Now that I've discovered Neat Image, I've put it right at the start of my workflow, and then bring the Neat-Imaged pic into PS for the rest of the processing.

My question is; is it better to leave the sharpening until the end of the workflow, and just use Neat-image for noise removal? - I've tried the 'sharpen' option in Neat Image, but I'm not sure if the PS Unsharp Mask gives better results.

I have always waited until last for neat image if I choose to use it. I believe it is just personal preference.

The reason I do NeatImage first is that I got this idea in my head that NeatImage reduces the tonal range slightly (these large areas of sky that previously had multiple 'noise' tones now have less)

So I wanted to place it before the crop and levels steps.

I'm getting obsessive, I know... Why does my brain have to work in such an analytical way?! :-)

I think it's best to use any noise removal routines as one of the first steps in processing, particularly before any type of USM is applied. Sharpening changes the actual "signature" of the noise that NEAT and other programs are trained to recognize and remove. Therefore, if you NEAT after you have already sharpened, you have decreased NEAT's ability to remove noise.

Second what strangeghost says. Wherever possible, use neat image at the very beginning to establish the canvas on which you're going to work. The only exception is that some sorts of agressive post-processing actually introduce/create noise, so you may have to do noise removal, at least on some areas of the image, afterwards. It's better, of course, not to get that "pushy" with the PP... Definitely save the sharpening for later I'd say...
