so i'm kind of new to photography and all, and i have a problem i'm not sure how to take care of. a few weeks ago i went down into the southside (pittsburgh) on a friday night and took some pictures, so as you can imagine, there was a lot of lights. i took quite a few pictures, including some of the city across the river. i was so excited to get them developed, and when i did, i was sort of disappointed. i mean, they look cool i guess, but i wanted my pictures to turn out how i saw them. there's a lot of light "tracers", hopefully you know what i mean, i'm sure you do. but they're all over the place, and mostly all of the pictures are blurry and have streaks of light all over the place. how should i set the aperture/shutter speed and what not to adjust to the night and the light (without using flash) for clear, sharp pictures? thanks!
