That smudge on the left is a bird that flew by.
I'll mention that the camera was set on Program mode, where the camera sets the shutter speed and aperture for you. Sometimes you'll read about never using Program mode -- that it's better to use any mode (Shutter, Aperture, or Manual) other than Program. To be honest, I'm amused when some people are so strident about this. All I care about is that I get the picture that I'm seeing in my mind. I've used cameras long enough to know the capabilities of each mode, and why you'd want to use any of them. But when you have light changing so quickly as you do during a sunrise or sunset, I don't want to waste time thinking about settings -- I want to concentrate on what I see in my viewfinder.
Yes, you should learn what each mode can do for you, because Program is not a one-size-fits-all kind of thing. But you're not a loser if you use Program.
