Of course, if transparent shrimp absorb UV light as a means of protection, they could become visible to predators that have UV-sensitive vision." She added, "We haven't tried observing these shrimp with
infrared film because no animals are known to detect those wavelengths."
To achieve the maximum effect, it isn't enough just to load your camera with
infrared film (and remember always to load and unload this film in complete darkness)--a special filter also needs to be fitted to the lens of the camera.This is because all
infrared films are sensitive to daylight as well as infrared, so if no filter is used, the effect of infrared will be largely obscured by the visible light image rendered on the film.
SFX 200 is particularly coming into its own, given the Kodak decision to withdraw its
infrared film," a company spokesperson says.
Its unexpectedly fiery hues result from the use of a special kind of
infrared film that turns greens to reds.
Infrared film can be difficult to work with, but the results are dramatic--made all the more so when the subjects of the photos are deserted warehouses, abandoned factories, and desolate industrial sites in and around her native Cleveland.
In 1998, he changed to color
infrared film, which requires an orange filter.
She then splashed droplets onto the water and recorded the creatures' reactions with
infrared film. The temporarily blind and deaf gators turned toward and lunged at ripples from a single drop of water, says Soares, now at the California Institute of Technology.
By using color
infrared film in the process, he found that both the healthy and the dense giant salvinia infestations could be distinguished from the other species.
The idea is to see if the unexplained flashes shown on an FBI
infrared film of the siege were caused by shots fired at the burning compound or by ordinary ground clutter.
Like Healey, the National Geographic photographers made an amazing discovery: their
infrared film detected a black, carbon-based line, used by the Maya artists to outline shapes and draw words.
The military involvement in aerial photography led to innovative applications such as the use of
infrared film to spot enemy positions through heavy natural cover and the development of ever-longer lenses and finer-grained films to record greater amounts of detail from higher vantage points.
I like using
infrared film, because it records heat rather than light, so anything that has heat in it--like a tree, or grass or a person--comes out very white and ghost-like.
