Photoshop CS6 (wont pay for monthly CC) 99.9% of time, this is my first option for workflow.
Lightroom (my choice for white balance and noise correction)
On1 Photo Raw (I need to run this on my i7 – 5960 computer for best performance. But will run I7 920 with a bit of patience.)
Luminar (windows) and Luminar Creative Kit (mac only) (verdict is still out, but so far, I like it.
Topaz (best all around plugin for filters)
Nic Color Collection (never count this collection out)
Gimp (when on Linux)
Imagenomic (not as often as once, but still has it’s place)
