1. After preparing the drawing tools, determine the height and width of the jar on the sketch paper. You can use the center line or other auxiliary lines to get the shape right. Use tangents to create the basic outline of the can. Note that the top of the jar is smaller than the bottom. Then draw the location of the projection.
2. After making the basic shape of the jar, analyze the direction of the light and find its light and dark boundary. Pay attention to the changes in the level of the boundary between light and dark. Note that there is some reflection under the jar, so it should not be painted too dark. The same goes for projection, pay attention to the reality in the front and the virtual in the back.
3. After drawing the light and dark boundary line of the jar, you can first lay a layer of color on the dark side and the projection. Pay attention to the connection with the light and dark boundary line, and the changes in color levels must be transparent. The dark part of the bottle mouth should be shaped carefully to make it look stronger. After drawing the dark part, you can also wipe it with toilet paper to make it look smoother and more uniform
4. After drawing the dark part of the jar, use a medium carbon pen to draw its gray surface, paying attention to the transition between the light and dark lines, and also There must be contrast. Then use a hard charcoal pen to draw the glossy side of the jar, and finally draw the highlights. Shape the mouth of the jar and leave highlights to make the mouth of the jar appear stronger.
Notes:
Pay attention to the correct shape
Pay attention to the main tone of light and dark
Pay attention to the relationship between black, white and gray
