What is the principle of light. I will not confuse you with scientific explanation, and we'll keep it in the simple applicable form. If you like to make a form looking three dimensional, you have to correctly capture the light on the forum. We do capture the light through shading. To understand how to shade, you have to understand how light affects the form and the form itself. There are two main characteristics, light and shadow.
In the shadows zone, there are two types of shadow. Form shadow is the part of the object hidden from the light and the shadow is the shadow that the object drops onto another one objects. What happens in the form shadow as you see in the part of the form shadow there graded tones of darkness. The first and most intense is the core shadow. The image where the form transitions from light to shadow is the Terminator. It appears exactly on the edge of this transition and has the same form as the object.
You can clearly see it's an oval, another straight line. Because of the form of the ball. The core shadow is only visible because of the reflection. reflection is the place where a light reflects and has lessons sensitive to both. If there is no reflected light, there will be no core shadow, like the moon on the sky. In the natural core shadow is the most intense and therefore has the darkest value, form shadow Islam sentence in comparisons to the core shadow and the reflection is less intense of the both.
When we throw them, we need to manage at least three values in three different graded tones. In the cap shadow with the most intensity is the occlusion shadow. The position of it is always the closest to the object and fades away. Moving on to the light zone. Immediately after the Terminator is the halftone. The halftone is getting lighter and lighter because it gets closer and closer to the center light.
The center light is the plane facing the light source. And the place reflecting the light source is the highlight. It has the most intensity of the light. Let's create them again. The health term is intense the center Light is more intense, and the highlight is the most intense. Again, we need to manage three values in three different graded tones.
The highlight depends on the surface of the object. If the surface of the object is for example, peach, it's not reflectable and therefore, there will be no highlight. But the Polish tech will greatly reflect the light and therefore highlight will be visible, it is allowed to saturate them to better describe the forum. Let's put this theory in practice now. I will work with to be in for the pencil in the shadow zone and ah in the light zone and draw the object in a classical way. The strokes are light, embracing gradually the plane without any outlines.
I draw lines with the same length, intensity and without gaps in between. Let's be now First I will make the shadow sound in the same value of darkness. I use the sight of the pencil for more thicker outlines. For this reason, I've sharpened the pencil not with the sharper, but with an art knife. This allows me to use the longer lead. My stroke is most touching the paper only from right to the left.
I don't go left right right left. I do gradually darken. I don't make it once the layer of darkness, but building layers I open layers gradually till I have even the value of darkness in the whole plane of the shadow zone. This will be my first layer, the layer of reflection the lighter one Now I'm going with the second fellow of darkness above, building the form shadow. I will net out the place of the reflection and the rest. I'm going to darken again layers Ivan layers gradually and smoothly.
In the beginning, you will need more practice for holding the pencil in that way and controlling the pressure of the hand. But keep in mind it's only practice and nothing but practice. I have already two tones for the reflection in the form shadow. Now I'm going to draw the core shadow with the utmost intensity. The core shadow will give me the three dimensional appearance of the object. If you like to have a good result, you have to make the transitions very smooth.
That means, for example, the course shadow dissolves into form shadow in the shadow zone and into halftone. In the light zone, no outlines only find transitions. The fine transitions give the additional values of the tones and you will manage to have more than three. The more you have, the more realistic your object will look like. Now I will make the occlusion shadow fade away gradually in the cast shadow. Again, layers upon layers.
Now I'm going to get into the shadow sound of the object to integrate all the three characteristics together. I will darken them a little bit more. In the light zone, I will work with each pencil, beginning with a halftone. It should become lighter reaching the center light again, in the same manner, layer seven layers I can make the center light in this way through erasing and shading above It could be finished as it is now, but let's make the highlight It's gonna look like this. Let me finish it in a way I like it's like this. The basic principle is you keep gradually darkman don't put it once the darkest layer rather than building it.
Layer I've been there gradually. This principle is not valid for drawing but for painting to and later on when you work with colors, you do only translate the intensity of the values in colors. And believe me, you cannot lose yourself in the colors anymore. This basic is evitable if you'd like to create a three dimensional form in graphics or Fine Art
