what has been done to the image above to get so much detail and sharpness? it seems like it wasn't unsharp mask. There could be some dodging and burning involve but we can't normally get this sort of effect. anyone know how its done?

another example shown below;

There's so much details on the face. how is it done? Notice the colour cast in the image...how do we get those sort of cyan/green cast? its done intentionally to create a different mood i suppose but how?

The images don't load for me...
But I think the cast you are talking about is a cross processed photo, search for 'cross processing tutorial' on google and you'll be on your way.
