Those who have studied sketching taught me how to use pencils 2B, 4B, 8B and HB. What are their functions and how to use them?

Oh, oh, okay, let's start with hb. I seldom use this. I had a bad impression when sketching in my early years, because my modeling ability was limited at that time, so I kept revising it. Hb's lead core is hard, and the sketch soft glue is not clean, so there is too much paper drawn with 4b glue, so even if it is molded, 2b pencil is used. However, it was later found that the plaster sketch needed to be arranged at last, and hb was still good. Of course, it is important to adjust the strength of the hand.

2b Pencils are in good shape. Of course, for me, it's just a plaster cast. If it is scenery or something, I will still choose a pencil above 4b. Of course, it doesn't matter which one you choose now, but you will still care when you reach a certain learning stage.

4b pencil is good for dividing line between light and shade, and many shades can be drawn by adjusting hand strength.

8b pencils are rarely used, of course, but they are rarely used later, because they look deep, but the lead will reflect light. Sketch painting pays attention to the overall relationship between light and shade, not the darker the color, the reasonable relationship between light and shade is the last word. So it is rarely used.

The above is just my personal experience of drawing with a pencil, and the landlord will understand it after trying it slowly.
