Special thanks to Stefano Azzi for providing this plugin.
One needs to be a little vigilant while using LightZone. Please be sure to save and close the application or your edits will not be transferred back to GIMP.
Finally if you want to provide just a hint of HDR to your image or go all grunge, you can always open the Nik Collections HDR Pro to get the job done.
Needless to say, you have to have the Nik Collection installed in its default location. openFITS - Create Images from Raw Data

Introduction and Background - Images and Color
The colors we see are the result of how the human eye and brain perceive different wavelengths of light in the visible part of the electromagnetic spectrum - roughly radiation in the range of 380 nm to 740 nm. The ability of the human eye to distinguish colors is based on the varying sensitivity of different cells in the retina to light of different wavelengths.
A false-color image is an image that depicts a subject in colors that differ from those a faithful full-color photograph would show. The term false-color is typically used to describe images whose colors represent measured intensities outside the visible portion of the electromagnetic spectrum (ie. invisible to the human eye). Color astronomical images are usually false-colored, though the term false-color is misleading here. Coloring an astronomical image involves the careful selection of colors chosen to represent some characteristic in an image, such as intensity, energy or chemical composition. 'True Color' images translate intensity information from the invisible to the visible by assigning colors to individual images and combining them. The colors chosen, usually Red, Green and Blue are usually mapped according to wavelength such that the longest wavelengths of light present in the image are mapped to Red, while shorter wavelengths move through Green and Blue. The colors selected are representative of the physical processes underlying the objects in the images, and display in a single image, as much information as possible that's available from the data; think of it as 'representative color'. Raw, grayscale image data are transported into image analysis software where adjustments are made to emphasize the individual features or processes that scientists are interested in - or enhanced for aesthetic purposes. It is important to note that at no point in this process are the images modified to create something that isn't already present in the data. Astronomical image processors maintain a careful balance of art and science enhancing the image while meticulously preserving the integrity of the data. See x-ray 101 for more information on how Chandra 'sees' x-ray light.
Flexible Image Transport System (FITS) Image File Format
FITS is a digital file format used mainly by astronomers to store, transmit, and manipulate scientific data and images. The FITS format was designed specifically with scientific data in mind and includes a rich, human readable, ASCII metadata header capable of providing very detailed information about the contents of a particular file. These details include very specific information regarding the nature and source of the data, the time when the data were created, as well as photometric and spatial calibration information. In the openFITS project, you will use raw or minimally processed FITS data from the Chandra X-ray Observatory to create your own color images! The FITS Index will be a repository for all of the FITs files used in the project. A Word on Software and Open Source
Image Scaling: A Quick Lesson In Bit Depth
Any image that you view on your computer screen has a bit depth associated with it. Bit depth refers to the number of colors that can be displayed in any one pixel in your image. The higher the bit depth, the more colors used in the image, and consequently, the larger the file size. In an 8-bit gray-scale image, for example, each pixel within the image can appear as one of 256 different shades of gray. The number 256 comes from the fact that bit depth increases as powers of 2, 28 = 256. A 16-bit image, therefore contains 216 or 65,536 potential color values for each pixel. Most astronomical images come in the form 16-bit images, and with over 65,000 color values per pixel, there is more information, or dynamic range in an image than can be displayed on the screen, or even viewed by human eyes. Image scaling is used to project the dynamic range of an image into a range that is suitable for display on a monitor. A scale function manipulates the pixel values before projecting them to the screen. The example on the left shows a linear scaling of the supernova remant E0102 on top of the same image scaled logarithmically.The ability to properly scale your data before working with it is crucial to creating dramatic and interesting images.

the GREYCstoration smoothing plugin will show up in Filters->Enhance->GREYCstorationG'mic Plugin Install For Mac Os X 10 13 Download
. As of GIMP v2.8 with the latest version of G'MIC v 1.5.2.4, GREYCstoration is considered obsolete and has been incorporated into the suite of G'MIC image manipulation tools. To find the equivalent of GREYCstoration within G'MIC, load an image and click through to Filters->G'MIC... Within the G'MIC dialog, navigate to Enhancement->Smooth [anisotropic] and you'll be greeted with an interface similar to the GREYCstoration interface for contour preserved image smoothing.Disclaimer:The Chandra X-ray Center and the Harvard-Smithsonian Center for Astrophysics do not endorse any particular vendor's products.
