CPI Full-Spectrum Photography 3 — Questions and Answers
Question 1: When photographing a reportedly haunted interior with a full-spectrum camera, which white balance setting is recommended as a neutral starting point for UV/IR captures?
- Auto white balance (AWB)
- Custom white balance set on a white card under the investigation light source (Correct answer)
- Cloudy preset
- Fluorescent preset
Correct answer: Custom white balance set on a white card under the investigation light source
A custom white balance calibrated on a white card under the actual scene lighting provides the most neutral and repeatable color reference for full-spectrum images.
Question 2: Which ISO setting trade-off is MOST important to understand when shooting full-spectrum in a dark investigation environment?
- Higher ISO increases resolution but reduces frame rate
- Higher ISO increases sensor sensitivity but introduces digital noise that can mimic anomalies (Correct answer)
- Lower ISO requires a wider aperture which reduces depth of field permanently
- ISO has no effect on full-spectrum cameras after the hot mirror is removed
Correct answer: Higher ISO increases sensor sensitivity but introduces digital noise that can mimic anomalies
Increasing ISO amplifies sensor sensitivity but also amplifies electronic noise, which can appear as false artifacts or anomalies in paranormal review.
Question 3: An investigator captures what appears to be a glowing mist in a full-spectrum photo taken outdoors at night. What environmental factor should be ruled out first?
- Solar flares affecting IR sensors
- Breath vapor, fog, or high humidity reflecting the camera's built-in IR illuminator (Correct answer)
- Geomagnetic storms distorting UV capture
- Battery discharge causing sensor voltage artifacts
Correct answer: Breath vapor, fog, or high humidity reflecting the camera's built-in IR illuminator
Breath vapor, fog, or humid air illuminated by an IR light source or flash appears as glowing mist in full-spectrum or IR images and is the most common natural explanation.
Question 4: What is the significance of using simultaneous full-spectrum and standard visible-light cameras at the same location during an investigation?
- It doubles battery consumption and helps estimate investigation duration
- Comparing both images helps differentiate genuine anomalies from IR/UV artifacts or reflections (Correct answer)
- Visible cameras must be present to legally document evidence in most US states
- Standard cameras counteract electromagnetic interference from full-spectrum units
Correct answer: Comparing both images helps differentiate genuine anomalies from IR/UV artifacts or reflections
Running both camera types simultaneously allows investigators to compare images and identify whether anomalies appear only in the UV/IR bands or also in the visible spectrum.
Question 5: Which lens characteristic becomes MORE problematic for a full-spectrum camera than for a standard camera?
- Aperture size limits light in UV wavelengths
- Focus shift between visible and IR/UV wavelengths causes images to be soft when focused visually (Correct answer)
- Longer focal lengths block UV light entirely
- UV light causes permanent damage to autofocus motors
Correct answer: Focus shift between visible and IR/UV wavelengths causes images to be soft when focused visually
Lenses are designed to focus visible light; infrared and UV wavelengths have different focal points, causing focus shift that results in soft or blurry full-spectrum images unless corrected.
Question 6: In the context of CPI methodology, what does 'full-spectrum video' add to a paranormal investigation beyond still photography?
- Video captures sound frequencies in the UV range
- Continuous temporal documentation allows investigators to correlate movement or changes with other simultaneous equipment readings (Correct answer)
- Video files are smaller than RAW still images and easier to store
- Video mode disables the IR-cut filter temporarily in unmodified cameras
Correct answer: Continuous temporal documentation allows investigators to correlate movement or changes with other simultaneous equipment readings
Full-spectrum video provides a continuous time-stamped record that can be cross-referenced with EVP, EMF, and temperature data captured at the same moment.
Question 7: Which of the following is a best practice for documenting a full-spectrum photograph as potential paranormal evidence?
- Apply heavy sharpening and contrast filters before sharing
- Record camera settings, GPS coordinates, time stamp, and present investigators at the moment of capture (Correct answer)
- Delete all images that also show mundane reflections to avoid confusion
- Convert all images to JPEG immediately to reduce file size
Correct answer: Record camera settings, GPS coordinates, time stamp, and present investigators at the moment of capture
Proper chain-of-custody documentation—including time, location, settings, and witnesses—is essential for any image to be considered credible paranormal evidence.
