The prompts are the same cus images are generated in txt2img with Hires. 3, 512*512, CFG scale 7 to 8 and 80 steps for Euler a. 5 de-noising strength. To understand the new highres fix we have to explain a couple terms: Firstpass = simply an image generated without highres fix enabled. First Hires Fix with Latent(bicubic antialiased) at 0. 12 and 4x-UltraSharp to get to final resolution. But if I try to upscale in img2img using either SD upscale or Ultimate SD upscale, either I have to set the denoising strength too low and no additional detail/sharpening is added, or if I set it too high some detail is added but now the gorilla's nipples turn into eyeballs and his fingers If it is the hi-res fix option, the second image subject repetition is definitely caused by a too high "Denoising strength" option. Then click on option "just resize latent upscale". fix with the settings descripted in this Post. fix』の使用方法について解説しています。Upscaler やDenoising strengthの設定値の違いや使用するメモリについても解説しています。 /r/StableDiffusion is back open after the protest of Reddit killing open API access, which will bankrupt app developers, hamper moderation, and exclude blind users from the site. 5x with highres fix, then 3x or 2x with upscale but there's no limit but i find hard to work images above 3000x4000 Reply reply How is taking the image out of latent space by not using Highres fix in txt2img and then sending it to img2img to generate at the same 2x resolution less demanding on the graphics card? I guess that it's more memory efficient to dump the information into a png between the 2 steps, but in the end the card needs to infer at the same 2x resolution I use Absolutereality too. Photogenic Batch size: 4, Batch pos: 1, Denoising strength: 0. Part of my workflow involves highres fixing at varing denoise strengths (generally 0. There are two different ways to upscale an image with 1111 and honestly I'm not sure if the highres fix is worth the extra time. Aug 6, 2023 · I think any visible difference in face itself is due to denoising strength. I know there's various tile upscaling workarounds but they don't use the initial latent rendering space like hires fix does which is why I'd like to get it to 4k with a direct render/upscale if it's at all possible. 5 denoise works very nice. 4 to 0. Low denoising strength should result in images more similar to the exploratory smaller-resolution image. 2). but a lower denoising strength leads I made a detailed video about hires fix. but your pc needs to a beast to handle this. Oct 5, 2023 · Stable Diffusionで生成した画像を高解像度にアップスケールする『Hires. Denoising determines how much it mixes between the first and second. Denoising strength: 0. 2 and see if the problem persist (normally any other than Euler A will display this artifacts) Hi-res fix version looks like ass and ruins the face. 0 upscaler using x4-upscaler-ema. I tried using Hires. in the prompt. 3 in terms of pixel quality. Try lo lower it, starting from 0. 3) Are you using highres fix? By default, the denoising strength is set high, so that tends to "wash" the entire palette into the dominant color. It is observed that at low denoising strength of 0. 5, sometimes 2. The latent upscalers add additional detail, but it's a gamble because denoising strengths that high will produce significant changes in your original image. 1 denoising, and change tile size to 768 if the picture starts to fall apart. A regular generation. Fractalization/twinning happened at lower denoising as upscaling increased Latent upscaler = any upscaler with "latent" in the name Non-latent upscaler = any upscaler without "latent" in the name I just started using stable diffusion so my knowledge is limited. Experiment to find a denoise strength that adds fine details while respecting your original image. 2) the prompt won't have much influence but if you turn up denoising you can also alter the image a lot during the upscale. fix, and WoW what a difference. 25 and 4x-UltraSharp (put this in models/ESRGAN) to double again. You dont select an upscaler by Hires fix with the latent space upscalers is different than img2img, as they upscale the image before it's converted to pixel space. 6? What's your workflow for upscaling besides the Hi-Rez fix? Hi OP I've just literally posted something identical! I also have an 8GB card (3060ti) and would like to hires fix directly to 4k. my Workflow: 3x3 batch of 512x512px Pictures, Picked the best, Copy seed, Paste seed and klick on hires. However with hi res fix on, it takes me about an hour or even more just to generate one image. Used SD upscale script for first 2 images, upscaled initial outputs with topaz gigapixel (standard model) then ran SD upscale with none upscaler selected, for 150 steps at 0. This is why I wanted to ask what other people think. If Highres-Fix changes up the image too much, use the SD-Upscale script in the img2img tab with a denoising strength of < 0. Seems like the captions were cut short. I just got stable diffusion yesterday messed a bit around with it and downloaded some models. 1-0. 45 denoising is indeed better than 0. Most of the time a "noisy" upscaler will give nice final details with denoising above 0. 1x and 0. More new detail is added. Alternatively, you could Img2Img with a very high denoising strength (92+) and a good CFG Scale (12+) a very large picture with only one character. So the denoising will allow your prompt to do its job without the starting pic defining the pic too much, but will still follow the same composition. 5 (No Scale latent) Embedding: Asanagi Well, i used this collab to generate the AI image generator UI and for higher quality photos i set the resolution to something like 1024×1620(doesnt have to be exactly that, but higher numbers mean better quality) and then I use the highres fix option that the UI provides and set the denoising strength to 0. The list of artists isn't mine; it's been circulating for a while. 35x to 2x, and a Denoise of 0. They will very lightly guide the design into a specific fashion niche. Found a pretty good way to get good pics without highres fix : you generate normal 512 img, send it to img2img. Image 1 - 1028x1028, 10 steps - Here Prompt S/R replaced 1. I want to see the initial 512x512 image, and then decide to make a high-res version. Latent(bicubic antialiased) can handle 0. 50 and above) more Hi-Res steps have a much bigger effect. 5 denoising. 38 seems more optimal. In the image generation module, you'd select HiRes.
