For this image I did all the post pocessing in Linux, just as a personal challenge.
I used:
Ubuntu linux
UFRaw Raw opening and color curves
Gimp sharpening and resizing
This was destructive editing and only saved the result as jpg, if I want to correct something I'll have to do everything all over again, from the original file
I didn't do any spot editing which would mean i have to use layers, and while i have done , I still do not feel comfortable doing it and would probaly use the windows tools I have.
I feel it is oversharpen, which I did once at full scale and it looked fine, resharpening after resizing was not needed.
Regards!
