How to shade, render, paint values drawing lesson, white cubes exercise for artist. Part 1 of 3

How to shade and render drawing lesson, white cubes gray scale exercise for artist. It is part one of the three cubes exercise. They are one white cube, one black one, and one a mid grey.

The first stage was to paint each one in isolation, starting with the lightest value, white, cube. This should be the easiest, since I know I can hit all the values I see within the available range of my oil paint. Step by step how to start sketching the initial idea, drawing, blocking in shape, background and rendering. Learn how to render and see value from the real object and apply it into your painting, illustration and concept design.

Here is Definition of Value as Munsell's Explain it.

Value, or lightness, varies vertically along the color solid, from black (value 0) at the bottom, to white (value 10) at the top. Neutral grays lie along the vertical axis between black and white.

Several color solids before Munsell’s plotted luminosity from black on the bottom to white on the top, with a gray gradient between them, but these systems neglected to keep perceptual lightness constant across horizontal slices. Instead, they plotted fully-saturated yellow (light), and fully saturated blue and purple (dark) along the equator.

Chroma (Hue, color)

Chroma, measured radially from the center of each slice, represents the “purity” of a color, with lower chroma being less pure (more washed out, as in pastels). Note that there is no intrinsic upper limit to chroma. Different areas of the color space have different maximal chroma coordinates. For instance light yellow colors have considerably more potential chroma than light purples, due to the nature of the eye and the physics of color stimuli. This led to a wide range of possible chroma levels—up to the high 30s for some hue–value combinations (though it is difficult or impossible to make physical objects in colors of such high chromas, and they cannot be reproduced on current computer displays).

*As shown in the exercise, you must put the medium gray cloth as background to get the most out of the exercise.

My Photoshop palette made from Munsell's value scale:


Here is an example of one of Munsell's scales:


TOOLs You'll need: *home made edition :)
And here is a printout of "white cube" (if you cannot find wooden cube)
Print this out on a thick piece of paper then fold them together you can create a box or cube for your exercise: (click on a bigger version, then right click to save...then print it!)

Here are some tool to help you compare values on the cube while painting:
Click to enlarge. Save it then print out on a thick piece of paper.
Then cut them up into 10 pieces also cut off the circle hole to see thru.
Instruction is as in the pic below it.


Use each one to compare the value of the cube or any object, then you will really find out how dark it really is or how light it really is.

Using the value tool while you paint and study values

Part III are coming soon...one at the time.
