I was in San Diego this past Saturday and took several shots of the skyline at night... As suggested on another thread, I turned up my ISO to 3200. The shots looked fine in live view, so I didn't adjust anything... but when I got home, I found that every shot was grainy... What's worse, when I ran any of the photos through post production (I tried Photoshop, Lightroom, and Photomatix) they turned out even worse!!! I realize it's me and not the camera... Here's 3 of the shots... please tell me what adjustments I need to make for the next time... Thanks in advance!
