How to apply a graduated filter to the digital photo

Are you fond of traveling? If so, you must often take landscape photos. When shooting a landscape, you may come across this common situation. You set an appropriate exposure for the foreground but the sky ends up being overexposed. Generally speaking, to avoid this happening, you can place a graduated neutral density filter in front of the camera to reduce the light on the upper parts of the lens. Thus, the sky will be darkened and more details will be brought out in the clouds. Sometimes you forget to take the graduated ND filter with you on the photography outing. Then, how do you process the photo that is shot without such a filter? The answer is using the graduated filter tool in photo editors. This tool simulates a real graduated density filter and creates a graduated filter effect. Although there are a lot of photo editing programs with graduated filters on the market, most of them have steep learning curves. If you are a photo editing beginner and looking for an easy-to-use photo editing software to handle the task, please continue reading this article. In this article, I will introduce to you a beginner-friendly photo effect editor and show you how to use it to apply a graduated filter to a photo.
