How to draw the tone of sketch

1. The five tones of sketch are generally drawn at the dividing line between light and shade. In painting, steps are generally drawn from darkness. If darkness begins, it must start from the boundary line of light and dark, which is a law. When drawing a boundary line, the position of the boundary line must be considered. If the position is set wrong, other colors will be painted in white. This question must be paid attention to.

2. excessive adjustment; There are two kinds of overshoot, one is dark overshoot and the other is bright overshoot. The difference between the two is that the bright part is bright and the dark part is heavy, so we should distinguish it well. But when drawing, we usually draw from the dark part, or from the boundary line to both sides at the same time. In overshoot painting, it is the most important part of sketch.

3. Bright color sketch has two parts; One is the part from highlight to overshoot, although it is in the bright part, but it also has a tone. It's just very light, but you must draw it, and you must draw it to the highlight.

4. Reflect light; There are two main considerations about reflective painting; First, when drawing a reflection, no matter whether there is a bright part in the reflection, the reflection cannot be brighter than the bright part. Second, whether there is a reflection, when considering the reflection in the dark, we must draw the reflection. Only when drawing a reflection, some are bright and some are not, so we should consider the reflection. Sometimes you have to draw them whether you reflect or not.

5. About the drawing method of projection; When drawing a projection, we should consider the rationality of the perspective relationship of the projection. If there is a problem with perspective, it will affect the effect of the whole picture.

Several skills of grasping proportion in sketch;

1. aspect ratio: When you want to draw the position of an object, make a horizontal line running through the whole picture and see all the objects on this line.

2. Vertical ratio: Make a vertical line running through the picture and pay attention to all objects on this line.

3. Look at the real thing more and look at the picture less: In order to form the consciousness of observation, abandon the original concepts in the brain. Look at the object for 5 seconds, and look at the picture for 2 seconds. The eyes should repeatedly observe and compare between the picture and the object.

Generally speaking, it is to take a long-term view, look at the whole and compare more. It will be easier to think of these as warp and weft; Beginners should draw more auxiliary lines, and when they have a deep foundation, you will find that you will draw fewer and fewer auxiliary lines and imagine more and more auxiliary lines in your mind.
