And if so.....I need help! Basically, I just got two rolls back, one showed up blank and the other, only 3 shots showed up totally too dark anyway.....should i consider getting a flash? If so, does it need to be camre specific? Or maybe I should just keep the aperture wide open the whole time??? and sacifrice depth of field...hehe...not that there is much anyway!....what do you guys think?
