SCNR, or Subtractive Chromatic Nose Reduction, is a process that intelligently removes color noise of a specific color. At its default settings, it removes the green cast in your astronomical images. SCNR can be...
Using MultiscaleLinearTransform To Sharpen An Image
MultiscaleLinearTransform, or MLT, is typically used for noise reduction but you can also use it for sharpening an image based on wavelet layers. You can get an idea of what structures are at specific wavelet layers...
Using ColorSaturation
The ColorSaturation process, under Process – IntensityTransformation, is used on nonlinear images when you want to modify the color saturation based on hue. ColorSaturation preserves color balance allowing you to make adjustments freely. Using...
Using The ColorMask Script To Create A Mask Based On Color
The ColorMask script creates a mask using the color information in your image. Using the color information in your image can be useful late in your processing workflow when you want to, for example,...
Using LocalHistogramEqualization To Improve Contrast In An Image
LocalHistogramEqualization can improve the contrast of low contrast regions of a nonlinear image. Use LocalHistogramEqualization late in the workflow when your image is nonlinear. The process offers a real-time preview so you can get...
Using HDRMultiscaleTransform To Increase Contrast
HDRMultiscaleTransform is a great tool for increasing contrast in areas of high signal. It’s an easy to use tool, but it relies on having a suitable mask in place to protect areas you don’t...
Using TGVDenoise To Reduce Noise In An Image
TGVDenoise is a noise reduction process in PixInsight that you can use both with both linear and nonlinear images. When open TGVDenoise, the process looks like this: The default is the RGB/K mode, which...
Boosting Areas of Faint Signal Using Curves, StarNet and Other Processes
Sometimes your image includes some areas of faint signal like the nebula in the following image (Sh2-240): In this case, the nebula has a relatively low signal. If you begin your workflow by integrating...
Using BackgroundNeutralization To Neutralize The Background Of An Image
BackgroundNeutralization makes an adjustment to the entire image to make the background more neutral. Use BackgroundNeutralization when your image is in its linear state and after using a process like DynamicbackgroundExtraction to address gradients...
Using ColorCalibration To Calibrate An Image
The ColorCalibration process automatically calibrates the colors in your image based on a sample of white pixels and background pixels. You can provide the sample of white pixels or can allow ColorCalibration to acquire...
