Introduction

In this chapter of the Free and Definitive Stable Diffusion Course, we will explore how to make modifications to an image using the Instruct Pix2Pix tool. Whether you want to turn a person into a blonde, add a mustache or a beard, or completely transform an image into a Van Gogh painting or an old Polaroid, you can achieve it with just a single line of text. In this article, we will guide you through the process of downloading and installing the necessary model and demonstrate how to use the Instruct Pix2Pix tool to create stunning image modifications.

Downloading the Model

Before we begin, you'll need to download the Instruct Pix2Pix model. You can access the model from the Hugging Face website, which we will link in the description below. It is recommended to download the SafeTensor version of the model whenever possible. However, keep in mind that the model file size is approximately 7.7 gigabytes, so you will need a graphics card with at least 10 gigabytes of VRam. If you don't have enough memory or don't want to compromise your free drive storage, you can use the online version of Instruct Pix2Pix, which runs directly from the Hugging Face website without any cost. We have provided the link in the description for your convenience.

Installing the Instruct Pix2Pix Extension

Once you have downloaded the model, you will need to place it in the specific folder for general models. To use the Instruct Pix2Pix tool, you must first install the corresponding extension. Here's how you can do it:

1. Click on the "Extension" tab.
2. Select "Install from URL".
3. Paste the URL of the extension, which we have provided in the description.
4. Click on the "Install" button and wait for a few seconds.
5. Go to the "Installed" tab.
6. Click on "Check for updates" and then "Apply and Restart UI".

After completing these steps, you will see a new tab called "Instruct Pix2Pix" in your interface.

Using the Instruct Pix2Pix Tool

Now that you have successfully installed the Instruct Pix2Pix extension and have the model ready, you can start using the tool. Here's a step-by-step guide:

1. Firstly, load the image you want to modify by clicking on the center of the screen and selecting the desired image.
2. For this example, we will only modify the image using a Prompt. We won't use any masks or modify specific areas.
3. Let's start with a simple modification. Type the prompt "Change the hair to blonde" in English, as shown on the screen.
4. Click on the "Generate" button and marvel at the perfectly transformed image.
5. Let's try something different. This time, let's add a mustache to the person's face. Type the prompt "Put a mustache on her face."
6. Once again, click on the "Generate" button, and behold, a lovely mustache appears on the face of the charming lady.
7. Now, let's try adding a tattoo to the person's arm. Type the prompt "Add a tattoo on her arm."
8. The tool does a fantastic job of adding a tattoo to the arm.
9. We can be even more specific by instructing the tool to add a specific tattoo, such as a star. Type the prompt "Add a star tattoo on her arm."
10. If the result is not satisfactory or doesn't meet your expectations, you can simply generate another image. In most cases, the new generated image will be much better.
11. Let's switch to a different example. Load an image of a bowl filled with apples.
12. Now, let's ask the tool to replace the apples with oranges. Type the prompt "Replace the apples with oranges."
13. Voila! The image now showcases a bowl full of oranges.
14. If you're not satisfied with the result, you can always change the prompt and try a different approach.
15. Let's try changing the apples to bananas this time.
16. The tool does a remarkable job, especially considering that it doesn't modify any other part of the image.
17. In addition to the main modifications, there are two adjustment parameters available in the tool.
18. The first parameter, "Text CFG," allows you to amplify or diminish the power of your prompt. The default value is 7.5, which is a good starting point for your experiments. To increase or decrease the effect, you can adjust this value accordingly.
19. Let's see an example. Load an image of a road with trees, grass, and a bench.
20. Type the prompt "What if it had snowed?" in the prompt box.
21. The resulting image shows a thin layer of snow, suggesting a light snowfall.
22. Now, let's intensify this effect by increasing the "Text CFG" value. In this example, we'll try 17.35.
23. The newly generated image reveals a road completely covered in snow, including a touch of snow on the bench.
24. We can further amplify the effect by increasing the "Text CFG" value to 22.
25. As expected, the effect becomes even more pronounced.
26. On the other HAND, the "Image CFG" parameter allows you to amplify or minimize the effect by increasing or decreasing the value. Unlike "Text CFG," this parameter can affect the consistency and unwanted modifications of the base image. Exercise caution when adjusting this parameter, and make slight adjustments if necessary.
27. There are several additional options available, such as the number of samples in each batch generation and different sampling methods. You can experiment with these options to achieve the desired results.
28. Furthermore, you can fix or randomize the seed for a more consistent or varied outcome.
29. If you prefer a truly random configuration, you can use the "Randomize CFG" option to set random values for both "Text CFG" and "Image CFG."
30. Keep in mind that the final generated image will have the width specified in the respective input box. However, note that altering the width may make the image more difficult to modify, requiring adjustments to intensify the effects.
31. Finally, this concludes our chapter on using the Instruct Pix2Pix tool. In the next chapter, we will explore even more powerful tools. Don't miss out, so make sure to subscribe and give this video a like if you enjoyed it. Thank you for watching, and we'll see you in the next chapter!
