Using Lab Mode in Photoshop to Process Spring Scenery Photos

The spring breeze is caressing the shy white clouds with a pleasant smile. She will dance and glide across the sky with her charming body. She will thaw frozen rivers. She will awaken the green buds on the branches. Dear friends, the time for outing is coming. Is your camera ready? What colors are you going to use to record the spring scenery of 2008?

Don’t worry when you find that the colors in your photos don’t express the overflowing beauty of spring. The Lab mode in Photoshop is the colorful brush in your hand. Let us wave the "paint brush" together to add a bit of vitality to the spring scenery.

Tips:

Lab mode in Photoshop is a color mode that does not rely on external devices. It consists of brightness (L) channel, a channel and b channel. Among them, the brightness ranges from 0 to 100; a represents from green to red, b represents from blue to yellow, and the color values ​​​​of a and b both range from -120 to 120. These three channels include all color information.

Lab mode also supports multiple layers, with three monochromatic channels L, a, and b and color channels mixed by them.

In theory, Lab mode can create all colors. Its color range covers all colors in RGB mode and CMYK mode. When RGB mode and CMYK mode are converted to Lab mode, their color information will not be lost. Therefore, when converting RGB mode and CMYK mode to each other, they actually need to be converted to Lab mode first.
