When drawing still life sketches, not the entire object has to be wiped with a paper towel. Generally, the dark side of the object, the projection, and the light and dark junction are wiped.
Wiping with a paper towel will blur the lines, and the relationship between black and white and gray will achieve a virtual effect, so that the still life becomes three-dimensional.
Draw the chiaroscuro line in the structure and clarify the big tone. Wipe quickly when you lay them out, and use the corners of paper to wipe the details carefully.
Of course, when rubbing, you can't use too much force, the relationship between the interlining, the object, and the wall should be pulled apart, and the relationship between black, white and gray should be clear. Dark should be dark, bright should be bright, so that the sense of hierarchy will be more intense.
First draw the structural relationship to distinguish the three major faces, wipe the dark surface with a pen and paper before lining the line.
Pay attention to its shape when painting cabbage, it is like a cylinder. Perspective should be well grasped and shaped according to the modeling method of the cylinder. The leaves must be whole, not broken, dark color can be wiped with a paper towel, and then the line, cabbage leaves should be integrated into the whole.
In addition to the reasonable composition of the still life sketch, the relationship between black, white and gray of the picture should be clear. The jar is the heaviest, the lining is the brightest, the tabletop and background are grayer, and the relationship between the vegetables should be black and white.
When drawing a jar, beginners can first express the structure, mark the light and dark junctions, and then use a paper towel to wipe the effect along the junction.
The surface of the metal object is smooth and reflectively strong, and the response ratio is strong when shaping, which clearly defines the highlight area. Dark should be dark, bright should be bright, and the brush used to paint is tough and meticulous.
