Hi, everyone. My name is Mario. I'd like to welcome you to this lesson on value.
So I'll explain what value is, jump into different types, and then see why it's important in visual design. And as always, feel free to stop, fast forward, and rewind at your own pace. And when you are ready, then let's begin.
So value is another term for lightness or darkness. And value uses a grayscale between white and black to develop form integrity. And what I mean by that is that using a combination of light, which is the elimination aspects to form, dark, which is the absence of light and provides way to form, and gradient together, which is the range between light and dark, as it pertains to value, yield developed form with all these things.
So for example, if you take a black rectangle and incorporate that combination of dark and light values, you can turn it into a cylindrical form. And likewise, you can turn this boring circle into a sphere. The subtle use of gradation to create dramatic value is called chiaroscuro, which is Italian, I believe, for "light dark." And it's used in many great paintings, but it's not limited to it.
So you can see from these next examples the great use of those creating dark and light values to create drama and form. And I really like this one. It's really beautiful. And it's not as realistic as this last one we just saw, but it has great use of value. And it's quite lovely. It's wonderful.
And like I said chiaroscuro is not limited to just paintings. It can also be applied to photos. And it doesn't necessarily have to be super dark or gloomy, like some of the other ones. As you can see here in this very beautiful Italian landscape.
So it actually covers our quick lesson for today. We'll conclude with our key terms, which were value, light, dark, gradient, and chiaroscuro. I hope you've enjoyed today's lesson on value. My name is Mario. And I will see you next lesson.
