Gradientxterminator: The Ultimate Gradient Removal Plugin for Photoshop



Gradientxterminator: A Powerful Photoshop Plugin for Removing Gradients




If you are into astrophotography, you know how frustrating it can be to deal with gradients in your images. Gradients are unwanted variations in brightness or color that can ruin the appearance of your photos. They can obscure faint details, reduce contrast, create artifacts, and make your images look unnatural.




Gradientxterminator Photoshop Plugin



Fortunately, there is a solution for this problem. It's called Gradientxterminator, and it's a gradient removal plugin for Photoshop that is fast and easy to use. It can process 32-bit, 16-bit, or 8-bit images, grayscale or RGB color. It can handle large-scale gradients from light pollution, vignetting, and calibration errors, as well as tricky edge, corner, and circular gradients that are hard to deal with otherwise.


In this article, we will explain what gradients are and why they are a problem for astrophotography. We will also introduce you to Gradientxterminator and show you how it works, how to get it, and how much it costs. By the end of this article, you will have a better understanding of how to improve your astrophotos with Gradientxterminator.


What are gradients and why are they a problem for astrophotography?




Gradients are variations in brightness or color across an image. They can be caused by various factors, such as light pollution, atmospheric conditions, optical defects, camera settings, or image processing errors. Gradients can affect any type of image, but they are especially noticeable and problematic in astrophotography.


Causes of gradients




Some of the common causes of gradients in astrophotography are:



  • Light pollution: This is the artificial light from cities, streetlights, cars, etc., that brightens the night sky and reduces its contrast. Light pollution can create a gradient that is brighter near the horizon and darker near the zenith (the point directly above your head).



  • Atmospheric conditions: This includes airglow (the natural emission of light by molecules in the upper atmosphere), aurora (the colorful display of light caused by charged particles from the sun interacting with the earth's magnetic field), moonlight (the reflected light from the moon), clouds (water droplets or ice crystals that scatter light), dust (tiny particles that reflect or absorb light), haze (a thin layer of dust or moisture that reduces visibility), etc. These factors can create gradients that vary in color and intensity depending on the location, time, season, weather, etc.



  • Optical defects: This includes vignetting (the darkening of the corners or edges of an image due to the lens or telescope aperture), coma (the distortion of stars near the edge of an image into comet-like shapes due to the lens or telescope optics), chromatic aberration (the splitting of light into different colors due to the lens or telescope dispersion), etc. These factors can create gradients that are darker or more colorful near the edges or corners of an image.



  • Camera settings: This includes exposure time (the duration of capturing light by the camera sensor), ISO speed (the sensitivity of the camera sensor to light), white balance (the adjustment of the color temperature of an image to match the ambient light), etc. These factors can create gradients that are brighter or darker depending on the camera settings.



  • Image processing errors: This includes flat-fielding (the correction of vignetting and dust spots by dividing the image by a flat image of uniform brightness), stacking (the combination of multiple images to reduce noise and increase signal), stretching (the enhancement of contrast and brightness by adjusting the histogram of an image), etc. These factors can create gradients that are artificial or exaggerated due to improper or excessive processing.



Effects of gradients




Some of the effects of gradients in astrophotography are:



  • Loss of detail: Gradients can obscure faint details, such as nebulae, galaxies, star clusters, etc., by making them less visible or blending them with the background. Gradients can also reduce the sharpness and clarity of details, such as star colors, shapes, sizes, etc., by making them less distinct or distorted.



  • Loss of contrast: Gradients can reduce the contrast between bright and dark areas, such as stars and sky, by making them more similar or uniform. Gradients can also reduce the dynamic range and color depth of an image, by making it more dull or washed out.



  • Creation of artifacts: Gradients can create artifacts, such as halos, rings, bands, stripes, etc., by introducing false or unwanted patterns or features in an image. Gradients can also create noise, such as speckles, grains, blotches, etc., by amplifying random variations in brightness or color.



  • Alteration of appearance: Gradients can alter the appearance of an image, such as its orientation, perspective, composition, etc., by shifting or tilting the brightness or color distribution. Gradients can also alter the mood and atmosphere of an image, by making it more warm or cool, bright or dark, calm or dramatic, etc.



Solutions for gradients




Some of the solutions for gradients in astrophotography are:



  • Prevention: This involves avoiding or minimizing the causes of gradients by choosing a dark and clear location, using a high-quality lens or telescope, adjusting the camera settings appropriately, etc.



  • Detection: This involves identifying and measuring the gradients in an image by using tools such as histograms, curves, levels, etc.



  • Removal: This involves eliminating or reducing the gradients in an image by using tools such as masks, filters, brushes, etc.



One of the most effective and popular tools for gradient removal is Gradientxterminator. Let's see what it is and how it works.


What is Gradientxterminator and how does it work?




Gradientxterminator is a Photoshop plugin that can remove gradients from astrophotos quickly and easily.
