First of all I do not claim to be an authority on the subject. If I was writing something academic it would not be on a web forum.
Second you are talking about illusion which is USM halos. This thread is about deconvolution programs. You always seem to come out talking about PS or lightroom. In the sharpened images I posted there are fairly harsh jumps in luminance from deconvolution. Jumps that create an aliased look. You are looking for the ruts on the sides of edges created by USM.
Third it is intended as SRGB with Gamma 2.2. That is how I output from RT. Images Plus that I used does not know about color gamuts. It will display colors with an unknown approximation based on sRGB. The math that it does is precise. If another app opens the jpg it will be based on the original RT output color apart from one thing. Part of the normal sharpening process I use in the program is a routine called adaptive contrast. It increase saturation as well as luminance contrast. That is why I stated the program is not color controlled. You can consider that saturation +5 (approximately) from the RT output.
If you have a version that you feel looks better, post it.
Which 2.2 gamma? sRGB 2.1 Microsoft, HP and Apple came up with that has the non-standard gamma curve? Or the 2.2 gamma curve that's in AdobeRGB? That's all I'm talking about. I didn't raise the question about color.
You'll have to excuse me for not correlating and seeing the benefit of all you outlined above concerning deconvolution from RT just from examining your posted sample. I didn't even know that that was what you were trying to communicate even though you sounded so sure that you were giving helpful information that could be used by contributors to this thread including Erik. I was trying to gleem and understand the benefits from your initial response until I noticed I was working on an untagged image. You didn't come across as academic in what you were trying to explain.
There's only one thing I'm concerned about with regards to sharpening and that is to get the best edge detail applied evenly across the entire image without artifacts. IOW achieving a natural look to a sharpened image. I'm not interested in micro sparkles showing up in order to get this. LR's PV2012 changed their Masking slider behavior that handles those types of artifacts quite well at least way much better than previous process versions.
I also notice in discussion of this kind that I find most folks don't know how to explore and use the tools they have to get the best results and start to blame the software instead of understanding how to create an illusion that is a sharpened image and that requires an intimate knowledge of what the tools are doing to the image on pixel level. Erik gave the perfect demonstration of this. I don't care what tools a photographer has to create the best looking image. I care more about them learning how to use those tools.
I know what a well sharpened image is suppose to look like down to the pixel viewing level because I know what that will look like when downsampled/upsampled for viewing on display and prints at the right distances and resolution and that's all that matters.
