BH = Black Hot
Heat sources are shown in dark, picture is more natural, easier orientation.
BBH = Boost Black Hot
The boost variant of the BH filter optimizes the brightness dynamics. This means that
even less warm objects are displayed better. This facilitates orientation, e.g. in interiors
where often all objects have the same temperature. It is often also more suitable in humid
weather. In boost mode, sharpness is also optimized. In sunshine, this filter may also be
unsuitable.
RB = Rainbow
The Rainbow filter is a technical filter that can be used to assess building insulation. The
color gradient is no longer displayed monochrome as with the previously described filters.
Instead, a false color representation takes place. The course from warm to cold goes over
the colors white, red, yellow, green, blue and black.
RBHC = Rainbow HC
HC filter is similar to the Rainbow filter, except that each color transition still contains a
brightness coding to black. This ensures even stronger contrasts at the transitions from
one color to the other and makes even smaller temperature differences visible. With
this filter, thermally largely homogeneous surfaces such as walls can be particularly well
inspected for changes (e.g. wet areas). However, the orientation and classification of
temperature ranges is hardly possible.
IRON = Iron Bow
Also a technical filter, in which heat sources are displayed in a limited false color range.
The process from warm to cold takes place in the colors white, yellow, orange, purple
and blue. Heat sources are highlighted by an increased contrast. The dynamics of less
warm areas are high.
GLOW = Glowbow
A simple filter, in which heat sources are shown in yellow, colder areas remain red. In
this way, humans and animals are highlighted. If it is used in the forest at night, a
reduced glare effect can be expected, but this is significantly better with the tactical red
filters.
HOT = Hottest
A very popular filter among hunters. Heat sources such as animals and humans are
shown in orange, while all cooler areas remain black and white. This allows a better
orientation. This filter is especially recommended in the second half of the night, when
inanimate objects have cooled down significantly. Otherwise, it may happen that e.g.
trees and larger stones still radiate too much residual heat and thus also appear orange.
