Ceci est une ancienne révision du document !
This month, as noted last time, we will take a look at Fooocus. The Fooocus interface is simplicity itself as shown. Only an image window and prompt space is immediately obvious, and your gut feeling is likely unimpressive, it’s almost childlike. But typing in a few Prompt words: tiger in snowy mountain country, and selecting the Generate key, is almost amazing. Without any further input, Fooocus creates a stunning image, two by default. The secret is that it expands the input prompt used adding what it “thinks” might work.
Thus if you look at the actual prompt used, not the one you input, you will find a significantly larger prompt: tiger in snowing mountain country, cinematic, full focus, highly detailed, still, background dramatic, intricate, elegant, luxury, artistic, sharp focused, beautiful, passionate, color rich, inspiring, attractive, professional, thoughtful, cute, best, creative, charming, peaceful, pretty, enchanted, cool, friendly, famous, majestic, magical, colorful, breathtaking, and also any negative prompts when used.
You can do this using a wonderful feature called History Log. You can access this by checking the Advanced checkbox on the bottom of the page, and then clicking on the History Log feature with the Setting tab selected (see below). This opens an HTML file of your most recent session. It is saved by default in the Home>Fooocus>outputs folder as a folder named for the date of creation. It will contain each generated image, along with the log.html file (the History Log) which, when opened, shows all the data and pictures created. The History Log feature should make it much easier to recreate images because all the important parameters are listed. Or you can try using the same inputs and parameters via a different interface like ComfyUI or Easy Diffusion.
Its simplicity makes it so useful, especially for the newbie. Let’s say you need an image “Serendipitous Synchronicity” for some purpose. No muss, no fuss, just input the two words and see what you get. One output is the view of sunflowers facing you and not the sun. You can add the needed text via Inkscape and you are done. Note that not every simple Prompt text will create a terrific image, and even creating 20 images is not a guarantee of success.
The created input text is: serendipitous synchronicity, rich vivid colors, ambient light, dynamic dramatic cinematic magical atmosphere, precise perfect, focus,, very inspirational, innocent, trustworthy, elegant, intricate, highly detailed, generous, color, fine detail, clear, aesthetic, cool, cute, pretty, friendly, artistic, professional, decorated, deep royal, elite, glowing, noble.
While text creation using the prompt is getting better, it’s not dependable, so avoid the extra work and add it yourself. The program created text is not editable in the produced image so even slight modifications would require regeneration. That additional complexity would likely increase the model size and ultimately hardware requirements. But we are still in a steep growth phase with Artificial Intelligence image creation software.
After creating a few images, you probably want more options, perhaps not to the level of ComfyUI, and Fooocus does not disappoint. When you select the Advanced checkbox, a variety of the expected options become available. Under the Setting tab, various performance and image options are now available. Selecting the Style tab offers several hundred styles, and when your cursor is moved over a style, a small cat image pops up to show how it will modify your image. The search option at the top helps find the desired style. Selecting one will move it to the top, and un-checking it will remove it from image generation. The third tab Model gives you options for the models used. This is dependent on which models were downloaded and whether you restarted Fooocus after adding the model. And finally the Advanced tab allows you to adjust the Guidance Scale and Image sharpness via sliders.
Next time I will address installation and use of some other options.
