After enabling Denoising Data pass, there are now two image outputs:
- Image
- Noisy Image
Which should I use with the Denoise node? Blender Manual doesn't cover it.

When in doubt, use the Image pass.
Image
- provides unmodified render result
- output also comes denoised by the Internal denoiser if it's enabled
Noisy Image
- provides a Despeckled image (useful when render has fireflies)
- may cause bad shadow artifacts for low sample counts
