After purchasing a DSLR, I decided to make a ‘notes’ file to store photography information and tips. For example, this file contains settings that can be used to shoot ‘smooth / silky’ waterfalls.

To manage the information, I followed a hierarchical method, with the main topic being the top level node and its related information arranged in a hierarchy below it.

Each block of information is separated by forming a ‘line’ using ‘=’ or ‘-‘ or ‘*’ characters.

Let me illustrate with a suitable example. I wanted to store the following information, relating to usage of the ‘Unsharpen Mask Filter’ in many photo editing tools.

Arrangement 1

Initially, I stored the information using free form text, as below

Unsharp Mask filter.

In order to do its job of sharpening, the Unsharp Mask filter increases the contrast between adjacent pixels.
To control the level of contrast, you will choose settings for three variables: Amount, Radius, and Threshold.
For an image that is 2000 x 3000 pixels or larger, try using these values.
For Soft-edged subjects, such as landscapes - Amount: 100–150%; Radius: 1–1.5; Threshold: 6–10.
For Portraits - Amount: 100–120%; Radius: 1–2; Threshold: 4–6, or to the point that skin areas begin to look smoother.
For Buildings, objects, etc., for which contrast is a priority - Amount: 150–200% or higher; Radius: 1.5–3; Threshold: 0–3.

Note: Please note that for each of the examples, I have replaced the ‘tab’ character with four spaces, for publication only.

Arrangement 2

Then, I used a tabbed method of storage, as below

    Unsharp Mask filter
        In order to do its job of sharpening, the Unsharp Mask filter increases the contrast between adjacent pixels.
        To control the level of contrast, you will choose settings for three variables: Amount, Radius, and Threshold.
        For an image that is 2000 x 3000 pixels or larger, try using these values:
            Soft-edged subjects, such as landscapes
                Amount - 100–150%
                Radius - 1–1.5
                Threshold - 6–10
            Portraits
                Amount - 100–120%
                Radius - 1–2
                Threshold - 4–6, or to the point that skin areas begin to look smoother
            Buildings, objects, etc., for which contrast is a priority
                Amount - 150–200% or higher
                Radius - 1.5–3
                Threshold - 0–3

Arrangement 3

With the file growing in size, I realized that using tabs only was the weak point of the structure as an mess / deletion of tabs would mix up all information. Hence I started using bullet points in a text file, as below

    [*] Unsharp Mask filter
        [@] In order to do its job of sharpening, the Unsharp Mask filter increases the contrast between adjacent pixels.
        [@] To control the level of contrast, you will choose settings for three variables: Amount, Radius, and Threshold.
        [@] For an image that is 2000 x 3000 pixels or larger, try using these values:
            [#] Soft-edged subjects, such as landscapes
                [$] Amount - 100–150%
                [$] Radius - 1–1.5
                [$] Threshold - 6–10
            [#] Portraits
                [$] Amount - 100–120%
                [$] Radius - 1–2
                [$] Threshold - 4–6, or to the point that skin areas begin to look smoother
            [#] Buildings, objects, etc., for which contrast is a priority
                [$] Amount - 150–200% or higher
                [$] Radius - 1.5–3
                [$] Threshold - 0–3

Arrangement 4 (Current)

After making the hierarchy 6 deep, I realized that I was running out of decent symbols. Hence I switched to using numbers in the bullets, instead of symbols. Thus, each number essentially denotes it’s position in the hierarchy, as below

    [1] Unsharp Mask filter
        [2] In order to do its job of sharpening, the Unsharp Mask filter increases the contrast between adjacent pixels.
        [2] To control the level of contrast, you will choose settings for three variables: Amount, Radius, and Threshold.
        [2] For an image that is 2000 x 3000 pixels or larger, try using these values:
            [3] Soft-edged subjects, such as landscapes
                [4] Amount - 100–150%
                [4] Radius - 1–1.5
                [4] Threshold - 6–10
            [3] Portraits
                [4] Amount - 100–120%
