Nice shots that I'm sure dad would be very happy with for the album. Re the saturation thing: I do agree that the originals were a little heavy handed. For myself (if this helps) I always leave the saturation adjustment until nearly last, and I tend to err on the cautious side. Also, I find that greens and oranges tend to be the benchmark - I adjust to get the grass right and, usually, the other colours fall into place.

Cheers
