More grey cubes, this time in groups of three. The last exercises showed that the problem areas are at the extremes of light and dark. These exercises, I think, show that the real power is in the middle values. The adjustments to compensate for the limitations of the white and black paint are the same in these grouped cubes as they were for the single cubes – except of course – that they’re all happening at once.
At the light end I have foregone the white highlight on the edge of the cube and used my white paint for the light side. The values from there down are as they are measured. At the black end I still had the problem of the shadow side of the cube being darker than my black. I painted it the same as the cast shadow. Even though I started as light as I could I still ran out of steps, it was even worse on the next painting as I will show.
Paul at Learning to See has suggested that changing the cloth for a lighter one would make these exercises more worthwhile because I’d have more steps to play with. I think he’s right (as always!).
This second example is slightly different. At the light end I chose to paint the lightest side with N9, preserving the white paint for the light highlight. This forces all the values for the white cube down a notch to compensate. The grey cube is as seen but again minus one value to be in step with the white cube.. At the black end I have run out of values and have no choice but to paint the top, the shadow side and the cast shadow all in the same black paint. The effect is still convincing. Three cubes on a dark cloth.
That’ll do for today. The others I painted were all variations on these, just moving the mid value up and down for different effects. Trying to keep the relationships so the form was convincing but under different conditions – soft light, bright light, chiaroscuro and Aussie sun…
