How to get rid of headlamp light pollution in your aurora photos.
If you have been on a venture to photograph the northern lights, then you have encountered the challenge of photographing in the dark while still being able to control your camera settings. A headlamp with a red filter can help provide the necessary light to assist with camera adjustments. However, that light can easily find its way into the picture if you are not careful. In order to avoid headlamp light pollution in your aurora photos, see headlamp etiquette practices on my blog article here.
If you end up with a photo that includes some unwanted headlamp light, don’t throw it away just yet. You may be able to remove that headlamp light pollution without too much trouble in Lightroom. I prefer Lightroom because it offers an environment where all alterations to an image are made on the RAW file itself.
Here is an example of one such image. Someone (not to be named) on recent photo tour did not have their headlamp pointed in the down position, which resulted in red light being broadcast upon the snowy foreground. Here are some screenshots for a quick fix of this.
First, reduce the saturation and luminance of the portion of the image which contains the unwanted red color. Select “Saturation” and click the little radio button icon on the left, then hover over the red portion of the photo and click and drag downward with your mouse and watch the desaturation process until you are satisfied. Then select “Luminance” and repeat this process.
