I take lotsa digital pics and eventually get one or two good ones fit for keeping. By trial and (lotsa) error, I too finally twigged onto taking the pics outdoors on an overcast day for best results - but the snow background Dec-March is a bummer. Digital cameras and gun marking close-ups are made for each other.
I WOULD REALLY like to see (and really NEED) an article in Double Gun Journal or Shooting Sportsman on features/selection of digital cameras and taking better digital pictures. There might be enough "meat" for a two part series.
"Better Digital Pictures For Dummies" - for insurance purposes, advertising, personal gun records or e-mail sharing.
