Your digital camera is equipped with a sensor made of thousand of small
phototransistors, those cells has the property to be a lot more sensitive to infrared
than visible light. That is why manufacturers must add a band pass filter to
stop excess of infrared light. So we can reverse the end result by replacing
this daylight band pass filter by an infrared band pass filter which will stop
excess of daylight and let the infrared get through. The results are
spectaculars.
In that kind of photography, trees and everything that contain chlorophyll
change from green to white. The sky gets very contrasted with their whites
clouds on their dark background. We also can see the difference between by a
cold lightening produced by fluorescent light compared with the more hot
incandescent light
. The white balances choose will make some greats effects from black &
white picture to reddish toned pictures.
To modify a reflex camera.
You will have first to
choose and order the IR filter type from lifepixel.com, which may cost from 175 to 300
dollars depending on model. Then you send me your camera and filter so I
can start the modification on which consist to open the camera, take off
circuitry, remove and disassemble the sensor assembly and replacing it band
pass filter by your IR filter with all precautions to not let dust enter
between the sensor and filter. Sometime, I need to reopen the whole unit to
remove small dust that kept inside. On first check, we will see some white or
black dots, which are not dust but dead pixels. Those dead pixels which were
almost invisible prior the modification, become obvious now because the sensor
now can work on a lot more sensitive light bandwidth.
The fees for replacing the filter are roughly between $ 150.00 to $ 225.00 and
the price of the filter itself. The most advantage with the reflex is the wide
diversity of lens available to use with the camera, however the disadvantage is
that the auto focus is no longer usable because of the IR do not converge as
the visible rays do, but now with the new camera including the ''live view''
mode you still can perform an accurate manual focus. If the live view is not
available on your camera model, you will have to compensate the focus a little
bit closer as we had to do with old lens that had a small red dot with the
letter R beside the index mark.
On this lens below the focus at infinity need to be set aligned to the small red dot for IR picture.

To
modify a point and shoot camera.
Here it is far cheaper
and a bit more practical. You only send the camera on which we will apply the
whole modification for around $ 150.00 to $ 250.00 depending on the model, this
include the IR filter which we cut from a blank at the appropriate size. The most
important advantage is that you keep all auto focus function since the image
sensor and the AF sensor are the same.
