While using Photoshop one day, I may have stumbled onto an understanding of the faint pictures that we see in our mind's eye of imagination when picturing something.
I also read somewhere about this imagination using parts of the visual system, but, of course, not the retinal part itself, but the portions further in.
It seems that these images in the mind have about 80-90% transparency, as one can do in Photoshop, making them faint, which I suppose is a necessity so that they are not confused with images from the real world.
I note, too, that they have a duration, for if you try to keep seeing them, they eventually fade away.
Also, filling in a wide scene with parts like birds or such seems to have to be built part by part.
What this understanding is good for, I don't know.
If only we could lessen the transparency we could see some great stuff!
But, as usual, tampering with something like that might produce side effects in something somewhere else.
