Lens Flare - Use glare as a design element

[stable wing]

Lens flare is an artistic technique that occurs when light directly hits the camera lens, causing reflections and scattering of light within the lens elements. This effect can create bright, streaking lines or halos of light, often seen in photography and cinematography. Lens flare is used to add a sense of realism, enhance the mood, or draw attention to specific parts of an image. It can evoke feelings of warmth and nostalgia, especially in scenes with strong sunlight or artificial lighting. While sometimes considered a technical flaw, lens flare is often intentionally incorporated by artists to add visual interest and a dynamic quality to their work.

Example from ChatGPT 4o conversation on lens flare

• cinematic scene of a galleon on the high seas, with the sun off-center to the right creating a dramatic lens flare. The warm sunlight casts a glow over the waves and the ship, enhancing the sense of adventure in the air. The galleon, with its sails billowing, evokes a feeling of exploration and excitement, while the lens flare adds a dynamic, realistic touch to the scene.

Requests for lens flare often result in a point light source casting light in a symmetrical pattern. You can take advantage of that behavior of the model by asking for lens flare as a design component in non-photographic media. Here is an example:
• Art Nouveau fairy casting a beam of lens flare, depicted in a whimsical and elegant style with a pastel palette. The lens flare appears as a soft, glowing beam, enhancing the magical and enchanting atmosphere. The fairy is graceful and ethereal, surrounded by delicate, flowing lines and patterns typical of Art Nouveau design, creating a light and airy composition that emphasizes the beauty and magic of the scene.

Here is a side-by-side comparison of different lens flare shapes:

Star-shaped Flare: A bright light source creating a starburst effect with multiple points.
Circular Flare: A bright light source creating smooth, circular flares.
Hexagonal Flare: A bright light source producing hexagonal flares.
Custom Heart-shaped Flare: A bright light source creating a heart-shaped flare using a custom aperture mask.
Each shape is distinctly represented to show how different lens configurations and modifications affect the appearance of flares. ​

One example : A bright light source creating smooth, circular flares in a cityscape at night. The image should capture a streetlight causing concentric circles of light, with the city skyline in the background. The circular lens flare should be prominent, adding a dynamic and artistic touch to the nighttime scene.

Ghost flare, also known as lens ghosting or ghosting flare, is a type of lens flare that appears as a hazy, pale area in a photograph, which may repeat itself along a straight line. It's caused by light reflecting off the surface of a lens repeatedly, usually when there's a strong light source in the frame, such as during backlight. The reflections can occur in front of and behind the lens' aperture, giving the ghost the same shape as the aperture. Ghost flares can add a sense of mystery and beauty to photos especially when it is combined with the bokeh effects (see #1225215231777832961 message).

I used the following base prompt for attached images: “Professional photography, a closeup view of [object], [situation], [lighting], with the ghost flare, which manifests as a pale, hazy area in the image. Shallow depth of focus, background in bokeh." [Note: It's a good idea to incorporate a brief description of the specific kind of flare we want. Otherwise, DALL-E (via ChatGPT 4o) seems to tend toward starburst pattern, which is the most common type of lens flare.]

Image 3: A magnolia flower, bright natural light.

Controlling lens flare variables in AI art: lens flare intensity

The way we choose to use lens flare can make a big difference in the outcome. In this case, let’s focus on high vs. low intensity:

Here are two images of a futuristic cityscape at dusk with a more significant difference in lens flare intensity:

1.    The first image features an extremely high-intensity lens flare, creating bold halos and dramatic streaks of light.
2.    The second image features a very low-intensity lens flare, with much less  noticeable halos and fainter streaks of light.

To create a significant disparity between high-intensity and low-intensity lens flare images, the prompts need to clearly specify the differences in intensity and visual impact of the lens flare. Here’s how you can craft and modify the prompts to reflect both versions:

High-Intensity Lens Flare Prompt:

“A futuristic cityscape at dusk, where towering skyscrapers with neon lights cast reflections on the streets below. An extremely high-intensity, warm-toned lens flare from the setting sun dominates the center of the image, creating bold circular halos and dramatic streaks of light across the buildings. The scene is bathed in a mix of natural and artificial light, with the lens flare adding a striking and dynamic atmosphere.”

Low-Intensity Lens Flare Prompt:

“A futuristic cityscape at dusk, where towering skyscrapers with neon lights cast reflections on the streets below. A very low-intensity, warm-toned lens flare from the setting sun subtly enhances the center of the image, creating barely noticeable halos and faint streaks of light across the buildings. The scene is bathed in a mix of natural and artificial light, with the lens flare adding a touch of realism without overpowering the image.”

These examples illustrate how the intensity of lens flare can drastically alter the visual impact and atmosphere of an image. (Images and presentation created with Dalle3 via ChatGPT4)

A comparable and related light-based optical phenomenon to lens flare (occurring via light refraction) happens in many space telescope images (occurring via light diffraction). This effect, which results from light moving around obstacles, creates the iconic spiked star shapes in images of distant astronomical bodies. For example, the recent James Webb Space Telescope has a mirror supported by three struts, each of which produce two spikes rotated 90 degrees, for a total of six spikes for each bright star. Meanwhile, Hubble images feature cross-shaped stars, sometimes with an extra set, creating an eight-pointed look.

Prompt: "Space telescope imagery of a realistic vast star field. Each star is formed by eight small pointed spikes. Pastel dusty effect. Beautiful illustration."

Incorporating lens flare in a landscape painting can add a dynamic and realistic touch to your artwork, creating a sense of light and atmosphere that can make your pieces more engaging and visually striking. Lens flare should enhance, not overpower, your artwork. Use it sparingly to maintain a balance between realism and artistic expression. Look at works by Impressionist painters like Claude Monet, who captured the effects of light and atmosphere, often with a sense of glowing luminosity that can inspire your use of lens flare.

I had a discussion with ChatGPT 4o about the use of lens flare effects in painting and then used this base prompt: "Create an Impressionist landscape painting, depicting a reflective pond in the woods in early summer, with a cluster of water lily flowers. Loose, soft brushstrokes, abstract shapes, carefully blended colors to emphasize the subtlety of early morning light at dawn, use lens flare effects to enhance ambiance."

A fun mash-up with a previous theme, Rembrandt-style lighting! #1202375301888348210 messageA portrait of an old man in the style of Dutch Golden Age painting. The man has a weathered face with deep wrinkles, wearing traditional 17th-century clothing. The lighting is Rembrandt-style, with dramatic chiaroscuro creating deep shadows and bright highlights. A lens flare effect adds a modern touch to the classical portrait.Interesting to see how much lens flare makes the output lean toward photorealistic, even with the painting style specified first.
