5 value system

 





1. light tone
2. half tone (in shadow)
3. form shadow (=core shadow)
4. reflected light
5. cast shadow






Cast shadows: Shadows made when the light is blocked from hitting an adjacent surface
Form shadows: Shadows made by the turning of the form, away from the light source.


The form shadow is the shadow that is on the form itself, created as the form turns or faces away from the light source. Form shadows have soft, blended edges; however, on cubes and angular objects, the form shadows have hard edges.
The second type of shadow is the cast shadow. The cast shadow is created when an object blocks the light and ccasts a shadow onto adjacent surfaces. cast shadows are darker where closer to the object, and they slightly lighten in value as they move away from the object. Cast-shadow edges are crisp, and they slightly soften as the shadow moves farther away from the object.

    Thank you for your the introduction. Now I know what is the meaning of the 5 value. I was study drawing and painting. But when I study drawing used my first language, which is Chinese. So I didn't know how use English express the different highlight and shadows. The 5 value is very important for express an object's 3 dimension, and I think I need more practice the 5 value in drawing.

    Yeah I knew something was wrong with your last blog because every time I tried to post a comment I could not, I stayed up until 12a.m trying to post a comment on the blog. Thanks for fixing the problem you have done a great job.
