I'd like to do a better job of addressing this point. Lets take a look at the usual suspect:Ken Olson wrote: ↑Tue Apr 30, 2024 5:58 pm When I look at the image of the character from III 13 with the naked eye, I see what appears to be a slight indentation, if that's the word for it, and I think perhaps AdamKvanta perceives it too. It seems to be preserved in the the early stages of your analysis, both in some of your earlier posts and this one, but then disappears in the third and fourth stage. This makes me think the image manipulation might be manipulating the image a bit too much.

On the left is the cropped version from Ken's post, on the right is the hi-quality image. As of old, our primordial bugaboo of bad quality images of dubious origin are hurting us here. The low-res image is *really* low res. You can see the giant pixels. And when we move to the high-quality image, the indent is much more subtle.
i'm trying to get some good way to visualize my next point, but my software is not cooperating......recall, the theory is that under the nib there should be the most ink, and therefore, the areas should be the darkest. So, to prove that the indent is due to ink diffusing, and not due to an extra stroke, we should be able to just progressively remove the lighter pixels, and see if they disappear before the main stroke does.
I made a very bad animated gif of the process here: .
But really, it needs more frames and to be slowed down to really pop.......but if you have photoshop or something, you can just try it yourself. find a way to progressively remove the faintest pixels, and see what you find. Here's what the still image looks like, when you've eliminated all pixels which are fainter than the path I reconstructed:
As you can see, if you delete the faintest pixels---presumably the ones due to ink diffusing away from the nib--you see that the final stroke doesn't have any indents or kinks or anything. Its just a very smooth stroke.
BTW, all of the images in this post are derived from the unprocessed images. I haven't filtered, shaked, or baked them. Just took the original image and started to remove faint pixels. If you have got a halfway sophisticated image processing application, you should be able to just reproduce it for yourself.
