radiation
ultraviolet or infrared wavelengths of light and heat energy used for curing an ink film or exposing a photostencil.
Irradiation
The physical structure of the emulsion and the distribution of the silver halide grains cause rays of light to be scattered as they travel through the emulsion.

ULTRAVIOLET RADIATION - (UV) - Ultraviolet light is invisible to the human eye, but can be seen by bees and butterflies. Most photographic films are sensitive to this electromagnetic radiation.
Main article: Radiation pressure
Light pushes on objects in its way, just as the wind would do. This pressure is most easily explainable in particle theory: photons hit and transfer their momentum.
Thermal Radiation Radiation emitted by any object with a temperature greater than absolute zero. A thermal spectrum occurs because some of the heat energy of the object is converted into photons.
Electromagnetic radiation emanating from light sources or reflected from non-radiating objects. Perceived by our eyes and processed in the brain.
The culprit is UV radiation, which is outside the range of visible light but still can affect photographic images by lowering their overall contrast. Don't despair. You can overcome the problem by using a UV filter.
Light-sensitive emulsions are sensitive to all wavelengths of ultraviolet radiation. For all practical purposes, the general classes of emulsions are considered insensitive to the shorter wavelengths of ultraviolet (UV) radiation.
Our eyes are not sensitive to all wavelengths of electromagnetic radiation. In fact, our human eyes are only sensitive to a very small band of wavelengths. We can see wavelengths from about 380nm to 700nm.
Technically, it explained as a piece of material which restricts the transmission of radiation. Generally coloured to absorb light of certain colours. Can be used over light sources or over the camera lens.
High altitude is major reason for high UV radiation, but not necessarily for blue casts (I mean real overall cast and not apparent shadow blue). I have done quite a lot of photos at appx. 3000-4500 m. with no UV filter and without blue casts.
Contrary to popular thought, near infrared photography does not allow the recording of thermal radiation (heat). Far-infrared thermal imaging requires more specialized equipment, and is not the subject of this tutorial.
Mercury vapor in the tube emits ultraviolet radiation that is converted to visible radiation by the fluorescent coating.
Note also that "infrared light" is technically considered a misnomer by many people, since light is by definition electromagnetic radiation that's visible to human eyes.
Light is electromagnetic radiation visible to the human eye. It consists of different wavelengths, which are perceived as different colours. Very long wavelengths are perceived as red, and very short ones as violet.
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light. It is named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet.
Infrared film: A film sensitive to infrared radiation. Used for experimental photography.
IR setting: Special focus setting, marked in red, for infrared photography. Infrared radiation are focused further from the lens than visible light.
Subtractive color mixing uses light filters to remove the unnecessary colors present in the incoming radiation. For most purposes white or quasi-white light is used, as it contains all the colors of the spectrum.
It is included, but in fact the result can't be properly simulated for obvious reasons - the filter is just blocking invisible UV radiation...
From the other hand filters such 87C are Infra Red filters - they are transparent only for IR light.
Another method to achieve dominance is through convergence or radiation or lines. The eye tends to follow these lines to the point where they converge.
Veins on this leaf converge at a single point making it the dominant element in the image.
Infrared Film: A black and white or colour film that is sensitive to infrared radiation, which is invisible to the human eye.

Luminescence
The visible light produced from a surface submitted to invisible radiation such as UV, X rays and son on. Unlike fluorescent light it continues to be emitted after the existing source is removed, gradually fading away.
Actinometry is the measurement of the intensity of radiation - particularly light - and especially by measuring the speed of a photo-chemical reaction.
The ultra violet ray. This is beyond the visible spectrum i.e. it's invisible electromagnetic radiation of the sunlight. UV lenses is very expensive, only Nikon has a offering in its Nikkor lens line.

As for the International Space Station, it's been all-digital from the moment a permanent crew set up home in 2000; film stored in space for months inevitably fogs from radiation exposure.
Laser: The acronym for light amplification by stimulated emission by radiation. The laser is an intense light beam with a very narrow band width that can produce images by electronic impulses.
This includes irradiating all envelopes with a very high dose of radiation. This can cause damage to the paperwork (It burns!) and the CD-ROM (They melt!). Send your submission in a box.

Filter which may be used to absorb UV radiation, to reduce its effect.

You can use this filter to simulate different methods of capturing the infrared portion of the electromagnetic radiation spectrum and the effects produced by films that can capture those wavelengths.
For example, medical researchers use ultraviolet light to track radiation or particular cell growth; similarly, crime scene investigators use ultraviolet photography to capture images of blood or semen splatters.
Herbst also recommends wearing a wide-brimmed hat. Whether it's summer or winter, continued exposure to the sun can be harmful. A wide-brimmed hat helps protect your
eyes and skin from harmful UV radiation.
Also, CNTs are promising for supporting materials of catalysts in fuel cells, hydrogen storage, wiring of next-generation ICs, heat radiation, and electronic devices such as field effect transistors.
Even with no exposure whatsoever, you'll find noise generated from ambient radiation.
Others are very expensive and used primarily by law enforcement, the military, naturalists and scientists. The technologies in use include amplifying existing light, capturing thermal radiation, and capturing infrared light.
