High-index lenses are recommended if you have a high optical prescription for nearsightedness, farsightedness, or astigmatism. Lenses that contain a higher prescription, are generally quite thick and heavy. This is because the lens needs to be a certain thickness to accurately bend light to correct the refractive error.

Below is a wrap up of lighting keywords you can use in Stable Diffusion. Do you have more suggestions? Leave me a message and I will be happily updating the list.

These effects are often used to add a surreal, magical, or otherworldly quality to images. For instance, some of my favorite recipes are:

High index lenses are generally scratch resistant and can fit into almost any frame. They can also be treated with special coatings to facilitate improved vision. Many people opt for the following coatings:

Backlight, as its name suggests, comes from the back of the subject. If the subject has a certain degree of transparency, the backlight may appear as a rim light to some extent.

I love adding keywords such as movie still, deep blues, moody and ethereal atmosphere in Stable Diffusion. Still, it is not necessary to use it only for landscape AI art. For instance, when combining blue hour photography tokens with food photography or other themes, there can be surprisingly great results too.

Loop lighting creates a small shadow of the subject's nose on their cheek, forming a loop-like shape. This technique adds depth and dimension to the subject's face without creating harsh shadows, and are quite popular in portrait photography.

You can also experiment with Prompt S/R to compare different weight. Go to Script (X/Y/Z plot) > X type: Prompt S/R > input X values.

If you are still unsure about which type of lenses you are looking for, speak with your eye doctor. Your doctor is available to answer any questions you may have about purchasing new lenses.

Blue hour photography captures the mesmerizing blue that fills the sky, shooting in a short period of time before sunrise or after sunset. This is one of my favorite Stable Diffusion lighting prompts as the result feels soothing and calming.

In the past, eyeglass lenses were made of glass. However, in recent years, lenses have transitioned to a durable plastic, that is lighter in weight, and less prone to breaking— providing a more comfortable experience.

In Stable Diffision, you can combine crepuscular rays with semantically related words such as dreamlike, otherworldly, ethereal, hazy background, mystic, eerie fog, and fantasy for different atmospheres.

If you are nearsighted, your lenses will be thinner at the center and thicker on the periphery. A nearsighted prescription is written with a “minus” sign, such as -2.00 diopters (D).

Low-key and high-key photography are distinctive styles that can evoke specific moods with clean aesthetics. However, it is widely known that Stable Diffusion cannot properly handle these kind of images.

Caustics in lighting are the intricate light patterns formed when light rays interact with curved surfaces like water, glass, or shiny metal. These patterns, seen as bright shapes and lines, can add drama and visual interest to images.

Luminescent effects are light emitted from substances without heating, such as bioluminescence, phosphorescence, and fluorescence. Using it in Stable Diffusion lighting prompts can create striking visuals, such as the soft illumination of glow-in-the-dark materials, or the natural glow of fireflies and deep-sea creatures.

Lighting is the backbone of photography and illustration. It has the power to make or break a shot or a design. When generating images in Stable Diffusion, you may have encountered various challenges to control the lighting for fine results.

Note that not every technique in photography is transferrable to Stable Diffusion AI image generation. Below are some tokens that work.

One possible reason is that Stable Diffusion cannot go for images that are all dim or all bright. It tries to balance the tone somehow. For instance, if you prefer to generate a snow mountain with white roof, Stable Diffusion might give you a black roof since a snow mountain is already bright and white.

Computer lenses filter out blue light— reducing eye strain, fatigue, and headaches— and protecting your overall ocular health. Computer glasses may be purchased without a prescription. If you already wear prescription glasses, your lenses can be treated with a blue light-blocking coating.

Stable Diffusion readily presents the style when you add Golden Hour in the prompts. You can also incorporate keywords such as photorealistic, vivid colors, and sharp focus if those are in line with your imagination.

The higher the index, the thinner the lens— a lens with an index of 1.74 could be up to 50 percent thinner than a regular lens with an index of 1.5, with the same prescription.

You can add broad lighting into your Stable Diffusion prompts and adjust its weight (Broad lighting: 1.5) until you are satisfied with the results.

Aspheric lenses contain various degrees of curvature from the center of the lens to its periphery. A flatter curve allows for thinner and flatter lenses, and reduces eye magnification for farsighted prescriptions. Aspheric lenses may also improve the clarity of your peripheral vision.

High index lenses are thinner and lighter than regular lenses. These lenses are recommended for all types of refractive errors, but are ideal for those with strong farsightedness prescriptions— a thicker lens for this type of prescription generally produces a stronger magnification of the eyes. With the aspheric design of high index lenses, the center of the lens can be made thinner and create a flatter curvature— reducing the magnification of the eyes.

While both regular and high index lenses function in the same way, high index lenses are designed to bend light in the most effective way for more natural vision, and to eliminate the need for thick lenses.

Crepuscular rays, also known as god rays, are dramatic shafts of sunlight that appear to radiate from a single point in the sky. It can add depth and atmosphere to images, often creating a sense of awe or mystery.

Trifocal lenses contain three optical powers— distance, intermediate and near vision, with two segmenting lines to delineate the powers. The intermediate segment is located above the segment for near vision and is helpful for viewing objects at arm’s length, such as a computer, or car dashboard.

