# multi sample pixel space sharpening
I think this is a good name for it. Not sure.
Takes an image from text prompt and
* samples it
* uses a model to upscale
* resamples it
* repeats
* at the end, uses uses a 4x upscale model to increase the size again
* saves it at a total of x8 size
Basically a series of hi-res fixes then an model upscale
Moving noodles switches between model vae and vae loader.
## Example
## Variations
* [with latent upscaling.](../multi-sample-sharpening/)
* [Using the standard image upscale nodes](./multi-sample-pixel-space-sharpening-b.json)
* [a fast one with smaller images sizes](./multi-sample-pixel-space-sharpening-c.json) to "check it out" sort of thing.
* [adjusted image sizes, added img2img nodes, cleaned up some lines and nodes](./multi-sample-pixel-space-sharpening-d.json)
* [save filename prefix nodes](./multi-sample-pixel-space-sharpening-e.json)
* [using tiled ksamplers and tiled vae](./multi-sample-pixel-space-sharpening-tiled.json)
* requires blenderneko's [tiled ksampler](https://github.com/BlenderNeko/ComfyUI_TiledKSampler)
* also includes the newest version of custom folder/prefix substitution
