my pictures are seeing double???????

HI
I have a new Coolpix 5700 and many of the photos I've taken with the digital zoom on have that double vision effect when I open them on the computer - thumbnails are ok......? anyone knows why???

Thanks

Nathalie

what type of shutter speed are you using??long or short exposures??

sometimes in night shots or long exposures if the camera is not stable you will get that "double look"

No it was real quick mostly 1/1000 - 1/4000 in sunlight....

Could it be that I shot those pictures through a window????

Thanks for you help

nathalie, congrats on the coolpix 5700, it's a great camera. can you post some examples of the double-vision pix?

Well

I tested and took pictures again through a window (same) and picture came out fine. So it had to be something else. Could it be a default in the Compact Flash card????

Thanks for helping

nathaliedoo, I looked at your pics and the shutter speeds and all that looks good... and camera shake should not be a problem, unless you are REALLY shaking the camera.

I would suspect something may be wrong with the camera.. on your cool pix is there a "reset" button?? if so try to reset it, then reformat the media card in camera and see what happens...

It sure looks like camera shake to me. I have not heard of any problems with this camera of this sort as I also own one too.

I would continue to take pictures and see what develops. I do not beleive that the compact flash card can cause this result, so I would watch the shutter speed and be careful of the latency of the shutter in particular.

Please let us know the final outcome.

Sometimes Digital Zoom creates problems because it crops the picture and reinterpolates it in the camera. I have turned it off in my camera due to this fact.

It could very well be due to the window. If the window is double glazed you sometimes get the image twice depending on what angle you're shooting at. If you are straight on to the glass there shouldnt be a problem. However the further from the 0Â° you get left and right, the more light gets refracted differently and moves the double image further apart.

I took a subsequent look at the two images you offered and submit these observations for further consideration.

With regards to the â��treeâ�� image, I do not believe the EXIF data as it relates to the image shown. I find it problematical to accept that the camera would select an exposure value of 1/4000th of a second at f6.7 for this specific image. I recognize that is what it tells us, but it does not make common sense to me. I wonder if the shutter latency question is a factor here? Or, could it be the ability of the shutter to lock both the focus and exposure, when the shutter release button is partially held down? If it was locked when the camera was pointed elsewhere, and then the camera was repositioned for this exposure, then it adds up. But, the other subject when the cameraâ��s shutter was partially held must have been a very bright light, the sun, or equivalent.

Second, with regards to the fence image, it is realistic to see camera shake at that high magnification - 284.8mm - and at just 1/60th of a second shutter speed when the camera is hand-held. So, I think that problem is easily explained.

Have you learned how to properly hold a camera? I do not mean to be insulting, but there is a proper way to hold a camera, especially with a long focal length and good form might be of help in this case. Especially, with these smaller D-SLRs, which are so tiny to handhold, at least in my hefty hands.

My final thought. In the past, I have taken pictures through specialized plate glass windows in office towers and experienced strange and wondrous results. These results were due to the thickness of the glass plating (1/2â��. Â¾â��, 1â��) and the various surface coatings on the exterior for architectural reasoning. When shot perpendicular to the glass plane, it was fine, but when shots where taken on angle to the glass plane, distortions resulted.

Konador, as they old saying goes - Great minds think alike, and fools never differ - let us be great minds, OK?

You persist in amazing me, not only with your talent, but with your brilliance and vivid understanding of the world, and at just 15 years old too. Simply incredible.

Ben, I look forward to telling others in the future that I new you â��whenâ��. Please continue to impress us all; it is astonishing.

Thanks for all your response. Here are my comments on your reply:

If it is the window, why doesn't I encounter the problems each time I shoot through it? Angle? Makes sense.

Regarding shaking, well, I know how to hold a camera and honestly, the Nikon Coolpix is not so small and more similar to a 35mm. It could have been a possible explaination if most of my pictures were like this but it's not.

Regarding the tree EXIF it is the good aperture and shutter information, I set in manually, does that help???

Yes there is a reset button on my camera, I may just use it if I encounter the problem again. If this is a camera problem, I should certainly report it before the 30 day instore warranty ....

Thanks again for all your comments!

To be continued!

You may have set the shutter speed and aperture manually, but I wonder if the camera overrode these settings somehow to deal with the reality of the situation? How did you determine in the first place that 1/4000th of a second was needed in this situation? I suspect that the camera tried to take a correct exposure, but certainly more investigation is required.

To handhold a camera with a lens set at 282mm is very hard, even for a pro, especially at 1/60th (fence shot), so I am not too surprised at that result. Do you agree?

HI again

First, when I decided to shoot that blue sky with the tree, my main idea was to test the auto focus of the camera and try the zoom. I shot at different aperture and speed, they all came out double vision. The shutter and aperture of the posted picture were the ones rendering the best light and blue sky. I also shot the fence, fallen leaves on the ground, all through windows and they all came out double.

I definitely agree that something is strange. Was it an isolated error of the camera, my mistakes or the window??? That is the question and I am only curious about it especially to make sure the camera isn't defective. All inputs are certainly appreciated. Be assured that I don't want to make an argument over your comments which are greatly welcome. My mother language is French so it's possible that some sentences may sound different than what I mean!!! I will try to shoot the same tree at the same aperture and shutter and post them today.

Thanks for your help

can I suggest something? Does the window open? If so, take a shot through the window, then leave the camera exactly the same, but open the window (or step outside). If the images are still double not through the window you can count that out :)

Well, by the time I could have some time to try to take the same picture of the trees the light was not as good and I could not reproduce the exact situation. I took the shot at 3 different settings and they came out ok regarding the double vision effect....

p.s. no I can't open this window...

A thing I'm almost sure about is that when I shot the pictures I checked them on the screen of the camera and they were ok. later on I checked them again and that double vision effect appeared. It was showing ok for a fraction of second and suddenly the double appeared.... strange.....

Hello,
i have a CP5700 and have never had this problem. I don't shoot in digital zoom due to the lower quality obtained. I have a 2x zoom add on lens that seems to work well, and wasn't super expensive. This camera takes some time to get used to and to learn the features. As with any product, there are things I like and things I don't like, but in general I am able to get great images from it. If I don't, they are close enough to doctor up in Photoshop to be happy with them!

Good luck and have fun
