Hi CH, nice to "hear" from you!

Thanks for the warm welcome, Mike and Piers. I'm still reading the list everyday and wait to see if I can contribute
something :-) Topaz Sharpen AI is one of the topic as I found it very useful for saving the shake shots. Thanks for
Moose image samples on the Sharpen AI, it led me to purchase the software.
After playing the software for a few weeks, I found it very good for shake and noise reduction but you have to be very
careful on the artifacts it could create during the process especially in "Motion Blur" mode. The software has problem
in many areas but it worth the money even it only works on certain percentage of the problem images I have, it is
highly recommended.
With four primary models, "Very Noisy" and "Very Blurry" submodes and 3-4 settings within them, the options are sort of
endless. I never use the "Auto" setting.
I'm not sure I've ever found an image where Sharpen doesn't made at least a small improvement in one mode/setting or
other. In other cases, the results have been magic.

I tried DeNoise AI two years ago, wasn't very happy with the result since it removed some fine details together with
the noise (with digital image), don't know if the updated version will do better.
You are WAY behind. Denoise AI has changed and improved a great deal since then. The interface is now like Sharpen, with
four windows, which makes choosing mode/settings MUCH easier, and a new Low Light Mode. It also has the faster engine.
I think this will show that your application of Raw Therapee is far behind Topaz.

Notice that most of the "sharpening" happens in Denoise, with Sharpen making a small improvement. This isn't the case
with every image, of course, but pretty common. I use Denoise AI on almost every image, and Sharpen AI on some. For base
ISO files, Denoise 21 1 15 0 usually cleans detail up beautifully, even if the subtle NR doesn't matter.
For film images I used to use Neat Image to remove the grain.
NeatImage was my choice for years. Except for very rare situations, I no longer use it. For example, If I'm using a mask
and want to completely remove noise and mottling in areas(s) with no detail, it's useful.
Here's an old example where I compared two settings of NeatImage to an NR you posted. I've added Topaz Denoise AI and
Sharpen AI versions. <http://www.moosemystic.net/Gallery/tech/Process/NR/E3_1600_NR.htm>
Without the Raw original, I can't compare DxO Photolab 4's Raw NR, but I'm confident it would be much better than
RawTherapee, and almost certainly not as good as Denoise AI.
BTW, I still use FocusMagic to alleviate sampling softening after downsampling for the web. Used on its own layer(s),
often masked, and using layer opacity to adjust intensity, I like it better than Sharpen AI for this particular use.
