I don't know if this is camera-specific or not, but I am assuming it is something I am failing to do, and all DSLRs would respond the same way. Here goes... I have an Olympus E-510. It's the first DSLR I have ever owned. I had it out tonight taking a few pictures of our christmas tree. We have a row of Palm trees out back of our house, and the skyline behind them is dimly lit. I decided it would be a cool picture, so I tried snapping a photo of it, but the camera won't take the picture. I have had this same problem before when trying to take pictures of dimly lit areas, so this isn't the first time. Even when I set the camera on full manual and adjust the settings, it still won't take the picture. I have tried on Auto as well as a few scene settings, too... just to see if it was the settings I was trying. I have an F3.5-F5.6 lens, so I had the F set at 5.5. I tried a number of different shutter times, 60s all the way down to 1s, and none worked. What am I doing wrong here?
