How to add a graduated filter effect to a photo

If you are a type of person who likes photography, you certainly often go out for tours and shoot landscapes. When you take photos of beautiful scenery, you may encounter such an issue. The exposure for the foreground is set properly but the sky in your photo winds up being somewhat blown out. To prevent this from happening, you can put a graduated neutral filter before the camera to reduce the light on the upper part of the lens. This will balance the light levels between the sky and ground, ensuring all areas in the photo will be well exposed. Sometimes, you don't have a graduated neutral density filter at hand. Then, how to deal with the photo that is taken without the grad ND filter? As a matter of fact, you can take advantage of photo editors to apply a simulated graduated filter effect to your photo to darken the sky. There are plenty of photo editing programs that come packed with graduated filter tools. But many of them are not suitable for photo editing beginners. If you are looking for beginner-friendly software to help you get the job done, please continue reading this post. In this post, I'll introduce an easy-to-use app to you and show you how to add a graduated filter effect to a photo with it.

A series of parameters are located in the right-side panel. You can modify the contrast, saturation, and brightness. What's more, you can compress the dynamic range and tone-map the HDR photo. In addition, you are allowed to modify the local contrast, adjust the sharpness of the photo, mix the color channels, and reduce the noise level in your photo. Other parameters are vignette filter, Lab adjustment, vibrance, graduated filter, and soft light.
