Analyzing Pictures in Paranormal Investigation
This is a summary of the Society for Psychical Research (SPR)'s guide to analyzing pictures in paranormal investigation.
Purpose
-
Extract reliable info from photos taken on-site or provided by witnesses.
-
Preserve evidence integrity and make your conclusions reproducible.
Golden Rule: Preserve the Original
-
Immediately make a working copy; archive the untouched original (external drive/cloud).
Forensic-Style Workflow
-
Create a folder per image.
-
Keep a change log (simple text file) in the same folder.
-
Edit one parameter at a time (exposure, contrast, etc.).
-
After each change, save as a new file with a clear name and log exactly what you did.
Third-Party Photos
-
Ask the sender: why was the photo taken, what they think it shows, where/when it was shot.
-
Check filename pattern (manufacturer-style vs. “ghostpic.jpg” → likely edited).
-
Compare claims with metadata (EXIF). If details don’t match, proceed cautiously and verify.
Metadata (EXIF) Basics
-
EXIF can reveal camera model, time/date, settings, and sometimes location.
-
Useful for checking flash use, shutter speed, and consistency with the account.
-
Caveat: EXIF can be edited or erased—treat as helpful, not infallible.
Viewing Tests (Blind)
-
Ask multiple independent people what they see—no leading prompts.
-
Avoid group sessions/social media (contagion of opinions).
-
Record “nothing seen” responses too; they matter.
Good Practice
-
Avoid random heavy edits; systematic, logged adjustments only.
-
Keep an open mind; consider normal causes first—genuinely anomalous images are rare.
-
If you think you have something significant, seek expert review (e.g., SPR) before publicity.
Quick Checklist
-
Original secured
-
Working copy + folder + change log
-
Stepwise edits saved with clear filenames
-
EXIF reviewed & compared to account
-
Blind viewing feedback recorded
-
Conclusions cautious, alternatives considered
