Its hard to choose a piece of software that comes close to what you want with all that under the bonnet and does it well...
The closest thing I can come up with is Adobe Photoshop with a commecial plugin Nik Software Color Efex Pro - Photoshop has a photo merge capability and a HDR capability with full automation via actions - not as good as specific standalone software.
But even still, I am combining a single piece of software and a plugin... not strictly one piece of software
I have had experience with Color Efex Pro and it is very good. But doesn't do anything you can't do with Photoshop if you know how. However It does give you a side by side preview of filters and effects, which I find very nice.
If it were me though, I would have seperate software
- Kolor AutoPano (for panoramas)
- PhotoMatix (for HDR)
- Adobe Photoshop (with Color Efex Pro) or Lightroom for post-pro