Iridescent lighting creates a spectrum of colors like what you see on soap bubbles, oil slicks, or the wings of certain butterflies. If you love the vibrancy and shifting of colors, you can add iridescent in Stable Diffusion prompts, together with phrases such as:

Golden hour photography is what I call the amazing twin of the blue hour. In photography, it refers to the short period after sunrise or before sunset, when the sky is lit with warm colors.

Below are some of the best lighting prompts in Stable Diffusion, followed by tutorials to use denoise offset Lora for high dynamic range images.

Hovering over the thumbnail and click on the wrench icon to edit metadata. There you can add preferred weight, description, trigger words, etc.

Using lighting prompts in Stable Diffusion is one way to control the light effects and visuals in your AI art. If you are familiar with photography lighting techniques, it will be much easier.

In digital graphics, crepuscular rays can be referred to as volumetric lighting. It is the computer graphics replication to add depth and realism to scenes. In your Stable Diffusion lighting prompts, you can experiment with crepuscular rays and volumetric lighting and go with whatever works.

You can recreate the loop lighting effects in Stable Diffusion. It may not succeed every time, but you can adjust the weight of (Loop Lighting:1.5) and arrange its position in the prompt.

512px low resolution is not enough for a 4K display or 300DPI print. When zoomed in, the image will look fuzzy and pixelated. The best solution is to use a Standalone Stable Diffusion Upscaler - Aiarty Image Enhancer.

Polarized sunglasses reduce glare from surfaces such as water and snow.  They are an ideal choice for driving and playing sports.

However, you don't necessarily need to follow the structure and include every aspect. Please note that the order of the tokens will also influence the outcome. Also, the best practice is to read the instructions of the author of a specific model. For instance, some models don't require you to include quality keywords to generate good results.

High-index lenses are thinner than regular plastic lenses because they have a higher refractive index than plastic. Plastic lenses contain a refractive index of 1.50, while high-index lenses can range from 1.53 to 1.74.

Photochromic lenses also known as transition lenses, are clear indoors and darken when exposed to sunlight. These lenses eliminate the need for sunglasses and are more convenient for those who wear glasses full time to protect their eyes from UV radiation. Photochromic lenses are technically a treatment that can be added to your prescription lenses of any type.

Bifocal lenses contain two optical powers to accommodate clear vision for both near and far. The lens is divided into two segments, the top of the lens contains the distance vision prescription, while the bottom of the lens contains the near vision prescription. Some bifocals contain a bisecting horizontal line between the two lens powers.

If you are farsighted, your lenses will be thicker in the center and thinner on the periphery. A farsighted prescription is written with a “plus” sign, such as +2.00 diopters (D).

Rembrandt lighting is popular in portrait photography. It can create compelling visuals characterized by a triangle light patch under the subject's eye on the dim side of the face (see screenshot below). The technique is named after the Dutch painter Rembrandt, known for its use in his artworks.

Note: the starting value (the first value) should be in line with what you put in the prompts. For instance, if you use in the prompts, but put as the starting line in the X value:

Tips: according to the author of this Lora, it works better when using keywords like: dark studio, rim lighting, two tone lighting, dimly lit, low key in the prompts.

To capture the flickering and twinkling appearance in Stable Diffusion, we can try to add "light particles, water drops, shimmering light, dreamy glow" whenever needed.

High-index plastic lenses are thinner, lighter, and more comfortable than regular lenses. These lenses are ideal for those with higher prescriptions, specifically those with strong farsightedness.

Since the subjects being photographed have their faces turned sideways, neither of the following two AI images can be considered broad lighting because they are both facing the camera head-on. Still, they represent the essence where half of the face is lit up than the other side.

Polycarbonate and trivex lenses are impact-resistant, thin, and lightweight. These lenses are ideal for playing sports, as they are less prone to damage. They are also designed with built-in UV protection.

Progressive lenses, also called multifocal lenses are similar to bifocals and trifocals, but contain multiple lens powers to provide vision at all distances— close up, intermediate, distance, and any other lens power necessary for vision clarity. Multifocals gradually blend the lens powers together without a bisecting line, making them more attractive than bifocals. The downside of multifocals is that the clear zone for each part of the lens may be limited.

How to better control the lighting in Stable Diffusion for low-key and high-key photography? Luckily, now we have Epi_Noiseoffset Lora.

Light shimmering, sparkling, or glimmering is often observed on bodies of water, where sunlight bounces off ripples or waves, creating a mesmerizing shimmer.

Single vision lenses are the most basic, and least expensive type of lenses. These lenses are designed for correcting vision for either near or distant clarity.

Stable Diffusion will throw at you an error saying: Prompt S/R did not find in prompt or negative prompt.

That being said, it is always a good idea to do some research before purchasing a new pair of glasses to better understand the type of glasses you will be wearing and ensure optimal satisfaction.

Prompt example: 1girl, ((pink ancient outfit)), golden jewelry, shine necklace, long red hair, high-class, palace window in backgrounground, cinematic ambient lighting, masterpiece, extreme realistic.

Besides pasting into the prompts, you can simply click the Lora tab and find epi_noseoffset together with other Lora models. Click on the epi_noiseoffset thumbnail and will be added automatically into your prompts.
