Essential Requirements
Completing this guide necessitates only a single piece of software:
- Adobe Photoshop
The walkthrough utilizes Adobe Photoshop CS6; however, the methods detailed should remain effective across various Photoshop versions, including those predating CS6.
No supplementary tools or pre-existing files are required, as the entire image will be constructed directly within the Photoshop application itself.
Understanding the Core Principles
This tutorial focuses on several essential design concepts. The bokeh effect, as seen in photography, originates from out-of-focus points of light.
These points of light adopt the shape dictated by the lens's aperture. Simply generating circles won't suffice to replicate this effect accurately.
Replicating Photographic Depth
To authentically reproduce bokeh, we must simulate the depth present in a real photograph. This means the light points shouldn't all exist on a single focal plane.
Furthermore, natural bokeh exhibits variations in light size. A uniform arrangement of identically sized circles would appear artificial and lack realism.
Our Approach to Creation
To streamline the process and avoid repetitive manual work, a custom brush will be developed. This brush will be specifically designed for creating circles of varying sizes.
Multiple layers, each containing these variable-sized circles, will then be combined. This layering technique is crucial for generating the desired illusion of depth and a natural bokeh appearance.
Ultimately, this method allows us to efficiently construct a visually compelling bokeh wallpaper.
Creating and Configuring Your Bokeh Brush in Photoshop
Initially, the task involves establishing a workspace and crafting a simulated Bokeh brush within Photoshop. Begin by creating a new image with dimensions matching your desired wallpaper size. For standard screen resolutions, 1920x1080 pixels is commonly used. Ensure the background is set to transparent.
After the new canvas is generated, select a foreground color that is a very dark gray, avoiding pure black. An RGB value of 30-30-30 serves well for this purpose.
With the dark gray selected, choose the Ellipse Tool (U) from the Shape Tools. Maintain a circular aspect ratio by holding the Shift key while drawing a circle in the canvas center. A diameter of approximately 300 pixels is suitable for a 1920x1080 canvas, though the size can be adjusted later for optimal visibility and editing.
You will now have a dark circle centered on your canvas. To modify this circle, double-click its layer entry in the Layers panel. Adjust the Fill Opacity to 50%, ensuring you are modifying the Fill Opacity and not the overall Opacity. Then, add a pure black Stroke with a width of 10 pixels and 100% opacity, as shown below:
The resulting image should resemble the one above: a circle with a black outline and a semi-transparent center, evoking the appearance of a camera lens filter.
This circle will function as the foundation for our brush. To define the brush preset, navigate to Edit -> Define Brush Preset. Assign a descriptive name to the brush; for example, "Bokeh Brush 1".
Following the naming process, the Brush/Brush Presets panel will appear on the right side of the screen. Select the Brush Tool (B) from the toolbar, then click on the Brush Presets tab. Locate and choose your newly created brush:
Once selected, access the Brush tab to view and adjust the brush's properties. The preview window at the bottom displays a sample brush stroke with the default settings.
This default appearance doesn't yet capture the soft, natural effect of bokeh. To rectify this, adjust the spacing within the Brush Tip Shape settings. Change the spacing from 25% to 100%, observing the corresponding change in the brush preview:
To achieve a more randomized distribution of circles, increase the scatter value. Navigate to the Scattering settings and set Scatter to 10,000%, Count to 5, and Count Jitter to 1%. Experimenting with these values later can yield unique effects.
The preview now begins to resemble the random, overlapping points of light characteristic of bokeh photography.
Introduce size variation by accessing the Shape Dynamics settings. Set Size Jitter to 100%, Control to Pen Pressure, and Minimum Diameter to 50%, leaving other settings at their default values.
The addition of Size Jitter enhances the variation, creating a more natural look. Finally, adjust the Opacity and Flow Jitter in the Transfer category. Set Opacity Jitter to 50% and Flow Jitter to 50%, and change the Control for Flow Jitter to Pen Pressure, leaving other settings unchanged.
The brush preview now displays a beautiful, bokeh-like effect, hinting at the potential of the wallpaper to be created.
With the brush defined, the next step is to begin creating the actual wallpaper.
Establishing the Background Gradient and Bokeh Layers
Begin by generating a new layer within your Photoshop workspace. If desired, you may disable or remove any previously used layers, such as the one utilized for the ellipse brush. Designate this new layer as "Background". A solid color or a gradient can be applied to the background of your wallpaper on this layer; however, gradients generally produce a more visually appealing outcome.
Utilize the Gradient Tool (G) and either select a pre-defined gradient or construct a custom one. The existing presets did not offer the intensely vibrant rainbow effect desired, so a new gradient was created employing the following seed values for gradient locations: 0% at 255-0-252, 50% at 0-252-255, and 100% at 240-255-0.
When applied at approximately a 35-degree angle extending from the lower left to the upper right corner of the canvas, the gradient will appear as follows:
Once the canvas is painted, the creation of the initial bokeh layer can commence. Establish a new layer named "Bokeh Background". Activate the Brush Tool (B). Set the brush color to pure white.
Choose a brush size that is roughly one-third to one-half the vertical dimension of your canvas. For a 1920 x 1080 canvas, this translates to a brush size of approximately 300-500 pixels. A size of 500 pixels will be used for this example.
The subsequent step, and its repeated application, is largely dependent on personal preference. Begin with a light touch, gradually increasing pressure if desired. It’s important to remember that this brush generates a broad and variable stroke, unlike a standard brush with immediate visual feedback.
Initiate a brush stroke spanning the canvas, then add additional circles as needed. Two complete passes, one from left to right and another from right to left, generally yield satisfactory results. The canvas should now resemble the following, with some variation in circle placement:
As this constitutes the background layer, a blur is necessary to establish a sense of depth. While still on the "Bokeh Background" layer, navigate to Filter -> Blur -> Gaussian Blur. A value between 20 and 30 pixels will produce a pleasing background blur.
The process must now be repeated with minor adjustments. Create a new layer called "Bokeh Midground". Reduce the brush size to a smaller value (in this case, from 500 pixels to 300 pixels). Apply the brush tool across the canvas until the desired number of circles is achieved. Re-apply the Gaussian Blur, but this time with a setting between 5 and 10 pixels.
The addition of the second layer is visibly enhancing the wallpaper’s form. A final layer is now required. Create a new layer named "Bokeh Foreground". Further decrease the brush size (from 300 pixels to 150 pixels). Repeat the brush stroke across the canvas. Apply the Gaussian Blur once more, reducing the value to 1-5 pixels.
This concludes the tutorial; after blurring the "Bokeh Foreground" layer, the final result will be revealed:
The workflow’s simplicity allows for rapid creation of new wallpapers with varying densities of circles, gradient colors, and other customizations.
Furthermore, without repeating the entire process, a new layer can be added over the existing background, a new gradient applied, and a wallpaper with a completely different aesthetic created:
The inherent variability and randomness of the outcome contribute to the enjoyment of this project. Experiment with brush sizes, settings, and other parameters to achieve unique and compelling results—and share your creations with other readers in the comments section.
