Img2img Tutorial for Stable Diffusion.
Education
Introduction
Welcome to this tutorial on using image-to-image (img2img) functionality in Stable Fusion. In this tutorial, I will guide you through how it works and share some tips and tricks along the way. So let's dive into the tutorial!
Introduction to Image-to-Image
Image-to-image is a feature in Stable Fusion that allows you to transform and modify images. It analyzes the colors in the input image and applies those colors to the output image while retaining the overall composition. It works with various types of images including stable Fusion-generated images, mid-turn generated images, photos, and paintings.
Getting Started with Image-to-Image
To begin, let's start with a regular image-to-image conversion. You can load an image, such as a picture of a woman with blue hair, into the image-to-image workspace. It's important to note that the denoising strength setting plays a crucial role in determining how much of the input image gets transferred to the output image.
Understanding Denoising Strength
The denoising strength setting determines the degree of change introduced into the output image compared to the input image. A value of 0 will retain the original image, while a value of 1 will dramatically transform the image. To achieve desired results, it is recommended to set the denoising strength between 0.4 and 0.7. This range strikes a balance between retaining the original image and introducing changes. Experimenting with different values will allow you to fine-tune the output to your liking.
Iterating on Images
To further refine your output image, you can iterate on the process by continuously adjusting the denoising strength and generating multiple images. By incrementally increasing or decreasing the denoising strength, you can gradually introduce more or fewer changes into the image. This iterative approach enables you to refine the output image while maintaining the overall composition and desired changes.
Combining Image-to-Image with Inpainting
In addition to the image-to-image feature, Stable Fusion offers inpainting capabilities. Inpainting allows you to selectively mask areas of the image and make changes within those masks. By using inpainting in conjunction with image-to-image, you can target specific regions of the image for modification. This provides more precise control over the final output and allows for detailed adjustments based on your preferences.
Upscaling Images with Image-to-Image
Image-to-image is also useful for upscaling low-resolution images to higher resolutions. By inputting a low-resolution image and adjusting the settings, such as using the resize option to scale up the image, you can generate a higher-resolution version while preserving the essential details from the original image. This can be particularly helpful when standard upscaling methods do not yield satisfactory results.
