Happy Hour, The dsc-h2 is a P-shooter, goodolemargaret likely has little to no controll over such aspects and understanding exposure works best if one has full conrtroll over exposure.
goodolemargaret, Focusing a camera like that generally requires holding the shutter button for a second or two untill the AF (auto focus) has found and focused on it's target, this applies to delay timer shots as well. However if you are trying to take photos in low light and/or night shots, AF can not find the target and thus will not focus properly. Also naturally AF can not focus on a target that is not present at the time of focus in the event of self portrates, Some object must be there to focus on the coorrect spot otherwise the AF will focus on the nearest visabal target with in the focusing brackets. Stepping into the frame after words will result in out of focus subject.
