How to quickly remove the white and purple edges in the photo?

This is a problem that many photographers will encounter. The various edges in a photo are really annoying and can destroy a good photo. Today we will learn how to remove the edges quickly and effectively.

01. The removal of white edges is a kind of miscellaneous edges that often appear in the later image revision, which is often white and appears on the edge of the object. Especially with matting or partition adjustment, there will be a layer of white edges at the boundary, such as the image below.

Let's open ps and create a new blank layer. Next, select the Clone Stamp tool, sample to "all layers" or "current and below layers", change the blending mode to "darken", or use layer mode instead.

Then sample in the sky where the white edge is tight, and then use a small brush with a hardness of 0 to smear along the white edge, the white edge will be removed, and will not affect other pixels.

02, the removal of other light edges such as light edges appear during shooting, there are cyan edges, red edges, purple edges, etc., high-quality lenses are less likely to appear light edges, so the price of high-end lenses is also very expensive. Red edge and green edge are often caused by the quality of the lens, while purple edge is often caused by high light than backlight shooting in the environment, which belongs to the dispersion of the lens, especially the strong light and telephoto.

The first removal method is in the "Lens Correction" panel of the ACR filter, which has a "de-edge" function, and we can choose the color of the light edge to remove, as well as the intensity of the removal.

However, this method has a drawback, that is, it will remove the edge for the overall situation, which is easy to be accidentally hurt and not flexible enough. For example, if you choose to remove the red edge, the objects that are already red in the photo will also be affected, and even red complementary colors will appear.

The second method is to choose the ACR adjustment brush, other parameters are set to zero, only "go to the edge" to set an appropriate parameter, and then use the brush with small hardness and size, smear along the place where you want to go.
