The green horizontal line and the 3red marks? I have a few shots with what looks like a mirrored reflection of the lights. It's pretty bad in some of my other pics. I'll post them tonight. Thanks for the help!

Chris

BTW I didn't us any filters or the lens hood.

The 3 red marks are a reflection of the lights on the left side of the pic. The green line also looks like a reflection from possibly the skyline but it is probably out of frame on the left.

The best way is to keep the lens cap on...:blah:

Others will have to comment on less effective ways.

Here's another try. Each element of the lens is coated on both sides to reduce reflections from light sorces that are pointing at the lens. Some lenses have better coatings than other lenses. It looks to me like you are getting reflections off multiple lens surfaces - remember, each element has two surfaces, so a lens with 9 elements will have 18 surfaces that can reflect light.
You have not mentioned the lens you are using, but I suggest you search for reviews on your lens. Some have more flare than others, and a copy of a good lens may be worse than other copies.
I'm still waiting for someone who actually knows whats going on to comment...

Filters often cause more flare in those types of shots.

So, if you've got a filter of any kind (UV filter, etc.), I'd remove it.

I had no filter on the lens. Almost all of my shots last night has this kind of flare Even on the pics I tookfrom a great distance from the bridge I took my pics between 4.5 to 6 second and f/5.

I did notice my wife took some pics with my 20D set at 30 seconds f/8 and the flare is almost gone, see second pic. Maybe I need to take the pics at a longer shutter speedand f/8? :?

Thanks Jim!

5 seconds f/5.6



30 seconds f/8
