Benefits
of the Golden Section plugin

Draws the fibonacci sequences: Golden Section, Golden Spiral and Golden Triangles.
Draws the two common harmonies: Rule of Thirds and Harmonic Triangles.
Freely adjust the rectangle to any size within the image boundaries.
Rotate or flip the divisions any way you like.

The Golden Section plugin works with these image modes (Windows and Mac)...
8 & 16 bit / channel: RGB, CMYK, Grayscale, Lab, Duotone, Multichannel.

Controls

This is the Golden Section plug-ins control panel. Click on the photo or the links to the right to see the plugin at full size. The filter has four groups of controls:

1. Golden divisions
2. Harmonic divisions
3. Size (change the size of the rectangle)
4. Line thickness and darkness

Examples - golden section,
golden triangles,
golden spiral, harmonious triangles

The Golden Section plugin is the easiest and fastest way to divide your image into divine proportions for harmonious compositions

Use of filter

Transparent layer

The best way to use the filter is to create a transparent layer on the image you want to edit. In Photoshop you do this with Shift-Ctl-N. Its color should be None, which is transparent.

To get a resizable transparent golden section in Photoshop...

1. First create a new empty layer in Photoshop.

2. In the plugin draw the sections or divisions you want onto this transparent layer filling the entire image.

3. apply.

4. In Photoshop, with the golden section layer still active, select 'Free Transform' from the menu 'Edit' to resize the golden section and move it around the image.

What are the Divine Proportions?

Golden sections

Harmonious divisions

Fibonacci sequence

Leonard Fibonacci discovered that if you have a sequence of numbers beginning with 1,1, where the next number in line is the sum of the previous two, then the sequence will progress towards a more and more exact representation of the golden ratio. The fibonacci sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, etc.

Oddly enough nature tends to organize growth and limbs according to this sequence. F.ex. the ratio between the length of limbs of your fingers is the golden ratio. The ratio between the length of your nose and the distance from the bottom of the chin to the bottom of the nose is the golden ratio. The spiral growth of crustaceans follows the golden spiral. The divine proportions are an in-built (or in-grained) aesthetic parameter we judge beauty by.

The plug-ins four main control groups

Golden Sections

Here you check which divisions you want and also if you want to flip or rotate the drawing.

Flip and rotate here will also apply to the harmonious divisions.

Harmonious divisions

The most common harmonious divisions, that do not follow the golden sections, are the rule of thirds and harmonic triangles.

Size

Checking Size enables you to define a rectangle within the limits of the image. This is useful if you need to crop the image to a specific size and want to have some help.

The buttons let you set height from a specified width or width from a specified height so that the size is the golden ratio.

In each case you have two buttons to create either a landscape or portrait format rectangle from a given side.

Line

Line lets you set line thickness and line darkness. If you have a large image and have to downscale it, then a a line that's only one pixel may become invisible. You can't use colored lines, but can change it from black to white through any gray. You will rarely want to thicken the frame, but the option is there.

A few examples

Golden triangle in close ups

The golden triangles are very useful for creating dynamic close ups where the diagonal balances the two angles.

Rotated golden triangles

Golden spiral for dynamic motion
