DSLR Mirror Problem

Hello!
I am very new to DSLRs and I am quickly learning more and more each day. However, there are questions that I cannot seem to find answers to by googling. For instance whenever I am in the video mode on the refurbished T2i i just purchased it creates this weird mirror image of a subject in my photo when there is too much light. Is this a normal thing or is there something wrong with my T2i.

In the sample image below the wind chime to the left has a ghost mirror image to the right. It seems this happens a lot. When I change the ISO its not as noticeable is this normal?

Thanks so much!

That looks like ghosting. Are you using a cheap filter of any kind? If so, get rid of it.


I'm in Canada. Isn't that weird!

Yes there is a cheap filter on it but after removing it. The image looks better but that ghosting effect still happens.

Post another picture if you can. Perhaps you are getting a flare from shooting towards the sun.

Thanks so much again for all your help!

Here is two photos the first has a filter and the second does not. I know that i'm probably being nit picky since in the second picture the ghosting effect is hardly noticeable but if there is some way to remedy the problem :) it would be great.

My monitor leaves a lot to be desired, but I'm not seeing any ghosting.

Leaving that aside though, check your shutter speed...It may be too low for handholding or for stopping motion of the chime itself.

adjusting the shutter speed helps a little bit but there is still ghosting :(

I see it. Someone posted something like this a while ago. I think the conclusion was that because you are shooting into a light source, you can see the reflection of the light bouncing off the mirror.

During the taking of the picture, the mirror is flipped up, there is no reflection from it.

This is normal flare when shooting into the light, massively overexposed and then seeing some reflections and loss of contrast in the dark areas. The image of the chime in the filter picture is because the chime is a shadow in the bright part so the reflected light off of the sensor and back off of the filter will have a shadow in it the shape of the chime.

The unfiltered shot is much better since you get rid of a reflection surface and some light scattering. All lenses will flare at a least a little if you overexpose a large bright area hard enough with dark areas elsewhere in the frame but filters make it much worse. Unfortunately a lens hood wouldn't help this image because the light source is inside the frame but a hood is a good idea anyway for other cases where the light is outside the frame but still landing on the front element.

This is why it is so important to remove filters during backlight situations or when there are light sources within or just outside of the frame. Also look how much sharper the unfiltered shot appears, especially around the gold work.

Is it shot through a window?

Which lens are you using?

Are you using a hood on the lens?
I suspect not - what your problem seems to be is flare, not ghosting.
Flare happens when a bright light shines across the front element of the lens - a hood stops this - from just outside the area of the image.
If this were ghosting there would be a second fainter image in the frame, offset from the main image.
And yes a filter may make the flare worse.

PaulB beat me to it... It looks a lot like flare, in which case a lens hood would help. What lens are you using?

Thanks so much everyone for your help!

the shot was taken normally and not behind a window.
the lens is a 50mm 1.8 i think its nickname is the nifty fifty im not entirely sure.
I dont have a lens hood on it but if it will help with the flare I am definitely going to go purchase one :)!
