Stable Diffusion IMG2IMG: EVERYTHING you need to know IN ONE PLACE!
Science & Technology
Introduction
In today's article, we will explore the powerful image-to-image (IMG2IMG) tool in Automatic 1111, discussing how to create stunning new images or modify existing ones. From using existing photos to in-painting and sketching, this guide covers it all. Let's dive into the details of the IMG2IMG tab and its multiple functionalities.
Understanding the Image to Image Tool
The image-to-image (IMG2IMG) tab is an essential part of your AI art toolkit. This tool allows you to create new images or elements from an existing picture that you provide. The process starts with an image that you serve as a starting point, and you can draw upon the composition and color elements to generate a brand-new image.
Getting Started with Image Uploads
To demonstrate the capabilities of the IMG2IMG tool, we'll use a previously generated portrait of a girl on a city street, made using the SDXL base model. However, you can utilize any image you prefer — whether it’s a photo, a painting, or another type of artwork.
To start, drop your chosen image into the image-to-image box. You can also use images sent over from the text-to-image tab by clicking on "Send to image to image" under your generation.
Settings Overview
Below the image box, you'll find various settings that can enhance your workflow. While some of these settings are shared with the text-to-image tab, there are specific settings specifically for IMG2IMG.
Resize Mode: This affects how your original image is adjusted to fit the new canvas size.
- Just Resize: Stretches or shrinks the original image.
- Crop and Resize: Maintains the aspect ratio, cropping the image as needed.
- Resize and Fill: Fits the original image and fills any extra space with colors from the original.
- Just Resize (Latent Upscale): Similar to Just Resize but also upscales the image, though this setting may be tricky to balance.
Denoising Strength: This crucial setting controls how similar the new image will be to the original one. A lower value means less change (e.g., 0.5) while a higher value (e.g., 0.7) results in a more significant change.
After you've adjusted your settings, you can start refining your image by tweaking prompts or denoising strengths to achieve the desired effect.
In-Painting: Making Specific Changes
To make specific alterations without affecting the overall composition, utilize the In-Painting tool. This tool allows you to paint over parts of the image you want to change, enhancing targeted elements while keeping the rest intact.
- Adjusting Settings in In-Paint:
- Brush Size: Change the size of the painting tool.
- Mask Blur: Controls the blurring around the painted mask.
- Mask Mode: Choose between altering only painted areas or everything except painted areas.
You can also select from several masked content options to influence how the new image is generated based on your painted mask.
Adding to Your Image with In-Paint Sketch
After modifying the initial image, you can utilize the In-Paint Sketch feature to introduce new elements, such as clothing or accessories. Simply paint over the area where you want to add something new and input your prompts to describe the desired feature. This method is particularly effective when you want to add specific items while retaining the integrity of the original art.
Advanced In-Painting with Uploads
For those looking for even greater control, In-Paint Upload allows you to create a detailed mask in an external program like Photoshop. By using black for the areas you want to keep and white for those you want to change, this gives you precise control over the editing process.
Sketching Ideas
If you're struggling to visualize your ideas, the sketch tab allows you to flex your creative muscles. You can drop in a black or white canvas to start sketching out concepts visually. Use colors to enhance details and pair your sketches with prompts to transform them into full-fledged images.
Conclusion
The image-to-image tool of Automatic 1111 is a versatile and powerful asset for any digital artist. From minor tweaks to full-scale transformations, the possibilities are endless when harnessing this tool.
