Subtitles of the Movie (Adobe Photoshop CS4 for Photographers / Adjustments / Vibrance & Saturation)
Adobe added the Vibrance and Saturation Adjustment dialog to Photoshop CS4 Vibrance was originally added to just Camera Raw and earlier versions of Photoshop but it proved to be so popular and useful that they added it to Photoshop as well, and although there is an entire sophisticated dialog devoted just to saturation they included a Global Saturation Slider as well. The Saturation Slider affects all the colors equally and increases or decreases the saturation throughout the image. You can go from completely desaturated, which becomes a monotone image, to grossly oversaturated where you tend to lose detail in some of the different oversaturated areas. The Vibrance Slider is very similar, if not identical, to the one in Camera Raw. It selectively increases or decreases saturation, affecting less saturated colors more than more saturated colors in an attempt to decrease or avoid clipping and lost detail in saturated areas. So as I pull this, even if I pull it all the way to its extreme, you see that we maintain detail in the umbrella here and throughout the image. Similarly, when I decrease the Vibrance all the way, you see that some of the reds and yellows, and some of the very saturated blues are less effected. They're still there, they haven't become totally monochromatic as they did with the Saturation Slider. In addition the Vibrance Slider affects skin tones less than other colors so that some yellows and reds are less effected than blues and greens. I can increase the Vibrance Slider and still have very reasonable looking skin tones while I boost the saturation in the sky and other areas. Similarly I can decrease it and still have some color left in the skin tones. If I tried that with Saturation, as I boost the Saturation the skin tones become very unreal looking and as you've seen before, if I pull the Saturation Slider all the way to the left the image loses all of it's color. There are times when you'll want to use a combination of both of these Sliders. Keep in mind that you can usually be more aggressive with the Vibrance Slider than with the Saturation Slider. And generally speaking, a light hand is better than too heavy a hand when dealing with Saturation. Most of the time you don't want a garish image. In addition, areas that are oversaturated will lose detail because you're forcing the colors to their most saturated state, and the more pixels that become the same color with less variation the less detail you'll have. I don't recommend that you use the Saturation Slider to turn an image into black and white by desaturating it all the way. There are far better ways to do that such as with the Black and White Adjustment that we'll cover in another movie.
