I had done it partially before so I knew it would work well with this image, but I finished it in high res just for you.

The first step is to dial in the prompt and settings. I test different models and denoising strengths to see what looks good. Sometimes it has trouble understanding a pose until you give it the right prompt. In this case it understood it fairly well, but specifying hands_on_hips, short_sleeves, and pencil_skirt helped.

Once it starts looking good, I generate a bunch of images with the those settings. Then I piece together the good ones in photoshop and do a little retouching. It's rare for one image to have good everything so I'll take the face from one, the body from another, etc. The hands are usually messed up and have to have parts redrawn.

Then I export the composite image and upscale it 3x. Then I'll do AI inpainting on key parts to high-res-ify them. In this case, her face, her boobs, and her waist. I tried her skirt a couple times but I ended up keeping the original.

The main thing for this one is that I knew it would work since I had already done the prompt testing part at low resolution on my old video card. In general a simple pinup pose like this is easy since there is lots of training data for it. I have yet to get good results on unusual angles like this https://satinminions.com/Suction-Dildo-Shower-04.html or first person shots.

It is possible to just run an image through and get pretty good results. But if you want a high res output where you struggle to find flaws, more work is required. Here is the raw output for this image: https://satinminions.com/SD-15675-Raw.html

Writing all that makes it seem like some huge process. It's way easier than drawing something. But a breakdown of the drawing process is like:

Draw some lines. Color 'em in.

The main bottleneck for AI is the time it takes to generate images. If my computer was infinitely fast, it would only take minutes. As it is now I usually queue up a batch to run when I'm afk, which isn't often.
