This repo currently has two sets of nodes - one set for editing the contrast/color of images and another set for saving images as 16 bit PNG files.
I'd recommend using it with `--fp32-vae` to get the full precision output. BF16 definitely doesn't have enough precision, FP16 might work but will NaN randomly on some VAEs.

- The FP16 VAE seems to be similar to the synthetic one, maybe due to the lack of precision?
- The BF16 VAE apparently only has 7 bits of precision for the mantissa, so it's a pretty bad format to store the [0-1] VAE output in.

*Or I might just be graphing weird float rounding errors. Who knows.*
