Rabatment.

I wonder how rabatment would look on an A3 landscape picture, and on an A5 greetings card version of it.

Can rabatment and golden ratio be used in the same picture?

If so, golden ratio of the whole picture, or of one side or other,or both, of the rabatment?

William

The grid lines added to the picture from

https://punster.me/serif/viewtopic.php?pid=3895#p3895

do not have the same result as with the stegosaurus picture, but there might be something.

The original picture is the one from the original prompt. I simply changed "an okapi" in a copy of the text to become "a stegosaurus" to explore whether Bing Chat AI would produce such a picture. In the event it produced a beautiful picture.

Here is a 1024 pixel by 1024 pixel png graphic that I have made using Affinity Designer software.

The graphic has a transparent background, with the centre lines in cyan, upon which are the thirds lines in green, and the golden lines in red.

The intended purpose is to explore what composition rules may have been used in images produced using Bing Chat Ai.

Readers are welcome to use the graphic with images generated by other AI systems, but I do not know what size they are.

William

It may be that in order to "right click download" a copy that one will first need to click on it then click on the result so as to get the full size image to download.

I produced the red lines as red filled zero width bordered rectangles 1024 pixels by 3 pixels, locating them using the centre of the 3 pixel width.

So, I consider it is worth trying with grid lines at one third and two thirds.

0.667 x 1024 = 683.008 so use 683

0.333 x 1024 = 340.992 so use 341

So, back to Affinity Designer.

William

So,

0.618 x 1024 = 632.832 so use 633

0.382 x 1024 = 391.168 so use 391

I shall now try to use Affinity Designer to make a transparent png with four red lines on it.

William

I have got to part way through page 13 of John's book.

I have learned something interesting from that.

I had heard of the rule of thirds, as in 0.333 and 0.667, but it is really golden ratio at 0.382 and 0.618.

Ah!

So more centred than thirds.

So the gap in the middle is not 0.333 it is 0.236 so much smaller.

Ah!

Yes, probably.

But at the time I was trying to get it to work at all.
