[Help] First night shot - strange light

Click for full size
Canon EOS 40D

Hey everyone, just got this Canon EOS 40D and after reading some posts here on taking night shots, I thought I would experiment. I took several shots at different settings and they all have this wierd lighting affect top center. I'm guessing it has to do with the lights on the house across the street. Kind of a cool effect.

Anyway, any pointers on settings?

Lens flare.

Had those today during my shots. It depends of the lens you use and the available light!

I'm using the 28-135mm kit lens that came with the camera. Is there a way to avoid the flare?

Thanks!

A flare is usually an artifact caused by light spill going directly into the lens. Try changing your angle, or using a lens hood. UV filter can help to some extent, but simply a lens hood+angle change will fix it.

In a situation like this it will be tough to get rid of the lens flare. It's caused by the exceptionally bright (comparatively speaking) point source light by the garage bouncing around between your lens elements. However you can minimize or hide the lens flare.

If you moved over to your right to shield your camera with the tree a bit more it would minimize the flare.

Changing your point of view so that your camera is pointing directly at the light will move the flare into the light and it will be overpowered and, therefore, much less obvious.

Not sure whether you have a filter on the lens, even if it is one to protect it, i do alot of night shooting and used to suffer from the flares quite a bit. i took the filter off of the lens and it minimised and in most cases got rid of it.

If you cant fix it, then find something you can. If you cant find something then break something.

Had a similar greenie appear on some of my night shots a couple of months ago. Someone posted a comment on the Flickr page that echoed what Charliebrown offered up - potentially being caused by a filter on the lens. Sure enough, I had the UV filter on from shooting earlier in the day.

As has been noted several times already, that will probably make it worse. It was night shooting that made me give up UV filters altogether, unless I'm shooting in an extremely sandy or salt water environment.

A lens hood especially on a zoom like yours is definitely your best chance of avoiding flares. As for the filter, I say get a hood first. I do a ton of night shooting on my big 17-55 2.8 IS zoom, and it has a B+W MRC UV filter on it - I've never ever had any flares on any of my shots (check the gallery). Of course, I also never leave home with out its hood.

PS: Dots like that on night shots is the filter, but it's not a traditional lens flare. That's the characteristic of droplets of liquid stayed on your filter and the light is refracting on it.

Thanks for all the comments. I don't have a filter on this lens and I have ordered a hood (was going to get one anyway) so will do some more testing when I get it.
