Hi all, I need help to identify an artifact in an image. It has been suggested that it is lens flair but Im not so sure, I think it is a problem with the camera's sensor. Ill post the image below any help will be greatly appreciated.

Thanks judge360

Hi Judge and welcome, I would have to first ask, is the original a digital or film image? Hard to say what it is as it seems like such an odd shape,is this the first time it has ever happened? Some information on the camera and lens used would be good, are they both new or secondhand? Have you done any PP on this or is this how it came out from the camera?
 
Do you smoke?
Its the sort of shape/size I associate with fag-ash on negatives when scanning.
Had a fag on when changing a lens?
- Is it only on this one image?
- On all?
If on just the one.... and you smoke, and changed lens before taking that pic... and its not in any others... could have been 'cleared' from the sensor when the mirror flapped.
 
Personally I think Mike attempted to be very helpful. I guess he assumed that you had taken the shot, asked a series of pertinent questions relevent to the subject that you can't answer because it was taken by NASA, and then you get snooty when he gives a tongue in cheek response !

Not getting snooty at all, I was told this forum was the best for expert opinions which is why I brought this image here for analysis :)
 
This Forum has lots of talented people who could give an informed opinion on the subject, but I'll wager that the likes of NASA has got real experts falling out of the doors.

Could be an angel aswell eh ? :bonk: lol

Surely there's someone here that has an explanation as to what the artifact is in the image ? Can anyone tell if the image has been edited in any way ?

Hi judge, welcome to TP! Don't worry about the uh, robust comments from some of our less well house-trained citizens.

I'd say it's a processing flaw. You'd likely see it on lots of images if it were anything on the camera.

But of course it could be a Martian...

Thank you for the welcome Jon :)

A processing flaw wouldnt happen on every image would it ?

Depends on what was causing it. If it were a sensor flaw, it would tend to show on most images and would be a tad tricky to fix in the circumstances. Is that shot from the NASA site? Looks a bit rough compared with the published stuff I've seen. Forgot to say above: Most uncharacteristic of flair, so I wouldn't think that is the problem.

Yes the image is from NASA, the link I posted is a direct link to the image on NASA's website :)
 
Sorry - hadn't checked. Just had a look at the NASA site, and the first few shots show a similar mark so there may be a flaw on the sensor or something. Probably enough to get the UFO nutters excited, but that doesn't take much. Doesn't cover much in the frame, so probably nothing much to worry about.

Jon thank you very much, your opinion on this is enough for me :)

I do own a UFO forum lol, and sometime's there are image's and video's I cant find answer's to. This was one of them, and your explanation in IMO is the the most probable.

BTW Im not a UFO nutter lol, I do serious research into the subject ;)
 
Clearly some kind of sensor defect. It's on the first 4 or so, but the actual shape of the defect changes, so it's clearly not actually there whatever it is. It's an optical or electronic defect. I know nothing of the camera it uses... is it a normal visible spectrum, or was this a IR sensitive camera? It COULD Be flare if there is something crystaline or silicate based reflecting enough sunlight. Light levels are very low on mars and any camera would need to be set to to an exposure level similar to twighlight on earth, so something suddenly very bright in the IR spectrum could conceivably flare.

My money is just some random sensor noise.

Serious research. OK. Each to his own, I guess.

Could be. SETI was pretty serious back in the day.

Did you see DPReview's piece on the Curiosity cameras, David? Excellent stuff and a good example of how a 2MP sensor can a/do good photography, and b/ may be a better choice than one of 20MP.

I think SETI are just as serious as they ever were, especially as exoplanet detection is accelerating at such a rate. I reckon it's inevitable (have you bumped into the Drake Equation?) that they'll find an analogue us in time, but probably not manifesting as a blob on a Mars pic.
 
Yup... you don't even need to have heard of the Drake equation really.. just common sense. Billions of billions of stars per galaxy, and billions of galaxies... of course there's life. It's not visiting is us though :), but the UFO crowd will see what they want in that pic regardless of common sense or logic :)

I'll have a look at the DPreview thing later... off to work in a min.
 
Yep, bound to be life out there somewhere. Could be of lower or higher form than humans but whatever form it is still going to take a lot to travel light years and specifically travel to the few planets that suit lifeforms.
And if they did you would hope they would make a bigger mark than the suspect things witnessed by some alcoholic in the middle of nowhere late at night.

Not on my forum they wont, we provide common sense and logic to the subject. I myself have 20+ years of doing research on UFO's.

Thank you for your input and opinion in a previous post its appreciated :thumbs:
