Pulsed or strobed lighting freezes moments in time.

To help us see more clearly in the darkness I realized some time ago a new alternative lighting technology was needed, I experimented with pulsed modulation as an alternative technology I also provide alternative colours for new experimental procedures.

The DL was initially designed to increase the observation potential in low light conditions, experiments showed that the system could be used with still cameras using a new procedure.

The DL system is an experimental multi function, low power, frequency pulsed LED lighting system.
It is an experimental alternative lighting for use with still cameras, camcorders and personal observation.
DL incorporates three LED types - Blue, Ultraviolet and Infrared.
An array of controls allow the user to experiment with various setting, I recommend recording of location, conditions and settings.

In low light/dark locations the blue and ultraviolet suited to human observation, still photography and camcorder when used in 'normal' lighting setting.
The infrared LED's are for use with camcorders capable of 0 Lux night vision.

Each LED colour is individually switchable to allow the user control to suit the location and relevant technology in use.
The frequency of the LED driver can be set in several ways, the 'MODE' select switch selects the following functions-

MODE SWITCH settings-
1, A Sweeping/recycling frequency pulsed setting - high and low range selected by the on/off/on switch.

2, Pulse frequency at an Infrared harmonic

3, Pulse frequency at a Blue harmonic

4, Pulse frequency at an Ultraviolet harmonic

5, Manual frequency control - for experimental use.

All combinations of LED selection and MODE select switch settings are permissible and encouraged for experimental research. Example - Using the blue LED's at the Infrared frequency creates a light vibrating at a none harmonic frequency.

The on/off switch also controls the high/low range of the pulsed frequency, experiment using both settings.

Initially set the MODE switch to position 1, to cover a varying frequency range.
If using one individual colour set the MODE switch to its corresponding setting.
(2 = infrared, 3 = blue, 4 = ultra violet)
Experiment with various combinations.

Enhanced human night vision
My research concludes when we are in a low light environment (no artificial lighting) our eyes revert to a night vision mode, they become more sensitive to blue and ultraviolet light.
Selecting the blue and/or ultraviolet light LED's and experimenting with the MODE select switch a wide range of experiments can be conducted.
I advise keeping note of equipment settings, as if during later examination of recorded events an unusual image is recorded, repeating the experiment with the same settings will allow on a future investigation to repeat the experimental procedure.

Still photographs- in dark locations
The following applies to both digital and film photography.

My recommended method of still photography is as follows.

The use of a tripod is advised, alternatively improvise a firm, stable platform.
Turn off the cameras built-in flash.
Ideally use a camera with a manual shutter speed control and experiment with settings from 2 seconds to maximum duration shutter open duration.
If possible experiment with other settings, such as ASA, exposure etc
During long exposure photographs ensure any persons present remain completely still or remove them from the scene before taking the photo. (Advise anyone in the photograph not to look directly at the Ultraviolet light).
It is imperative that during the exposure the camera does not move.
If the camera does not have a manual shutter control, turn off the flash, if available set the exposure control to maximum, if available select a 'night scene' setting, if possible experiment with ASA settings.
Always take two pictures in quick succession, for later comparison, if possible with the help of a friend use two cameras.

Camcorder use in dark/zero light locations
My recommended experimental methods of video recording is as follows-

1, Using a camcorder in normal daylight setting + Blue/UV light
In a dark/low light location select the blue and/or the ultraviolet LED's
This should provide illumination for most camcorders.
Use the various settings of the MODE select switch will provide a range of new experimental procedures.

2, Using a camcorder with a '0 Lux - night vision' setting + Blue/UV light
Turn off the camcorders internal infrared LEDs, select the blue and/or the ultraviolet LED's, personal observation can also be made at this time.
Use the various settings of the MODE select switch will provide a range of new experimental procedures.

3, Using a camcorder with a '0 Lux - night vision' setting + I/RED
Turn off the camcorders internal infrared LEDs
Select only the Infrared LED's on the DL, to make use of the DL's pulsed lighting.
Initially place the MODE switch in position 2 - the Infrared frequency but also experiment with other settings.

The Digital Llighting is new and experimental it allows new opportunities, experimental procedures and potential.
Feedback of results will help with future research and development
