Hi all, This is a picture I took with a Nikon Coolpix 4200 camera. Notice the vertical pattern along the picture, I wanted to know whether this is "normal" or not. Has anyone ever experienced this? I´m quite newbie in digital photography, so I would thank you guys if you could explain to me what could be causing this and how I can fix it. The settings for this picture are: Resolution: 4M / Fine quality ISO: 200 Exp. time: 1/161 sec. Thanks!
