A brief explanation/tutorial of monowavelength photography experiment. This is mainly used to help debunk orbs which 99.9% of the time are nothing more than dust or pollen particles in the air. To clarify I am not using a LENS filter, I am using gel filter over the drop light I filmed this with.
In the field, we have two methods of doing this test.
1. We will either use a gel filter over the flash (because we can quickly swap them)
2. We will use different drop lights with LED's that produce a specific wavelength of light (rather than filtering white light.)
Either method is acceptable. This experiment can be done with standard spectrum of full spectrum cameras. But, if you use a full spectrum camera, be cautious of light contamination from IR and UV sources.
NTPI is a group of paranormal researchers based out of Fort Worth, Texas. It is our goal to study paranormal activity through the use of the scientific method, experiments, and documentation to prove or disprove the existence of unexplained supernatural phenomenon in any locations that we are called to investigate. North Texas Paranormal investigates both residential and public locations on a regular basis and is available on weekends for field research upon request. We are always happy to help people who are looking for answers about suspected activity in their homes or businesses with the intent to prove or disprove (debunk) the suspected activity in question. Though we are located in the North Texas region, we have group members all over the country and conduct investigations anywhere the opportunity presents itself.
