|1 - Summary of the cases classified as "C" by GEIPAN:
- "Non exploitable due to lack of information" and
- "More a case is strange, more it requires consistent information to be classified, otherwise it will be classified C. It is important to note that cases classified as "C" depends of the level of investigations progress and are absolutely not the same as the cases classified A/B/D1/D2, since it's about surveys on which actually GEIPAN could not decide. "
With regard to the expertise of photographic documents, as specified in the methodology of analysis, it can only be done in the presence of the original document: "The image file should always be collected in its original format, after having been, at most, only be copied without any change. "
2 - Expertise of documents:
Unfortunately, it is very common to receive requests for non-original material, meaning that either the photography has no metadata or that the author can not provide the original format.
No work can be done in this case and the document is unusable due to lack of data.
3 - Evaluation of the case:
A first empirical evaluation, visual and subjective, can of course be made by the analyst but it should in no way take precedence over the intrinsic quality of the materials provided.
In other words, we should not rely on our first impression (even if "it is obvious") and only work on an original document (which may or may not confirm this) to prove it.
4 - Classification of cases:
All these documents are received daily by those who collect them (UFO investigators, MUFON, etc..) and are sent by people, witnesses, who do not have the trained eye of the analyst or the habit of seeing them. It is thus normal they consider an object that they photographed, known mostly by the analyst as common and seen from an unusual angle, as inexplicable.
Unfortunately, they do not know that to manipulate a photograph destroy usable information.
We have then a second-hand and/or resized and/or without EXIF data document ...
All these cases, which constitute the vast majority can not be classified in any way other than "C", unless new information reaches the analyst in the meantime.
