I got a couple of shots of a friend's child today, which are nothing special, but decent snapshots - I will be photographing him in a couple of days though. Once I loaded the photos on my laptop I realised that his fair facial hair is very prominent, and more so than I would have noticed otherwise!! I would like to know how to fix this PP? What would be the best way? Or is this something I should tend to prior to/during shooting next time?
