[Tutorial] Stable Diffusion For Absolute Beginner - Part 7/7

Creating Large Prints with Stable Diffusion

Go back to Part 6

Stable Diffusion primarily operates at a native resolution of 512×512 pixels for v1 models. It’s essential to maintain a balance in image dimensions. Avoid straying too far from 512 pixels in width and height to prevent duplicate subjects in your images. Here’s how to set the initial image size:

  • For Landscape Images: Set the height to 512 pixels and increase the width, e.g., 768 pixels (2:3 aspect ratio).

  • For Portrait Images: Set the width to 512 pixels and increase the height, e.g., 768 pixels (3:2 aspect ratio).

Moving on, to make larger prints, you’ll need to upscale the image. The AUTOMATIC1111 GUI, a free tool, offers popular AI upscaling options.

Mastering Image Composition

Stable Diffusion technology continually evolves, offering various methods for image composition control:

Image-to-Image

Direct Stable Diffusion to follow an input image loosely. For instance, generating a dragon using an eagle input image retains the input's composition.

ControlNet

Similar to Image-to-Image, ControlNet utilizes input images to extract specific information, such as human poses or outlines, shaping the output accordingly.

Input

Regional Prompting

Leverage Regional Prompter to specify prompts for specific image parts, aiding in drawing objects in chosen areas.

Depth-to-Image

By analyzing foreground and background in an input image, Depth-to-Image replicates these aspects in the output, maintaining their composition.

Generating Specific Subjects

Stable Diffusion proves adept at generating various subjects:

Realistic People

Utilize specialized models and precise prompts to create photo-realistic human images.




Animals

Animals remain a favored subject among Stable Diffusion users due to the platform's capabilities.



Understanding Unstable Diffusion

It's essential to note the distinction: Unstable Diffusion is a separate entity from Stability AI, the creators of Stable Diffusion AI. Unstable Diffusion garnered attention for developing models for AI-related adult content but hasn’t released any publicly available models after a Kickstarter campaign shutdown.

[Tutorial] Scenario AI: Create Consistent Characters

Image
  In this short tutorial, I will show you how to use Scenario AI, a new AI for quick and easy generating game assets. Software Scenario (free tier available) Photoshop  or Gimp (or any photo editing software) Magnific AI (optional) Pricing Scenario AI offers 4 pricing plans, including a free option, perfect for this tutorial. How to use Scenario AI Choose a model: Go to the Models tab in Scenario. Select a model that is in the vibe of the character you want to create. Don't worry about finding the perfect one yet, you can blend and remix later. Click "Generate with this model" to get a basic idea of the style. Prompt your character: Use the prompt box to describe your character, including details like age, hair color, clothing type, etc. Add prompts for front, side, and back views to ensure the model generates the character from multiple angles. Use the Prompt Builder or Prompt Spark features for inspiration if needed. Don't forget negative prompts to avoid unwanted e...
