Golden ratio

The golden rectangle and the golden spiral have been used throughout history for art and architecture. You can now make your own golden ratio grids.

Save the three images below and follow the instructions to create your own golden ratio grids.

========

Golden rectangle
59497

Golden Spiral (clockwise)
59498

Golden Spiral (counter clockwise)
59499

========

Launch ArtRage

Click File>Import Image File

Select one of the golden ratio files from above.

Click on the Selection tool or Click on Tools>Select Tool>Selection

Select Magic Wand

Select Mode = Replace

Click a section of the white area

Press the Delete key or click Edit>Clear

Do this for all the white space. You should see something like the image below.

59500

Click File>Save Painting

Give the painting a nice name

========

Now when you want to use the golden ratio girds, do the following.

Click File>Import Image File to Layer

Select the golden ratio painting you just saved

The golden ratio file will be on a separate layer. Make sure you don't paint on that layer.

The layer can be rotated and scaled, but don't stretch them. That would change the golden ratio.

Excellent! and great instructions. Grabbed and noted. Thank you!

Edit:


The layer can be rotated and scaled, but don't stretch them. That would change the golden ratio.


If we can't stretch them, can we paint on anything bigger than a 300x canvas, the size of these images?

You can paint things bigger or smaller than the size of the original golden ratio image. You just need to scale the golden ratio image to whatever size you need. Make sure you grab the handles on the corners to make it scale horizontal and vertical at the same time.

What you don't want to do is stretch or shrink from side to side or up and down. An example is in the image below.

The workspace is 800x600. The original golden spiral is on at the top of the workspace. The stretched golden spiral is at under the original golden spiral.

If we can't stretch them, can we paint on testo-max https://www.tenderbuttons.com/testo-max-review-results anything bigger than a 300x canvas, the size of these images?


Excellent post Fugu, I love it when maths and art are combined.
