Diffusion Node Trees - for Davinci Resolve

Fully customizable diffusion node trees in a linear space to emulate glow and softness.

Includes a detailed PDF explaining each node tree and which parameters to modify

Diffusion 1

This version contains a full stack of Gaussian blurs on a linear transfer function.

Diffusion 2a

This version contains the same stack of blur nodes, this time using a key input for each node.

This key input uses curves, so it's fully customizable for you to dial in what areas of the luminance scale you want to target.

Diffusion 2b

This version uses a luminance qualifier as the key input for the blur stack. Use the softness and low parameters to target different areas of luminance.

Diffusion 3

This version has an initial diffusion node taking the "edge" off the whole image for a more organic look, followed by a stronger of softening targeting the edges of the frame similar to a vintage lens. You can adjust the size of the mask or the softness to extend the blur from the edges towards

Diffusion 4

This version is doing an MTF adjustment, targeting areas of high frequency detail using a high-pass filter. In the MTF node’s blur parameters, dial in the amount of softening you want.
