Nature photographers have a new reason to post their geo-tagged images to Instagram, Flickr and other social media platforms.
Researchers at North Carolina State University found a goldmine of information in geo-tagged photos — including the millions of comments on them — of scenic European landscapes to determine people’s opinions of each site. From that information, they created predictive models to help guide land use policy, conservation planning and development decisions.
“Social media offer the possibility of transforming the way researchers collect data on how we perceive and value the environment around us,” says Derek van Berkel, a postdoctoral researcher with NC State’s Center for Geospatial Analytics and co-lead author of the study. “Crowdsourced information provides an exciting alternative to small-scale social surveys, which are expensive and laborious to administer.”
With the Toronto International Film Festival wrapping up this weekend, photography will be in clear focus in T.O. during the next two weeks with three conventions and a new photo exhibit. Combined, these events have something for everyone, from the novice to the professional photographer.
Things kick off on Saturday with Focal Point Ontario at the Holiday Inn International Airport Hotel Sept. 24-26. Tagged “Play, Learn, Grow,” this convention includes workshops:
Claude Brazeau discussing the challenges of working with available light for portraiture,
Robert Nowell talking about how to make a living as a family portrait photographer,
Andre Amyot sharing how to sell your value as a photographer before talking about price with your clients,
Andrew Collett sharing tips on how to market and sell fine art and landscape photography and
Jessica St. Peter providing practical information about search engine optimization.
Researchers have always thought that flat, ultrathin lenses for cameras and other devices were impossible because of the way the full colour spectrum of light must bend through them. To capture an image in a camera, the light must pass through the lenses and bend to converge to a point on the camera sensor, a principle known as refraction. Because different colours bend differently, cameras typically use a stack of multiple curved lenses to focus each colour of light in the spectrum to a single point. Consequently, photographers have had to put up with more cumbersome and heavier curved lenses.
However, University of Utah electrical and computer engineering professor Rajesh Menon and his team have developed a new method of creating optics that are flat and paper thin, yet can still perform the function of bending light to a single point.
Menon and his team discovered a way to design a flat lens that can be 10 times thinner than the width of a human hair or millions of times thinner than a camera lens today. They do it through a principle known as diffraction in which light interacts with microstructures in the lens and bends.
For the vast majority of my photo shoots, my main camera gear consists of a Nikon 5200D with a Nikor 18 to 200 mm VR2 f/3.5-5.6 lens, a Metz 58 AF-2 and various filters and other accessories. Fully loaded (without a laptop or tripod), my camera bag weighs about 10 pounds, which isn’t unusual. However, it is big and heavy enough that I am not going to carry it around with me everywhere I go — to and from work in downtown Ottawa, running errands in my suburb or just out and about walking or on my bike.
Not wanting to miss an opportunity, I bought a Sony Cyber-shot for just such occasions. It fits nicely in my purse or zipped jacket pocket. This 20-megapixel, 30-times optical zoom, f/3.5-6.3, point-and-shoot camera comes in handy when I come across something interesting in my travels. I typically have it on full manual mode, but I can easily switch to shutter or aperture priority.
A new camera filter that lets in three times more light than conventional filters may be three years away, according to University of Utah researchers.
Electrical and Computer Engineering professor Rajesh Menon thought of the idea while developing a new kind of spectrometer, a device that reads the wavelength or frequency of light. He realized that converting spectral information to colour for a spectrometer could be applied to color imaging.
Traditional digital cameras use an electronic sensor that collects the light to make the picture. Over that sensor is a filter designed to allow in only the three primary colors: red, green and blue. With the filter absorbing the orange, yellow, indigo and violet from the colour spectrum, much of the natural light never makes it to the sensor.
Always of interest to us is the National Gallery of Canada’s second floor section dedicated to Prints, Drawings and Photographs. However, from March 24 to September 25, 2016, the Governor General’s Awards in Visual and Media Arts 2016 are on display in the Contemporary Art section on the ground floor.
According to the Governor General’s website, the Awards in Visual and Media Arts were created in 1999 through a partnership of the Canada Council for the Arts and then Governor General, the Right Honourable Roméo LeBlanc (1927-2009). Each laureate receives $25,000 and a bronze medallion.
One of this year’s award recipients is Toronto photographer Edward Butynsky. According to the Canadian Council for the Arts, Burtynsky is one of Canada’s renowned living photographers. His imagery explores the intricate link between industry and nature, combining the elements of industrial activity upon our planet into eloquent, highly expressive visions that find beauty and humanity in the most unlikely of places. Born in St. Catherines, Ont., Burtynsky was drawn early in his career to the Canadian landscape and its resource industries, venturing out into quarries, mines and scrapyards to make large-scale colour photographs, such as the one shown here.
What began as a simple hobby based on my husband Norm’s and my interest for symmetry, design, shapes and layouts developed into a love of an art form. The blending and attraction of opposites has always been a passion of ours. We enjoy creating photographs that show the balance and dual nature of light and shadow.
At Flash Designs Studio, I assist Norm for the majority of his studio projects, working with models and doing theme shoots. My work has been more focused on the great outdoors, not only nature but also architecture.
With a simple Kodak 110, I was the unofficial class photographer in elementary school. Studying journalism in college, I learned the technical aspects of 35 mm photography and put those skills to work at various newspapers and magazines. I’ve become more creative over the years with digital photography, focusing on often overlooked details or taking a different perspective of the seemingly ordinary.
News Flash is designed to provide updates about what is going on in the world of photography, or at least within a short drive of the national capital region. News about photography contests, exhibitions, trends and the latest photographic research will all be covered here. I hope you enjoy my blog.
