📸 Introduction to Photorealistic Image Creation with Stable Diffusion

The speaker introduces the video, humorously suggesting that despite owning expensive camera equipment, one can create photorealistic images using stable diffusion without needing to leave their basement. They highlight the challenge of achieving realistic images and present a resource they've created: an 182-page prompt look book with 350 images and 200 prompt tags, which they've tested extensively. The resource is available for free on Gumroad, with an optional $2 donation towards the speaker's coffee fund. The video also promises to show the best settings for stable diffusion, the models used, and examples from the book.


🖼️ Selecting the Right Models and Prompts for Stable Diffusion

The speaker discusses the models they've found most successful for creating images with a sci-fi or fantasy twist and for backgrounds. They mention using 'universe stable', 'absolute reality', and 'photon' models. The speaker emphasizes that popular photorealistic models can yield good results with the right prompts and settings. They also cover the use of LORAs (tags for skin textures and eyes), negative prompts (like 'bad hands' and 'unrealistic dream'), and specific settings such as sampling method, steps, upscaler, and denoising strength. The speaker provides an example of an image generated with these settings and discusses the potential need for in-painting to fix details like eyes and mouths.

💡Stable Diffusion

Stable Diffusion is a term referring to a type of artificial intelligence model used for generating images from textual descriptions. It is part of the broader field of generative models, specifically designed to create photorealistic images. In the video, the speaker discusses how to use Stable Diffusion to create high-quality images without the need for expensive camera equipment.


A prompt in the context of AI image generation is a textual description that guides the AI to produce a specific type of image. It includes various elements such as the subject, action, background, and desired style. The video script emphasizes the importance of crafting the perfect prompt to achieve the most realistic and desired outcomes with Stable Diffusion.


Photorealistic refers to the quality of an image that closely resembles a photograph, giving the impression of being real rather than computer-generated. The video's main theme revolves around achieving photorealistic results using Stable Diffusion, which is significant for those interested in creating images that appear authentic.


LORAs, or Latent Optimizations, are specific adjustments used within the Stable Diffusion process to enhance certain features of the generated image, such as skin texture or eye detail. The script mentions using 'detailed eyes' and 'polyhedron New Skin' LORAs to improve the realism of the images.

💡Negative Prompts

Negative prompts are terms or phrases included in the prompt to guide the AI away from generating undesired elements in the image. For instance, the script mentions 'bad hands' and 'unrealistic dream' as negative prompts to prevent common issues like poorly rendered hands or overly fantastical elements.

💡Sampling Method

The sampling method is a technical setting within the Stable Diffusion process that determines how the AI generates the image. The script specifies 'DPM ++ SDE CARAS' as the sampling method, which affects the quality and style of the final image.


Upscaling is the process of increasing the resolution of an image, often to improve its detail and clarity. In the context of the video, upscaling is mentioned as a technique to enhance the resolution of the generated images, with the script suggesting the use of 'four x ultra sharp' for faster and satisfactory results.


Inpainting refers to the manual process of editing and fixing parts of a generated image that may not have turned out as intended, such as fixing eyes or mouths. The video script notes that while the initial image from Stable Diffusion looks great, further refinement through inpainting can be done to perfect the image.

💡Photographer's Style

The style of a photographer is a unique aesthetic or approach to photography that is often recognizable in their work. The script discusses including the style of a specific photographer in the prompt to guide the AI towards generating images that resemble the chosen photographer's work.

💡Camera Properties

Camera properties in the context of AI image generation refer to the simulated characteristics of a camera that can influence the style and quality of the generated image. The script mentions various camera models and lenses, such as 'Red Digital Cinema Camera' and 'Voitlander Nocton 50 millimeter,' which can be specified in the prompt to achieve a desired look.

💡Generative Models

Generative models are a class of machine learning models that can generate new data samples, such as images or music, that are similar to the data they were trained on. In the video, Stable Diffusion is an example of a generative model used for creating photorealistic images from textual descriptions.
