Take any photo one of your own or found on the internet (I prefer public domain images so i don't run into copyright issues).
Try to crop/edit compose using the Fibonacci spiral or the Phi grid (It is said that our brain is hard-wired to see these because of patterns that exist in nature so it's pleasing to the eye).

I'll start...here i used the Phi grid on one of my photos.

I have a fibonacci spiral scm but what and where is Phi filter.

i don't know i just made my guide. I use this
and just put it as 50 opacity (or around there) and scale it and move it or flip it.

Thanks Tran.

I found the Phi script at the registry.
Called Golden ratio/Phi grid.
I put it in my scripts folder and restarted gimp but I cannot find it anywhere.

It's under Image->Guides->New Guides _Golden Ratio.
But what this does is create guides over top of your image and it doesn't create guides for borders.
I don't know how useful this will be for me as I don't know how or if you can resize all guides at the same time and move them all at the same time.
I can move the image around i guess. but this might need to create borders as well so that you know where to crop.

I decided that I would add guides for borders of image as well with the below script
.
So that now once the guides are created, you can just scale/move layer around to fit the golden rule while seeing borders as future crop of area.

Another very useful filter by Ofnutz.

Ofnutz Golden Spiral Script can be found here.

Creates a golden spiral path inside the selection bounds. Mostly useful as a poor man's Golden Spiral guide to crop pictures.

golden-spiral

This script generates a "golden spiral" with the rectangle that bounds the selection. It is intended mostly as a substitute for a golden-spiral guide when cropping photographs.
Usage

Unlike most scripts here, the menu entry for this script is in the "<Image>/Select" menu (at the bottom).

The golden spiral is generated with the following rules:

The external limit of the spiral starts on the selection bounds rectangle.
The spiral is drawn inside a golden rectangle whose smallest side is the smallest side of the selection bounds

To avoid clutter in the Paths list, a new golden spiral path will replace the previous one (rename the previous one if you need to keep it).

The script dialog allow one to specify:

The position of the spiral center in the rectangle
The optional rendering of the enclosing golden rectangle.

cool script

for the Phi grid...
here are the steps to use Gimp's built-in golden sections.

1) Select/All
2) select/To Path to get a path that is the border/frame of image.
3) then under scale's Tool Options, and under "Guides", select "Golden Sections" (I think it's defaulted as "Number of lines").
4) Now if you scale the path, you'll see golden sections/phi grid instead of the default grid lines.

Sweet huh? I think it's awesome that it's already built-in.

Cool...that video was interesting, I have to go watch the rest of it.

Hi everyone,
found this topic while searched for golden ration guides plugin. I was not able to find one, so I've created it, hope someone will find it useful
(Seems like forum rules doesn't allow me to post link to the script, so I've split it)
