Focus methods


Recommended Posts

I don't know of an unsharp mask plugin (like in Photoshop) for Resolve;  too bad.

Short of that, you might try splitting out the luma from the chroma and manipulating those independently, but truly out of focus material is really hard to recover.

Josh Petok shared a tip from Mike Seymore's Red302 class at FXPHD:

 



When sharpening images, sometimes you'll notice a color fringing around the edges. This image has sharpening set to 20.

Here's the same image zoomed in 200%. Notice the fringing around the edges.

In Resolve, by default, the sharpening algorithm is performed on both the luminance and chrominance of the image. Ideally, images could have cleaner sharpening if it was applied only to the luminance of the image. Here's how you do it:

Start by creating a Layer Node

In the first node, lower the saturation to 0. This will remove all the color information from this node.

In the second node, lower the luma gain to .01 (the lowest that it will go)

All that is left in this node is color information.

In the Layer Node, change the Composite Mode to "Add"

If you enable/disable all our nodes at this point, your image should look exactly the same as it did before. All we did was separate the color from the luminance.

Now that your color and luminance are discreet elements, add a serial node after your luminance only node.

Apply a healthy amount of sharpening

Notice that the color fringing is gone from the edges
