Making sense of the value scale is part of training our eyes to discern value changes, - the more we do it, the more sensitive and accurate our value choices will be. - but WHY?
Because VALUE is how we show form and create the illusion of 3 dimensions, on a flat canvas.
Does your work have depth, or show the light effects that you desire? We avidly study COLOR, but VALUE is what gives COLOR it's power - with out it, color makes little sense.
So - this week we started with a color photo of a cup and saucer and created a few 3-value plans - to which we applied this criteria:
The value plan must show the light & shadow effect.
It must help me to communicate what I want to say about the photo?
The value plan must communicate the 3D structure of the image in the photo?
To keep it simple we started with Black as #7 and laid in the darkest areas, then mixed a mid range gray (matching it to #4 on the Grayscale) and applied it to all of the middle value areas. Finally we left the white of the canvas as #1 our lightest value.
Of the 3 above - each value plan is a little different.
We used the photo for reference, but have made different design choices as to where certain lights and darks will be placed.
So much for the easy part. . .

In the case above - I have tried to work many colors into each of the three values, but the true test is when we look at a tonal interpretation to see if they all hang together as one value. See below.
At first I did not trust my own eyes as I squinted to match colors to values.

Your trained EYE can still be the best judge of visual information - so grab that grayscale -
you are now free to start squinting at the world.
