Whats on the lens ?

Chorcai · 17-11-2009 9:11pm #1

Real newbie question here, tonight I was taking a few pictures noticed what looks like lens flare... the lens is clean checked before and after. So I'm kinda lost now... is it just lens flare or something else going on ?

Do you have a UV filter on your lens. I have had similar problems with night shots and filters.
The solution is to take the filter off if you have one on.

just lens flare. did you have a lens hood and do you have a filter on the lens?

Night shot = no filter

50mm lens hood on the list now.

open up the aperture, the starry lights would suggest that it is closed f/10+??

you wont get such a long exposure time then

A Neutral Density filter can also stop lens flare but will increase the exposure time

looks like lens flare to me...did you not notice it when you took the photo? through the viewfinder i mean...?

I think termonfeckin has just been visited by aliens* and you were there to capture it

I also need to note in my photographic studies of the relationship between termonfeckin and lens flare

I like it. I want to know if you set out to achieve the effect, would you be be to get it?

* very fashionable aliens too

EDIT: The vehicle travelling along the road wasn't an ambulance / firebrigade?

It's just internal flare, you'll notice that the flare is just a flipped version of the light trails. Nothing to do to prevent it unfortunately, except maybe shoot with a prime instead of a zoom presuming you were using a zoom. A hood wouldn't do any good because the flare source is in the frame. An ND filter would if anything make it worse, more glass surfaces for light to bounce off ...

I think its just a reflection of the lights on the wet road to be honest!

Not the white; the blue.

it might also be the lights from the car going away from you if it came from the left of the shot and not from behind you. If that makes sense......

ie the car that is producing the red streams came from a road that is to the left of the shot as it approached its front lights caused the lens flare so you need a lend hood

It's not. If you grab the image and paste it as a layer on top of itself, then rotate that layer 180, with a small bit of jiggery pokery you can make the flare overlay exactly on the streak of the white headlights. IE its internal flare in the lens from the headlights.

To be honest I think it might be god mooning you.

I used the 50mm prime. Maybe I was facing the car's to much and should be at a differant angle. Will try again tonight if its not lashing !

Sorry, but I don't think that is correct. Adding glass surfaces can only add to the problem. To take an exposure, a certain amount of light has to get through, an ND filter will just make the exposure longer and will not decrease the amount of light that that ultimately has to get through.

I would check the lens for any greasy smears on the front and rear elements.

Whats on the lens ?
