CPI Full-Spectrum Photography 3

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?

Accepted Answer

Custom white balance set on a white card under the investigation light source

Answer

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?

Accepted Answer

Higher ISO increases sensor sensitivity but introduces digital noise that can mimic anomalies

Answer

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?

Accepted Answer

Breath vapor, fog, or high humidity reflecting the camera's built-in IR illuminator

Answer

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?

Accepted Answer

Comparing both images helps differentiate genuine anomalies from IR/UV artifacts or reflections

Answer

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?

Accepted Answer

Focus shift between visible and IR/UV wavelengths causes images to be soft when focused visually

Answer

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.
