IR-UV photography

 

 

 

 

NEW POSSIBILITIES IN IR and UV PHOTOGRAPHY

Ever since William Herschel discovered infrared radiation in 1800, photography tecnique changed dramatically. Thanks to the digital revolution, we can not only record fantastic photographs of the world around us but also in wavelengths that the human eye is not sensitive at: infrared and ultraviolet. That's why PrimaLuceLab, in collaboration with Nikon, offers a catalog of products (cameras, filters, lenses, etc. ) that allow you to discover the IR and UV photography easily and with guaranteed results.

 

 

 

 

SOME APPLICATIONS OF IR and UV PHOTOGRAPHY:

- Astronomy: some celestial bodies are visible only under in wavelengths. For example cloud formations of Venus show details only when photographed in ultraviolet while star clusters in the interstellar gas nebulae are visible only if photographed in IR. Mars also shows more details of its surface when photographed in infrared.

- Medicine: the IR radiation can penetrate the skin and making it possible to detect problems such as varicose veins. Using UV techniques , it is possible to study the health of the skin and highlight the possible damage caused by too much exposure to ultraviolet rays from the Sun. Even the photograph of the teeth, IR and UV techniques can be used: in infrared enamel appears darker then dentin; in ultraviolet fillings look very dark and are more visible also if in visible they appear white.

- Botany and ecology: IR photography enables you to monitor the health of the plants. A healthy plant reflects the infrared therefore in IR it appear lighter while a sick plant reflects less the IR and will appear darker. The same technique is used to study the concentration of algae or insect infestations.

- Military: infrared technique is used for setting targets. For example, if a target is hidden in the foliage, in the IR it will appear darker than the vegetation that hides it and that appear brighter.

-  Art: many historians use IR photography to detect, below the painting for example, the artist's sketches. Recording details invisible to the eye, IR photography can validate as authentic the paintings.

- Forensic: forensic investigators use IR techniques to detect traces of soil several hours after it has been removed. The same technique is used to detect biological remains such as blood or urine since the IR photo records the difference in temperature between the object and the surrounding environment.

 

 

EXAMPLES OF IR and UV PHOTOGRAPHY:

 

Infrared photography: plants reflect a lot of IR so they appear lighter (upper picture recorded with D5500 FullRange DSLR camera and 77mm IR filter) than the traditional photography in the visible (lower picture recorded with stock Nikon D5500 DSLR camera).

IS IT POSSIBLE TO USE STOCK CAMERAS IN IR and UV PHOTOGRAPHY?

The sensors of DSLR cameras are sensitive also to infrared and ultraviolet wavelengths. But, in order to obtain a true color balance (ie to reproduce colors as seen by the human eye), the camera's designers insert, in front of the sensor, a filter that cuts both the infrared and the ultraviolet. Only some Nikon cameras have a slight residue of infrared sensitivity that allows, with the unmodified stock camera, to record infrared pictures if in front of the lens you install a special IR filter. The sensitivity, however, is so low that the required exposure times are very long (generally longer than 10 seconds at 100ISO). More, in this way it's also excluded the possibility offered by modern cameras to record video (since to record a video at 30 frames per second the shutter speed of each frame should be no more than 1/30 of a second).

We also verified that, if for IR photography you can use the normal camera lens, for the ultraviolet one you must use specially prepared ultraviolet lenses. In fact, most of the treatments used in photo lenses cut ultraviolet. So even if you use the modified camera body and the right filter, you might not be able to photograph the UV.

 

 

 

OUR PRODUCTS IN IR and UV PHOTOGRAPHY

For this reason we have equipped a special area in our laboratory where, starting by the Nikon COOLPIX P788 and D5500 DSLR, we make all the changes necessary to turn them into FullRange cameras, that you can use to take picture both in ultraviolet and infrared. We can therefore offer both complete photographic systems (composed modified camera body, selected lens, filters and adapters) for those looking for a fully functional and guaranteed system, and individual components for those who want to want to create their own custom setup:

 

 

 

 

 

Camera P7800 FullRange: based on Nikon COOLPIX P7800 camera, the P7800 FullRange is sensitive also to infrared and ultraviolet and it's the cheapest solution that lets you record pictures in IR and UV. If you want to know more or order, please contact us!

€ 799,00

 

 

  

 

Recovery filter for P7800 FullRange camera: this filter is screwed, via a special provided adapter, before the lens of the P7800 FullRange camera to get a corrected a color balance for the classic photography. This way you can re-use your P7800 Fullrange camera for normal photography. If you want to know more or order, please contact us!

€ 99,00

 

 

IR-pass filter with adapter for P7800 FullRange camera: this filter is screwed, via a special provided adapter, before the lens of the P7800 FullRange camera and lets you perform infrared photography. If you want to know more or order, please contact us!

€ 115,00

 

 

 

 

- D5500 FullRange only body: based on Nikon D5500 DSLR, the D5500 FullRange camera is sensitive also to infrared and ultraviolet and it's the basic element that lets you record pictures in IR and UV. After replacing the original filter, we perform the focus calibration in order to allow the use of the FullRange camera (and autofocus) with standard Nikon lenses.

- Full Range filter for D5500: FullRange filter replaces the original one in front of the sensor. Designed with the same thickness and dimensions of the original one. If you want to know more or order, please contact us!

€ 95,00

 

 

 

 

- IR-pass 77mm filterthis filter is screwed in front of the lens and it allows you to select only the infrared wavelengths. In this way the D5500 Full Range camera will record only the IR. If you want to know more or order, please contact us!

€ 200,00

 

 

 

 

UV-pass 50mm filter: this filter is screwed in front of the lens and it allows you to select only the ultraviolet wavelengths. In this way the D5500 FullRange camera will record only the UV. Click here for more information and purchase.

€ 269,00

 

 

 

 

- Adapters for front filter: IR and UV filters have a precise size (77mm for IR FILTER, 50mm for UV filter). In order to install them in front of the lens, you need to use these special rings. If you want to know more or order, please contact us!
