Sometimes the reflection looks pretty cool, but then sometimes it may be across someones face or elsewhere that just ruins the shot...and as I said, its aleays from a neon light, like a bar sign....
Well, if you had posted the original I would have enjoyed looking at what is in front of the man.

The light seems to come from something in front of him and peeking between his arm and his chest (hot spot there). This light is so strong that it reflects from the wall on the left and a glass framed something onto the woman's face turned toward the wall!!!

The white reflection on her body maybe coming from the door next to her or another light source at knee level.

What you are looking at here is not flare but one strong green light and several reflections of unknown origins. You were there so you know better than anyone what was going on.

A hood or filter will not help in this case.

"When the exposure is made, the mirror is up and no light from the viewfinder will affect the image. The reason for blocking the viewfinder is to keep any light entering the camera through that area from affecting the metering.

So I think digicamking's solution may have seemed like the answer, I do not see how. When the mirror is up, the only light path to the sensor is from the lens. That is why the viewfinder goes black at the moment of exposure.

Well, I know for a fact that even with the mirror up and light available into the viewfinder image can appear on the file.

How, I don't know, except light can bounce around all that glass somehow and end up where you least expect it. I have several cameras that have a curtain to close over the eye piece to avoid this problem.



I was taking an IR photo a few years ago with an exposure of over 10 seconds. The sun was directly behind my back, the camera on a tripod. I fired the shutter and happened to move away from the camera and left the eye piece cover open.

Image my surprise when i saw this bright circle of light showing up in the image, it was the reflection of the sun.

Just a shot in the dark here no pun intended, but is your lens and or filter both clean?

Playing devil's advocate here. Are you guys sure that this is a reflection coming in through the lens? It looks really rectangular and has sharp edges (compared to reflections in my photos :) ). My Nikon D5100 came with a cover for the viewfinder and the manual says to use it to block light from getting in the shot when you are not taking photos with the camera up to your eye.


No, that cover is to keep light from entering through the view finder and affercting your meter reading, not an issue if you are shhoting manual. In an slr, the mirror prevents light entering the viewfinder from reaching the image sensor.

Am I seeing a similar shaped white rectangle on the back wall right of center? This looks like it could be a bright surface such as a TV screen. I suspect this the source of the green reflection showing up in front of the lens.

Actually the reflection is probably within the lens system, if a filter is in place and counted a part. There is another current discussion on a related green reflection problem, where the sun and a filter was involved. (unwanted green circles- - - by bedgmon)

That the "ghost" is approx the same color as the neaon on the left side, I'd guess it's reflections with a filter and the outer glass of the lens of the light from that sign. $0.02.


This is the exact same thing I was having in darker settings, or, at night, that had bright objects in the image.
I'd noticed I had ghost images, that always occured when there were brighter items in the image, such as street lights, neon signs, headlights, and taillights, etc.
Also, they seemed to follow the color of the brighter object, albeit opacity was low enough to not mask everything under the reflection.
If there were multiple bright objects, I had the same number of similarly colored ghosts, and they would ALL be in the same relative clock position (1 o'clock, or whartever position 1 would be at, they'd all be at the same relative "clock" position).

I found that if I removed the filter (UV/daylight), the ghosts disappeared.
Sooo, I remove the filter at night time activity.
