I've had my camera (Pentax K-S2) for about a year now and it's worked perfect until recently. I have had amazing pictures come out on the manual settings - ISO 800 - f5.6 - 1/00 with a lit studio. I come back the next day with the same exact settings and set up and my pictures are coming out dark. I'm so frustrated and confused, can someone please help me? I read it could be the battery but I'm not sure?
Thanks in advance.
