You come back from a photoshoot and download your images and start evaluating your work.
You notice dark spots in the same location in every frame.
Now you have to spend countless hours "retouching".
We know that particulate (dust, pollen, and other types of dirt) can stick to the surface of the
image sensor filter. This particulate creates a shadow on
the image sensor array, degrading the image quality (see illustration below).
A common reason for particulate sticking to the image sensor filter is the presence of
electrostatic charges. The electrostatic charges will attract and "hold" onto any particulate that
comes under the influence of its electric field.
The camera’s image sensor filter can possess both positive (+) and negative (-) electrostatic
charges, so it is important that the method used to clean the sensor is capable of neutralizing
both types of charges.
The Solution: While there are many methods available
to the photographer to clean the image sensor filter, only the FireFly
provides a convenient, safe, and effective method to neutralize electrostatic charges
on the components of the mirror box, shutter chamber, and image sensor filter.
The FireFly utilizes a nine-volt battery to 'ionize' the air passing through the body of the Firefly,
producing and delivering both positive (+) and negative (-) air ions to the outlet air stream. This
assures that the static charges are neutralized, allowing the particulate matter to be blown off by
the ionized air stream and flushed out of the camera body.

How does using the FireFly compare to other cleaning methods?
The wet method:
This method requires touching of the delicate imaging sensor filter and potentially damaging the protective filter layer.
The wet method also requires the use of chemicals that can not be carried aboard a commercial aircraft.
Lastly, if not done properly it can leave behind 'swirl' marks.
This method also requires touching, which can scratch the surface.
Brushes must be properly cleaned before each use or they will transfer contaminants to the
surface you are attempting to clean.
Using unfiltered air can transfer rubber and other contaminants from the bulb to
the sensor. Air blowers do not produce the air ions needed to neutralizer static charges,
therefore they can only move the contaminants to a different position of the imaging sensor filter.
Adhesive pads or tape:
Can leave behind a "sticky" residue. As the pad separates from the image sensor filter
it can generate a static charge on the surface, attracting particulate to the cleaned surface.
The new 2nd generation FireFly includes many improvements over the original FireFly.
We have reduced the size and weight, added a new compartment for the battery making it easier to install,
and we added a new 'Timer' circuit that will automatically turn off the FireFly after 15 seconds -
making it possible to use the new FireFly one-handed.
When compared with all the other methods and devices, the NRD FireFly is the clear choice for
