Ultraviolet-induced fluorescence (UVIF) occurs when molecules in an object are excited (energized) by high-energy ultraviolet wavelengths (from our UV flashlight) and as a result, emit longer wavelengths in the visible portion of the spectrum (red, green, and blue). These emitted longer wavelengths are what we are photographing.
A researcher has used ultraviolet (UV) photography to locate a lost fragment of Biblical text nearly 1,500 years after it was originally written. UV photography equipment has looked beyond layers of text to find a "new" ancient translation of the Gospels.
Hasselblad has announced a set of new lens filters that it says meet the same stringent optical standards and high-quality marks as its lenses. It also launched a brightly colored strap that it bills as "eco-friendly."
UV photography has been used by dermatological laboratories since the era of film photography. This technique was then used by the R&D centers to show the protective properties of dermatological and cosmetic products against UV radiation from the Sun.
Moment has launched a new line of CineClear UV Filters that promise to protect agains sun, dust, scratches, and spills without sacrificing image quality.
Did you know that Scorpions glow when you put them under an ultraviolet light? Ecological artist The Butterfly Babe (Sarah Folts) has shared a video showing a mother scorpion with her young gathered on her back and glowing a bright blue and purple under ultraviolet light.
My name is Pierre-Louis Ferrer, and I am a professional French photographer specialized in photography beyond visible for ten years now, including infrared and ultraviolet techniques. I spend a large part of my free time reading, experiencing, testing, and talking with experts in various domains linked with these techniques.
UV photography has many obstacles. Ultraviolet light, or light from 200nm – 400nm in wavelength, is notoriously difficult to image with normal camera equipment. A normal digital camera will record images in the visible light spectrum, or 400nm – 700nm in wavelength. To unlock sensitivity to those shorter wavelengths, a camera has to be physically modified to allow passage of light below 400nm.
Dropping colored milk into water and photographing the effects is nothing new – these experiments have existed for decades and can yield some very interesting abstract images. The technique can be brought into the “mad scientist” realm by switching gears slightly – using UV flashlights and fluorescing ink, we can make it glow!
We photographers obsess about finding the right light. We understand how to use hard light, when to use soft light, and get excited by directional light. Portrait photographers learn how to control light using flashes and modifiers, and become experts in getting the most from natural light.
For my latest project, titled RAW, I shot a series of UV portraits revealing the true appearance beyond the visible. Composed of twenty photographs divided into ten diptychs, the series illustrates the raw and natural character of the human being, revealed by the technique of ultraviolet photography.
Ultraviolet photography is something that relatively few photographers explore, but it’s a fascinating realm to explore with less of an investment in equipment than most people think.
Using a modified DSLR, ultraviolet light bulbs, and a custom-built massive UV ring flash, Mathieu Stern teamed up with UV photographer Pierre-Louis Ferrer to capture some fascinating portraits and side-by-side video.
Photographers often use UV filters to protect the front element of their lenses, but tests have shown that impacts that shatter your filter will likely to damage your lens as well. Aurora Aperture wants to change that: they've created the world's toughest filters by using Gorilla Glass.
Did you know there's such a thing as UV wool? There's also UV liquid, UV bubbles, and UV holi powder, and in this quick tips video COOPH shows you how you can use all of these to capture some really interesting photography.
Last week, Kenko Tokina USA unveiled the new line of Hoya HD3 lens filters, which promise to be harder than their predecessors while still providing photographers with excellent optical quality.
If you’ve ever dreamed of seeing the world through the eyes of a wild animal or insect, then you happen to be in luck. A team led by scientist Jolyon Troscianko at the University of Exeter in the UK has developed an application that processes RAW image data and then converts it into a result that showcases the way various animals might view their surroundings. Best of all, the software is open source and you can download it today.
Brazilian sports photographer Marcelo Maragni likes to do experimental photography in addition to his "ordinary" sports photography. Earlier this year, he decided that he wanted to try to capture action shots at night with ultraviolet flashes and colorful paint.
It's safe to say photographer Fabian Oefner -- whose many projects have never failed impress us -- has a thing for paint and physics.
Usually this means spraying, spinning and otherwise manipulating it to create colorful, abstract images against a black background. But when Ferrari asked him to capture the essence of their new California T in images, he took his signature art/science hybrid photography to new heights to get the job done.
Artist Tom Leveritt recently ventured out into the world of ultraviolet photography -- or more specifically videography -- to help us take a closer look at the skin we’re in and how sunscreen is a vital tool towards protecting it.
Have you ever come across an artist’s work and thought, "Wow, I would love to work with them!" Well, that is exactly what went through Benjamin Von Wong’s mind after seeing Michael Rosner’s work.
Fast forward two years and Von Wong finally got his wish, creating some beautiful and inspiring untraviolet photographs in the process.
Portland, Maine-based photographer Ben DeHaan has an unique---and slightly disturbing---series of portraits in a project titled "Uncured." Each of the photographs is shown in two forms: one shows what the image originally looked like, and the other is a portrait that's "melting."
High-resolution photography is seemingly where it's at in today's day and age. NASA knows this, and as such, astrophysicists at both the Goddard Space Flight Center (GSFC) in Maryland and Pennsylvania State University have stitched together a remarkable 160-megapixel UV image of the Large and Small Magellanic Clouds -- our two closest neighboring galaxies (less than 200,000 light years away).
Typical photography exists around the visible spectrum (think of the rainbow), but cameras are also able to pick up other wavelengths of radiation. Ultraviolet radiation, as the name suggests, comes after the violet section of the visible spectrum so is not visible to our eyes. However, some animals (birds, for example) are able to see UV.
UV reflectance photography essentially is recording the UV radiation which is reflected back from a UV source. A UV source emits UV radiation, and this is often referred to as UV light. However UV light does not exist, since light is visible and UV is not! UV reflectance is a fairly involved and arduous process without specialized equipment, however the results can be very rewarding.
Ultraviolet fluorescence is a mechanism in which UV radiation excites chemicals in an object and causes them to release visible light. There are many household objects which fluoresce, such as some washing detergents (anything that ‘makes your whites whiter), soda water (it contains a chemical called quinine which makes it taste bitter, and also causes the fluorescence), the dyes found in highlighters, the bacteria found on the face (which cause spots and acne), bodily fluids (including urine) and much more.
UV lens filters are a popular way to protect the front element of lenses from damage, but you should make sure you invest in a high-quality one unless you want to make a huge sacrifice in image quality.
You may have heard that digital cameras can be made sensitive to infrared light by removing the IR filter found inside, but did you now that something similar can be done with the human eye? People who have aphakia, or the absence of the lens on the eye, have reported the ability to see ultraviolet wavelengths. Claude Monet was one such person.
Glow Graffiti is an aerosol can-style light painting tool similar to …
One of the benefits of running a gear rental business is that you have a ton of equipment you can use for random experiments. That's exactly what Roger Cicala, the owner of LensRentals, did with the UV filters he had on hand. One-upping the 19 filter stack we shared a while back, he mounted 50 different UV filters to a Canon 5D Mark II and 300 f/4 lens to see what the resulting images would look like.
Solaroids are unique prints created by photographer Jeff Mclane by exposing large format (4x5 in) Fuji instant film to direct UV light for long periods of time.
