- Force the brightest pixels to be white, the darkest pixels to be black and spread out the ones in between quadratically such that pixels with a brightness of `n` become 50 % bright:
`pnmnorm -midvalue {{n}} {{path/to/image.pnm}} > {{path/to/output.pnm}}`
`pnmnorm {{[-midv|-midvalue]}} {{n}} {{path/to/image.pnm}} > {{path/to/output.pnm}}`
- Keep the pixels' hue, only modify the brightness:
`pnmnorm -keephues {{path/to/image.pnm}} > {{path/to/output.pnm}}`
`pnmnorm {{[-k|-keephues]}} {{path/to/image.pnm}} > {{path/to/output.pnm}}`
