![]() The methods of boosting color discussed below are most applicable to deep-sky imaging of nebulae and galaxies, but can also be applied to all forms of digital photography. How to Boost the Colors in Your Astrophotography ImagesĪstrophotography is a broad term and covers a wide variety of disciplines from wide-angle Milky Way nightscapes, to high-magnification planetary imaging. If you need help with the pre-processing stages of deep-sky astrophotography, be sure to check out my premium image processing guide.įor an overview of this process, please watch my video tutorial on YouTube: The data used in this tutorial was registered, stacked, and calibrated in DeepSkyStacker first. ![]() The color boosting methods I describe will work for all color images, whether they are broadband RGB, LRGB, narrowband, bi-color, etc. The example images in this article were captured using a variety of cameras, from an astro-modified DSLR camera to a monochrome CCD camera. I have also found it to be a fantastic start-to-finish image editor, with the help of a few third-party plugins of course. (See the rest of the astronomy and astrophotography software I use). This software includes countless tools to perform the finishing touches on your images. ![]() In this tutorial, I’ll use Adobe Photoshop to accomplish our tasks. By exaggerating these colors through post-processing, we can increase the impact of the image. Long exposure astrophotography can reveal the colors of all deep-sky objects and galaxies. The Triangulum Galaxy in RGB (Dedicated Astronomy Camera). The definition of a “true-color” image varies, but the techniques described in this tutorial are generally accepted in the astrophotography realm. ![]() I’d like to consider my images to be somewhere in the middle. Some prefer bright, vibrant colors, while others prefer a toned-down “natural” look. The amount of “boosting” is up to you of course. Increasing the saturation of your deep-sky object can bring out the true beauty of your subject, and better showcase the contrasting elements of the nebula or galaxy. I like to call the technique “ selective color boosting“. In this astrophotography image processing tutorial, I will explain an easy way to selectively boost the colors in your image. ![]()
