On September 2, 2007, a witness in Tatinghem, a commune in the Pas-de-Calais department of northern France, discovered an unusual anomaly while reviewing a digital photograph. The witness reported observing "une forme étrange" (a strange form) on the photograph, though nothing unusual was noticed visually at the time the photo was taken. This represents a common phenomenon that has become increasingly frequent with the proliferation of digital cameras—objects appearing in photographs that were not consciously observed during capture. GEIPAN's investigation revealed two distinct anomalies on the photograph: a larger, blurred spot and a smaller gray spot in the center of the image. The witness had not seen anything unusual with the naked eye when taking the photograph, making this a purely photographic observation rather than a direct visual sighting. The case was submitted to France's official UFO investigation agency, GEIPAN (Groupe d'Études et d'Informations sur les Phénomènes Aérospatiaux Non Identifiés), operated by CNES (Centre National d'Études Spatiales). Following analysis, GEIPAN classified this case as "B"—a classification indicating a probable explanation exists with a high degree of certainty. The investigation determined that the larger blurred spot was most likely caused by a bird or insect passing relatively close to the camera lens during exposure, which would account for the motion blur. The smaller central gray spot was identified as a minor camera defect, likely visible on all photographs taken with that particular device.

Photograph Taken
Witness takes digital photograph in Tatinghem. Nothing unusual observed visually at time of capture.
Shortly after capture
Anomaly Discovery
Upon reviewing the photograph, witness notices a strange blurred spot and smaller gray spot that were not visible during the actual photography session.
Post-discovery
GEIPAN Report Filed
Witness submits case to GEIPAN for official investigation, case assigned ID 2007-09-01795.
During investigation
Photographic Analysis
GEIPAN analysts examine the photograph, identifying two distinct anomalies: larger blurred spot and central gray defect.
Investigation conclusion
Classification B Assigned
GEIPAN concludes probable explanation: larger blur caused by bird or insect passing near lens, smaller spot is camera defect. Case classified as 'B' (probable identification).

"Reported observation of 'une forme étrange sur un photographie sans observation directe lors de la prise de vue' (a strange form on a photograph without direct observation during capture)"
04 Analyst Notes -- AI Processed
This case exemplifies a category of reports that has surged with the advent of digital photography: photographic artifacts mistaken for anomalous phenomena. GEIPAN notes in their investigation that "Ce type de cas de taches constatées sur une photo alors que rien n'a été constaté de visu est devenu très fréquent avec la multiplication des appareils photo numériques" (This type of case of spots noticed on a photo when nothing was observed visually has become very frequent with the proliferation of digital cameras). The technical explanation provided is consistent with basic photographic principles—fast-moving objects close to the lens will appear as blurred streaks or spots, particularly if they pass through the frame during exposure. The witness credibility is not questioned, as this appears to be a genuine inquiry about an unfamiliar photographic phenomenon rather than a deliberate hoax. The GEIPAN investigation was straightforward, requiring only basic photographic analysis to reach a conclusion. The classification as "B" (probable identification) rather than "A" (certain identification) suggests minimal residual uncertainty, likely due to the inability to definitively prove which specific bird or insect caused the blur without additional contextual evidence. GEIPAN's assessment that this case is "très peu étrange" (very little strange) reflects the mundane nature of the explanation and the low evidential value of the sighting.
05 Theory Comparison
BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Mundane Explanation with High Confidence
Given the complete lack of visual observation, the photographic characteristics consistent with known artifacts, and GEIPAN's expertise in analyzing such cases, this incident requires no exotic explanation. The classification as 'très peu étrange' (very little strange) by experienced investigators indicates this falls well within the bounds of ordinary photographic phenomena. No credible alternative hypothesis is needed.
06 Verdict
ANALYST VERDICT
This case is almost certainly explained as a photographic artifact caused by a bird or insect passing close to the camera lens during exposure, combined with a minor camera defect. The GEIPAN classification of "B" is appropriate and well-justified. The case holds minimal significance for serious UAP research, serving primarily as an educational example of how digital photography can create apparent anomalies that have prosaic explanations. The lack of visual observation by the witness at the time of capture, combined with the technical characteristics of the blur pattern, strongly supports the avian or insect hypothesis. This case demonstrates the importance of distinguishing between genuine aerial phenomena and photographic artifacts in the digital age.
