Stable Diffusion - Negative Prompts in Fooocus - Do they make a difference?

Ғылым және технология

Master Fooocus and Stable Diffusion for Creative Image Generation! 🎨 In this Stable Diffusion video I go over negative prompts in Fooocus and if they have an impact or not. Those really long negative prompts may be doing nothing. #Fooocus #StableDiffusion #DigitalArt #ImageManipulation #CreativeTools
This is part of my ongoing series of videos on installing and using Fooocus for Stable Diffusion. Fooocus is a great interface for using Stable Diffusion and is very easy to get started. It also will run on systems with only 4GB VRAM.

    Oh then you may want another tip... "default_max_image_number": 1000 can be added to your config.txt file so you can have even more. lol. I actually use 100 as my default but have used 1000 in the past. I am not at the computer to paste the link to the video but I do have one on customizing if you are not familiar with modifying that file.

    Great tutorial! I was able to do this by describing everything but the rain and it came out great with the following prompt. - wet woman walking on a city street with wet hair and clothes on a dark cloudy day

    I tried to replicate your results and got exactly the same - couldn’t get rid of the umbrella. However if I changed the prompt to ‘a woman walking in the rain with her hands in her pockets” the umbrella disappeared. I guess it comes down to reforming the prompt to counteract the item you want to get rid of.

    Yup. Always better to use the regular prompt to get results rather than depend on the negative. Funny thing is even when I had her do things like carry other stuff in her hands there would often be an umbrellla just floating. Also found that the closer to the camera the less likely for one. Further away you are more likely. Have her dancing in the rain instead of walking and no umbrella.

    Will the negative prompt work with a random seed? How about using the prompt "Woman getting wet walking in the rain"?

  • @KLEEBZTECH

    @KLEEBZTECH

    4 ай бұрын

    Did over 100 random ones. And yes usually the best approach is to try to use the regular prompt to get what you want. I was looking for examples to show that the negative prompt is not usually the best way to go and you want to use the regular prompt preferably. Just like with a house on a hill it would be best to mention an empty field instead of using negative prompt to not have trees.

    Thx for all these intresting videos for Fooocus, really appreciate them and gets me thinking! As you hinting at around 8 min mark, to put more into the positive prompt. I would say at times, for the positive prompt, try for example to describe, lets say the reality that happens in your wanted image. (Maybe also works for the negative prompt...) For your first example. add a description of wet hair, and the umbrella never gets created for the woman!, but can at times be visible on other people in the image. a woman walking in the rain, wet long black hair So thinking how to describe something, so the unwanted thing have no logic reason to be created in the first place! If the umbrella is created, there can't be wet hair :), ofcourse in AI anything is possible and sure happens :) It really is a fun challenge!

    ah ok the wonderful world of AI It's so odd, that different ppl with same type of workflow gets the outcome so different. I just did maybe all in all 50 fast tests directly when I saw your video, and I didn't get a single umbrella, not even a hint of one near the woman :) I got just a couple on other ppl if the there were other ppl in the image. But then I added, people with wet hair in the background on a city street, and umbrellas were gone :) But hey, the developement of AI is so extremely fast, I don't think I have seen another field in many decades that have this, I am sure it will only accelerate even further as time goes :) "what a time to be alive" :)

    I went and tried your exact phrase and did get less umbrellas although ended up with much more zoomed in shots. I had phrased it a little different. Once I try to force it back to wide angle then the umbrellas start coming back. But it does come back to the idea of getting what you want with the regular prompt instead of trying to use the negative. Just have to be creative.

    Another good way to compare is to put the images to compare in the same folder with nothing else and you can flip between them to notice any very subtle changes. That is useful when the changes are very slight.

    So to summarize, while in some cases short negatives might have an impact with some models and some seeds, for the most part the answer is "usually no"?

    Do you unselect Foocus styles by default (V2, Enhance) for the tests ? If not, you don't know what text is exactly in your final prompt. And by the way, there are some negative embeddings available on Civitai.

  • @KLEEBZTECH

    @KLEEBZTECH

    4 ай бұрын

    The best way to test if they're being ignored completely is to turn off random seed. Then generate an image with nothing in the negative prompt and then do it again with the negative prompt filled in. If they look the same double check that they actually are by opening up one of the images in the photo app or something and flipping back and forth between the two. Even if slight differences you will notice the shift in pixels.

    Then try different things and only have one thing in the negative prompt when testing. And apply extra weight to it. Something that will affect the size I find is often a good thing to test. Sometimes you have to rework your prompt so it doesn't need to rely on the negative.
