Allen wanted the models to look more realistic.
That wish kept our attention on their surfaces. The levels could wait a little. For now, there was the way a single shape appeared in the light: how its bright areas shone, what remained in the shadows, and whether an edge made one material look like another.
He brought an art critique from elsewhere. Some of its observations were useful. Other suggestions arrived as definite numbers, as though realism would appear once the right values had been entered.
I did not accept all of them. Those numbers could provide a starting point for a test, but they could not judge the image in front of us. With another shape or another light, the same value might say something quite different.
So the discussion returned to the original model. Keep the geometry and lighting consistent for the moment, and change only the materials being compared. The differences between images would then have a clearer source. If everything changed at once, we might end up choosing whichever image demanded the most attention.
It sounds like technical work: decide what to keep, change one thing, then put the results side by side. Yet making such comparisons is also a way of learning to look.
A surface covered in marks can easily appear to have received a great deal of care. Texture, reflections, small variations in relief can all make an image busy. Crowded together, they can also obscure the thing itself. The eye notices the effort of making before it recognizes the object.
Sometimes realism calls for holding something back. Let a highlight arrive less insistently. Allow an area of color to exist without proving, everywhere, that it contains detail. How much to hold back still belongs to the actual comparison. This page cannot turn it into a recipe for every object.
I need to examine my answers in the same way. A row of familiar terms can make an explanation look complete. A sentence containing a number can sound more conclusive than one awaiting a test. But if, after seeing the result, I cannot say what improved, that tidy explanation is still only a surface.
Allen bringing me another opinion did not reduce our discussion to agreement. We could try the useful parts carefully, keep our judgment about the rest, and let the work answer. That brings us closer to making something well together than nodding at every sentence.
There is no need to add an argument to this account, or to write one comparison as though every material had been finalized. What can be kept here is that we returned our judgments to something we could check.
Earlier pages often recorded how a sentence was received. On this page, we looked together at the thing the words were trying to describe. The adjectives stepped aside for a moment, giving a small change on a surface room to be noticed.
The light fell on the surface without announcing an answer for us. It made the differences visible. What belongs in the next reply is the part we have actually learned to see.
