Hi there, I’ve been toying around with Stable Diffusion for some time now and I’m starting to get a bit of a feel for it. So far, I’m quite happy with my workflow for generating image compositions (i.e. getting the characters, items, poses, … that I want). But these images look quite crude sometimes. Question is - what tools can I use to iron out images, get them more crisp looking and so on, while keeping the image composition the same all the time? Any tips are highly welcome

    Civitai has a bunch of Lora’s that might help with crispness? My favourites are Denoise & AddDetail. I’d also use a popular SD1.5 model like Deliberate (until sdxl is released). I always do highres fix, maybe scale 2x from 512 on a low denoise & see what you think.

    There’s also an after detailer extension I use for doing extra processing passes on hands/face etc.

    Honestly I go through a process where I place the image into img to img and re-render the image at increasingly lower and lower denoising scales until I get a result that looks good. I tend to alternate between sampling models too, depending on what I’m going for. Haven’t quite got the hang of inpainting yet, but I’ve seen other people’s workflows of upscaling the image and then address problem areas individually.

      Yeah it’s really kind of a process right now. Most of the time I can get an okay image with a really good prompt, but if I want a great image it’s usually

      • Form the perfect prompt, couple hours fine tuning
      • Move to img2img, render to make a bit more cohesive
      • Pick one from the batch, use in paint
      • For each round of in painting:
        • Paint area
        • Alter prompt
        • Make a batch that’s nice
        • If good, move to next round of in painting, else repeat
      • A couple final rounds of img2img
      • Scale up

      It’s quite a process right now to make it perfect. Overall if you want something real specific it may take a few hours of fine tuning and adjustments to get it there

    You mean the step after the ludicrous amount of inpainting one has to do sometimes?

    Apart from the mentioned adddetail lora (works in negative prompt as well), maybe rerunning the image through ultimate sd upscaler with the controlnet extension? (go easy on the denoise level here, or your image becomes a surrealist’s dream)
