[Tutorial] Stable Diffusion For Absolute Beginner - Part 4/7

Understanding Parameters: Should You Tweak Them?

Go back to Part 3

When using online generators, you'll often find a handful of parameters you can adjust. Let's dive into some key ones:

  • Image Size: This dictates the dimensions of the output image. Usually set at 512x512 pixels, but changing it to portrait or landscape can significantly alter the image. For instance, opting for a portrait size could generate a full-body image.
  • Sampling Steps: Ensure a minimum of 20 steps. If the image appears blurry, consider increasing this value.
  • CFG Scale: The standard is around 7. Increase this to have the image align more closely with your prompt.
  • Seed Value: A seed of -1 generates a random image. Choose a specific value to reproduce the same image.

How Many Images Should You Create?

When testing a prompt, it's wise to generate multiple images.

For major prompt adjustments, I recommend creating 2-4 images simultaneously to speed up the review process. When making smaller changes, generating 4 images can enhance the likelihood of finding something usable.

Keep in mind, sometimes a prompt only works about half the time or even less. Don't dismiss a prompt based on just one image.
