hi momatx, and welcome to
RP.
well, as a novice, i think you've done quite well. you brought out the image more and cleaned up a lot of the damage.
on the downside, i think you've over-contrasted a bit here. the whites are a bit too white, at least in the dress. and your cloning/smudging is a bit off here and there in the background.
i had a try with this image too, and i found that the lighting presented some problems i wasnt expecting. i ended up using brightness/contrast, curves, levels, histogram adjustment and clarify and some more than once. and i also used a hue/sat layer to desaturate and adjust lighting a bit. i kept a bit of the sepia rather than go completely black and white. this tends to preserve the 'old' look a bit.
and that was the first part of what i did. that was all to get the lighting more in line and to bring out some more detail.
after that it was mostly cloning in the background followed by some airbrushing and cloning on the face and dog. i removed a number of spots on the dress also. and somewhere in there was a very light 'digital camera noise removal' to lessen the noise. this latter one also surprised me a bit as i was expecting to have to use a medium to heavy setting and ended up going very light with it.
and for a final treatment i airbrushed over the background and did a 'push' (heavy smudge in photoshop) on the face for small detail work. i find that clone, when you get down to about a 4 pixel brush or so is not as good as a simple push brush for the very small work.
