I am sure this http://theonlinephotographer.typepad.co ... n-ep1.html is easy to do in PWP.
Has anyone tried it?
Presumably it could also be built into a workflow?

Re: RAW + JPG = Less Noise ?
Ctein's recipe is: "Start with the JPEG as the base layer, convert the RAW to a grayscale image ..., paste it in as a second layer over the JPEG, and set the blend mode to Luminosity."
Roughly, wouldn't the PWP procedure be:
Roughly, wouldn't the PWP procedure be:
- Open raw file and go through the Raw dialog
Convert result to grayscale: Extract the HSV-V or HSL-L channel
Open the JPG
Extract its H, S, and V channels, or its H, S, and L channels
Composite | Blend the JPG V or L channel with the grayscaled raw
Gray | Combine Channels: the result with JPG H and S in place of the JPG V or L

Re: RAW + JPG = Less Noise ?
As I occasionally for 'highly detailed' tone-mapping will Stack Images, Composite-Blend, and 1:1 Clone; Canon DPP and PWP RAW conversion image versions and their Extract-ed channels, there are two things specific to my Canon EOS-350D camera image files that may apply for your camera files and software settings as well...
...when performing the V or L channel RAW->JPEG substitution suggested by Charles2's "PWP procedure":...
(1) the PWP RAW conversion image does not have '1:1 Registration' with DPP conversion or camera JPEG images.
For a Canon EOS-350D camera, the Canon DPP RAW conversion image and the camera JPEG [highest resolution] image will have the manufacturer's specified 3456 x 2304 pixel dimensions... ...and the PWP RAW conversion image will have 3474 x 2314 pixel dimensions. An asymmetrical margin crop of: left 8, right 10, top 5, and bottom 5; is required for '1:1 Registration' of PWP's RAW conversion file with the DPP/camera JPEG files.
(2) To Combine Extract-ed channels, the channels must have the same bit depth [8 or 16] so a Convert of the Extract-ed channels to the same bit depth may be needed before the Combine step of the procedure [PWP will advise with a warning if the bit depths differ] as generally Extract-ed RAW conversion channels will be 16-bit and the JPEG Extract-ed channels will be 8-bit.
