Keywords

💡Stable Diffusion

Stable Diffusion is a term used to describe a type of artificial intelligence model capable of generating images from textual descriptions. It is central to the video's theme, as the speaker discusses the process of creating photorealistic images using this technology. The script mentions using Stable Diffusion to create images 'in your bedroom or basement,' highlighting its accessibility.

💡Prompt

In the context of AI image generation, a 'prompt' is the textual description or set of instructions given to the AI to guide the creation of an image. The video emphasizes the importance of crafting the 'perfect prompt' to achieve desired results with Stable Diffusion, and the speaker shares insights from their 182-page prompt look book.

💡Photorealistic

Photorealistic refers to images that closely resemble photographs, exhibiting a high level of detail and realism. The video's main message revolves around achieving photorealistic results using Stable Diffusion, as evidenced by the speaker's demonstration and the resources provided in their prompt look book.

💡LORAs

LORAs, or Latent Optimization for Realistic Art, are a technique used within AI image generation to enhance specific features of an image, such as skin texture or eyes. The script mentions using 'two LORAs' in prompts to achieve more realistic results, underscoring their role in fine-tuning image details.

💡Negative Prompts

Negative prompts are terms included in an AI image generation prompt to exclude certain elements or qualities from the resulting image. The video script provides examples such as 'bad hands' and 'unrealistic dream,' which are used to guide the AI away from generating undesirable features.

💡Sampling Method

The sampling method in AI image generation refers to the algorithmic process used to select and combine elements from the latent space to create an image. The script specifies 'DPM++ SDE CARAS sampling' as the preferred method for generating images, indicating a technical aspect of the process.

💡Upscale

Upscaling in the context of image generation is the process of increasing the resolution of an image while maintaining or improving its quality. The video discusses using 'four x ultra sharp' to upscale images for better clarity and detail, emphasizing the importance of resolution in achieving photorealism.

💡Denoising

Denoising is the process of reducing or removing noise from an image to enhance its clarity. The script mentions adjusting 'Denoising strength' as part of the image generation settings, highlighting its role in refining the final image quality.

💡Inpainting

Inpainting is a technique used to fill in or correct parts of an image, often used in AI-generated images to fix imperfections like incorrect facial features. The video mentions using inpainting to address issues with the generated image, such as fixing the eyes and mouth.

💡Style of Photography

The style of photography refers to the artistic approach or visual language used in creating images. The video script discusses various styles such as 'candid photography' and 'surrealist photo' as part of the prompt to guide the AI in generating images with specific aesthetic qualities.
