When we travel, we are always attracted by the beautiful scenery and hope to capture the scenery forever through our cameras. However, due to shooting technology and equipment, some photos with light spots are often taken in places with strong sunlight. Sometimes it can be a rather idiosyncratic picture effect, but most of the time it's annoying. Here we will introduce to you how to use Photoshop to eliminate those annoying light spots in photos.
A photo in Figure 1, the theme is terraced fields. Because the shooting position is facing the sun, a large glare is produced around the sun on the left side of the picture, leaving green spots in the middle and lower right side. Seriously affects the quality of the picture. But it doesn’t matter, we will use Photoshop to fix it right away, so follow along.
1. Clever use of Photoshop’s LAB color mode
LAB color mode may be unfamiliar to you. It is a color mode with the largest color gamut in PS and can be used to adjust the color of pictures. An important difference between it and other color modes is that the LAB color channel stores the brightness channel and the A and B channels. The brightness channel only records the light and dark information of the picture, and the color is recorded by the A and B channels. Today we will use this feature to eliminate the light spots in the picture.
Step 1: Keep the image in RGB color mode, and then observe the three channels of red, green, and blue of the image. We will find that the intensity and amount of light spots in the three channels are different. Among them, the red channel and blue channel have fewer light spots (Figure 2), while the green channel has the most obvious light spots.
We choose a channel with fewer light spots to copy. Here we choose the red channel with more reasonable light and dark. After copying, the red copy channel is generated (Figure 3).
Step 2: We convert the image to LAB color mode. Check LAB color in the mode submenu of the image command menu. At this time, our picture will change from RGB color mode to LAB color mode. After the transformation we open the channel control panel. Now there is a brightness channel and two channels A and B (Figure 4).
Step 3: We keep the red copy channel selected, then press CTRL+A to select all, and press CTRL+C to copy the red copy channel. After copying, we select the brightness channel of the picture, and then press CTRL+V to paste the red copy channel into the brightness channel. At this time, we find that the brightness of the photo becomes darker, and at the same time, part of the light spots disappear (Figure 5).
