I recently got a pentax k110d for christmas, and am a bit of a newbie to the dslr world. I was using SCN - 'pet mode' to capture my boyfriend's ferrets running around, and one of the pictures (this happened earlier in a different situation but i no longer have the pictures) came out as having grainy lines across it, at the top and at the level of the whiskers especially.
I dont know if this is a high iso related phenomenon or something i was doing wrong?
the ferrets were playing in a low-med light condition with a dark hallway behind them, but this is the only picture in which the lines showed.
like i said im very new, heres a link to an example,
thank you!
