There
are a few ways to make the camera see infrared. The simplest way is
just to take an infrared filter and place it on the lens, go outside
with a tripod and start taking long exposure pictures.
However, this method is inconvenient, and it will make moving objects blurred.
Permanent Infrared and Full Spectrum Conversion
So
we will do camera conversion. Basically, there are two types of
infrared camera conversion: permanent infrared and full spectrum.
Permanent
infrared is handy when we do not have infrared filters or adapters for
each lens. It also allows us to see the subject through the viewfinder
on a DSLR camera.
Full spectrum conversion facilitates us to try
out new ideas and new filters. Perhaps, one day I want to shoot with a
590nm filter, and another day I want deep black with a 950nm filter.
We need then to buy infrared filters that fit our lens.
In all those two types the filter that blocks UV and IR light will be removed from the sensor.
Different cameras have a different number of those filters. Canon DSLRs and
mirror-less cameras usually have two filters.
Sony mirror-less cameras have one thick filter.
Fujifilm compact cameras have one filter, and Fujifilm mirror-less cameras have two filters.
New
cameras have an ultrasonic sensor cleaning system. Some cameras like
Canon 60D have very clever firmware and detects that this is not the
original glass. It usually gives ERR 70. Disabling the automatic sensor
cleaning system, in this case, makes the camera work properly again.
Infrared Filters
Some
cameras are used for astrophotography. Those have a special filter that
passes Hydrogen Alpha light. The filter for this purpose would be
Astronomic.
There are a few infrared filters. The most
well-known is the 720nm filter, often referred to as “standard”
infrared. It gives a slight grayish image straight from the camera.
