It is ghosting.
Word.
It's a slight version of what you see on the left of this image caused by the camera or subject moving during a slow shutter to burn in the background light. The main light being a strobe, the background being a hot light.
Very early 90's! :-)

Yup. Well done, Tim.

Tim explained it best.
while what tim described in axis lighting is correct in possibility, axis is typically fairly flat low shadow lighting producing a more flat image. the particular image has some high contrast with more concentrated light which doesn't follow typical axis light solution to high contrast problems.
it goes to what i suggested earlier in how it was described to me by kodak in their early entry into the digital slr release with how the sensor reacts to sudden change in contrast.
with the arrangement of the red, blue green, as well as depth, the sensor can become restricted in what it stabilizes in the image process and it must compensate in some form to account for high contrast based on how the pixels are overlayed. in other words, rather than being exact in accurate change of contrast it is compiling the pixels based on best estimate, in essence creating mud due to reaction time in processing which in turn creates the line. again, take note of the areas of low contrast on either side of the model and there is no line...the sensor was able to distinguish the subtle change unlike the areas of greater contrast difference.
fuji made an attempt to rid this with its super-ccd honeycomb sensor rather than a square pattern and for anyone using the s2 it was a noticeable difference under similar lighting conditions. their problem was more in marketing the concept of getting twice the count with half the sensor, but the imaging did show improvement over other "square" patterns for this problem. it (super ccd) still remains a pretty stellar approach in both color and depth.
also, this actually isn't just a digital problem, as scattering ions in film reacts much the same way. the best way to solve the problem is to either throw some overhead or back light onto the subject to force a more subtle change in contrast. when doing so the line will disappear with more light on the subject but then one runs the risk of blown highlights...similar to using a sledge on a finishing nail. finding the balance is key.
For the record, let me be clear. I am not disputing the possibility of Hollywood fakery, news hoaxes and media complicity. I am stating for those who were not in the know, that photoshop masking, and 3-D modelling composite masking is not the ONLY possible answer to some of the anomalies and artifacts that we see in the low res, and even high res videos out there. As with many things on this earth, there are two sides to every story, and not one possibility to answer all we see.
This was the only point I was trying to make.

Mitch. Hope you won't say I'm moving the goalposts - I just wish to move on to more momentous problems observed in the 9/11 imagery - and widen the spectrum of our analyses. After all, it is riddled with an entire repertoire of absurdities/aberrations. I trust you'll agree that we need to look at the 'bigger picture' - so to speak.

But the picture looks terribly green screened or cutout to me. You will counter that is the point.
So now we can discuss the black line and the thickness of the artifact. Why is the outline around the model not black then, if that is the most common error in the device? Secondly why is it not thick and heavy?
Third and least importantly why are we discussing "very early" 1990s? 10 years prior to the thick black lines above. That is not quite the right era for digital photography.
http://en.wikipedia.org/wiki/Digital_photography (The only sentence I see that should truly be investigated is the last one, that offers no citation among other things.)History
Main article: History of the camera#Digital cameras
The first recorded attempt at building a digital camera was in 1975 by Steven Sasson, an engineer at Eastman Kodak.[1][2] It used the then-new solid-state CCD image sensor chips developed by Fairchild Semiconductor in 1973.[3] The camera weighed 8 pounds (3.6 kg), recorded black and white images to a cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image in December 1975. The prototype camera was a technical exercise, not intended for production.
The first true digital camera that recorded images as a computerized file was likely the Fuji DS-1P of 1988, which recorded to a 16 MB internal memory card that used a battery to keep the data in memory. This camera was never marketed in the United States, and has not been confirmed to have shipped even in Japan.
The first commercially available digital camera was the 1990 Dycam Model 1; it also sold as the Logitech Fotoman. It used a CCD image sensor, stored pictures digitally, and connected directly to a computer for download.[4][5][6]
The first flyby spacecraft image of Mars was taken from Mariner 4 on July 15, 1965 with a digital camera designed by NASA/JPL.

Mitch Matrixx wrote:2) Ask the photographer why the ghosting is not black. Perhaps the pic was in Lightroom or PS after the fact, or perhaps this is a case of Halo-ing, rather that outlining also described.
Mitch Matrixx wrote:3) Seriously? I'm a little surprised at your 3rd point and uncooperative twisting of data. I never said, nor does the article state anything about "very early 1990's data, or technology", more specifically, the "very early 90's" comment was inferring the look of the Model and the setting, lighting and shot etc., come on.
GHOSTING, it's a byproduct of your x-sync and flash setup.
Your flash is faster than the 1/200 x-sync you used. As the ambient light wasn't low enough, it registered for the full 1/200s, resulting in a ghosting effect.
If you want to avoid that you have a couple of solutions:
-Try to avoid any movement of the model
-Use a faster x-sync, if not possible with your camera, check the new PW TT5
-Make sure the ambient light is two stop darker than your model
-Align the moving parts of your model on a darker part of your background
-Add another light behind the model to light her contour (i use this all the time with sport photography in bright daylight)
-Etc, etc...

Look you said very early 90s. So I have to assume that is the date of the picture as well. That is your caption pal. Do not dodge the issue. Are you trying now to argue that an early 90s picture was taken on a 1975 prototype camera or what? Or are you trying to argue an early 90s shot was taken on a late 90s camera?
Either way. You are not making sense.
BTW. I was not saying the timeline of digital photography in the sense you claim. I was saying you are posting early 90s digital photography to make a case for late 90s digital photography. Why not use images from circa 2001? Of course I know CCDs existed long long ago. I used them in the 90s in fact when they were becoming commodity items.

Oh, I see what you did there, how you... flipped that...![]()
You can cherry pick with silly remarks all you like. I included the picture as an example, it was the best one available on the real photography forum I linked to. Do a little web digging for yourself, you just may find the specific black ghosting, pre-echo, halo, ringing etc. All of which I am about to school you in over at the more appropriate thread found here: http://cluesforum.info/viewtopic.php?f=27&t=1222&p=2369988#p2369988
Please bring your thinking cap, and your reading glasses if you intend to have a genuine discussion.
How very funny. You have absolutely nothing. So we all now can move on. In a few months come back with something I guess. For now there is nothing to talk about. Bye for now.simonshack wrote:Mitch,
