I must say that I think the camera (and photographer) did an excellent job getting the right exposure for that shot. A lovely blue-eyed pink baby. I think mum will love how that one looks. If the others are like that too then I think in this case a mostly 'hands off' approach might be the one to go for. A slight increase in contrast or 'clarify' function is all I would change in that last photo.
The edited version has also lost much of its colour. A high key edit can suck a lot of colour out of an image. I posted a tweaked image a while back in another thread
that shows the effect quite clearly. Just luminance tweaking there with a huge effect on colour too.
Whoops... Just noticed I had my (uncalibrated) monitor still set to a slightly less bright preset when viewing this last photo. Which makes me want to suggest an additional slight lowering of the brightness setting too.
When in doubt..... Press the shutter.
