I'm interested in your shooting information
It seems like you were trying to get the longer exposure by stopping down that aperture that small, and by putting the exposure compensation down by -1.7.
But then ISO 1600?
I learned once I took a better look at the photos that I could have gotten a better result from a lower iso... Now I know.
Like I said, first time really doing anything at night.
But what I did, was I put it in shutter priority and made it a long shutter time. My camera automatically closed the aperture because it was getting too much light... I should have thought of turning the ISO down but I didn't think it would matter too much.
