OK, ISO1600 explains the noise in the 2nd shot (chauncey, if you can't see it, look at the darker skin tones around the chin and neck).
However, there is also some present in the first (the black stripe in the graffiti behind his head looks speckly i.e. chroma noise). You shouldn't really see this at ISO100, so I guess it has come somewhere in the PP. You could get rid of this by doing selective noise reduction on the background, but perhaps it's best to find out why you are getting this noise in the first place.
I'm not sure how the originals looked, but if they were underexposed and you increased the exposure in PP this will increase noise. Generally the advice when shooting high ISO is to expose to the right and then pull back the exposure in PP, which gets rid of some of the noise, especially in the shadows. I guess it must've been pretty dark in the first shot, being as you were at 1/60, f2.8, ISO1600!
When you say "loses a lot of the sharpness", at which point in PP is this?
Did you shoot in RAW? What software are you using to PP?
i shoot in RAW, and looking back at it, the images were a bit under exposed, so i did have to increase the exposure value a bit in pp. so it's safe to say that you were correct in thinking that. and yes, i really didn't have alot of light to play with, but i was very impressed with how the camera lense combo handled the situation. but coming from a 300d every little thing about the 30d impresses me
. now about noise reduction, due to the fact that i really haven't had much success with the process, it's really the last thing that i do in pp. here's an example of what i'm talking about:
Exposure: 0.017 sec (1/60)
Aperture: f/2.8
Focal Length: 45 mm
ISO Speed: 1600
(also did the "eye treatment" that i think bronco was referring to.) the image seems just a tad soft to me. i know my shutter speed was a bit slow, but it's still a good representation of what i'm talking about. this was done with noise ninja at a low setting.
