Vibrance and saturation perform pretty similar (though different) functions, and it can be difficult to tell the differences between them at times, but there are certain situations in which one will give you better results than the other. This excellent video tutorial will show you the difference between the two and how to use each of them to get better colors in your images.
Coming to you from Mike Smith, this great video tutorial will show you the difference between vibrance and saturation. A lot of the time, vibrance and saturation can produce pretty similar results, but the basic way they operate is different and has an appreciable impact in many scenarios. Saturation works to increase the intensity of all colors in an image at the same time, no matter how intense they were to start with. On the other hand, vibrance increases hues that are less saturated more than those that are already more intense while also trying to avoid saturating skin tones too much or maxing out any individual color channels and creating posterization. In a way, vibrance is like an advanced version of saturation. Remember, both are still global adjustments that work on all colors, so if you want to get more precise, you’ll either have to turn to masking or the HSL panel. Check out the video above for the full rundown from Smith.
