So far, I'm enjoying Silkypix very much: thanks Carl!
I've only gone through two complete editing sessions (start-to-finish) to see what I can do, and I was quite pleased. Unfortunately, I used rather ugly photos, because I wanted to pick images that had never been improved or worked on previously, so that I wouldn't be tempted to 'recreate' something I had done in other RAW apps, which I didn't see as completely fair. I say this because part of one's choices may incorporate what you 'know you can do' with a certain set of applications, and this app seems to bring some very different ways of doing things, and even some new capabilities altogether.
Next, now that I know a little bit better how Silkypix works, I will try to recreate some images I have worked on before, and then compare the output. Then I will have some pudding for final proof.
In general, I wish they could 'tone-down' the gratuitous use of sliders: yes, they make it easy, but it forces many controls to be 1-dimensional in usage, and often the corollary to an adjustment isn't included in the same dialog box. That means a bit of efficiency goofyness hunting for a related slider, but I have found that there's almost always a corresponding control somewhere .
The use of presets that can be called up globally or locally right down to the dialog box is excellent, and its so quick & easy to switch or add a new setting.
Dual previews, the 'Corel/Kitchen Sink' approach (include nearly every functionality you can imagine - like lens shift, aberration controls, curve/histogram tweaks, colour tweaks down to a sub-palette, clone fixing, dynamic setting previews, and so on, and so on...), smart batching, all let you do 98% of your work in just one application. It has truly optimized processing performance whether using a single-core very fast (3.6GHz) cpu, or slower multi-core processors.
I have only seen sRGB and Adobe RGB (no ProPhoto), but that's all I can do with my camera anyway.
I really like the unbelievably precise, yet intuitive colour controls, even more than Capture One (which says a lot). I think these are the most nuanced and powerful colour controls I have ever used.
The sharpness controls are OK, maybe not quite as controllable as LR, but I need a bit more practice there before rendering a final judgment.
The noise reduction is another area where it works really well in some cases, and yet hardly at all in others. I need to figure that out some more. But the nice thing is that when judiciously applied, it seems like the noise reduction and sharpening (working together) can improve the image, and yet not destructively make the image lose some of its 'Foveon' glassine look. That's paramount to me, otherwise there's little reason to work with a a Foveon sensor to begin with.
I'm not sure about how I feel about unsharp masking being applied only at print/export time: yes, you usually only have to do that to match the limitations of your external devices, but the preview window is rather small to make very important decisions about USM settings, even if you can easily zoom to any level of magnification. On the plus side however, I like that my final image doesn't have tio be saved in some 'ugly' rendition just because it needs to be printed that way. I can save my export/print settings too, so its not like I have to 'dial-in' every setting every time I use them. I guess its just that the small preview window doesn't let me see enough to have total confidence in my settings.
Everyone's fears about the lack of SPP's 'Fill-Light' feature should be partially calmed by the fact that you can achieve the same effect in most cases through tweaking about three interactive sliders The only true downside here is that there's no easy 'negative fill-light' control (or nothing I have yet found, unless you go completely wacky on the curves, and that still doesn't give you the same surreal look as SPP).
My last concern is that my images' histograms in Silkypix may look nice and full, but upon opening the images in another application, I may have a large chunk of unused brightness levels. Upon further inspection though, in most cases, one colour channel or another was using up that space, and only the Luminosity or a couple of colour channels were incomplete. in GIMP, Capture One 4, and Irfanview 4.x, the output images all looked identical. In Corel13, the image looked rather flat, but this was at work on an LCD monitor that has no colour profile, and so each application is similarly display challenged. I should add that the Corel histogram still matched all the other apps. But the fact that there is sometimes a difference (between Silkypix' histogram pre-export, and another apps histogram with the exported file) is a little disconcerting.
If my final tests can produce an image that matches or exceeds my current workflow(s), it will be a no-brainer to buy this, even at its somewhat elevated price-point. Overall, it looks like that could be the case. Here is one RAW developer (other than SPP) that actually seems to 'try' to preserve the Foveon look, as long as you keep conservative in your use of controls.
