We found that about 83% of the world’s population and more than 99% of the U.S. and European populations live under light-polluted skies (that is, where artificial sky brightness at the zenith is >14 µcd/m2). Due to light pollution, the Milky Way is not visible to more than one-third of humanity, including 60% of Europeans and nearly 80% of North Americans. Moreover, 23% of the world’s land surfaces between 75°N and 60°S, 88% of Europe, and almost half of the United States experience light-polluted nights.Read the entire study at ScienceAdvances.com.
The countries with the populations least affected by light pollution are Chad, Central African Republic, and Madagascar, with more than three-quarters of their inhabitants living under pristine sky conditions. The countries and territories with the largest nonpolluted areas are Greenland (only 0.12% of its area does not have pristine skies), Central African Republic (0.29%), Niue (0.45%), Somalia (1.2%), and Mauritania (1.4%).
On the other side, the most light-polluted country is Singapore, where the entire population lives under skies so bright that the eye cannot fully dark-adapt to night vision. Other populations experiencing this level of light pollution are Kuwait (98%), Qatar (97%), United Arab Emirates (93%), Saudi Arabia (83%), South Korea (66%), Israel (61%), Argentina (58%), Libya (53%), and Trinidad and Tobago (50%); all of these countries have more than half of their inhabitants living under extremely bright skies.
British photographer Mark Lloyd works in the specialised world of sailing and over the last 15 years has won himself a reputation for exceptional action images of all manner of watery pursuits. His latest assignment, to photograph the America’s Cup catamarans as they ‘fly’ across the race course, is being made infinitely easier thanks to the EOS-1D X Mark II, as he explains to CPN Editor David Corfield...See the entire article on CPS website.
I used to consider myself a “natural light” photographer and I got really good at controlling the light that was provided to me to make beautiful portraits. Speedlites were somewhat of a mystery to me for some reason because while using TTL (through-the-lens flash metering), I never knew exactly how much light I was putting on my subject. For some reason, that was important to me, most likely because I learned on manual flash units that had three settings . . . 50 watt seconds, 100 watt seconds and 200 watt seconds. Anyway, once the 600EX-RT was released back in early 2012, a whole new world of lighting control opened up to me. I love these Speedlites for a few reasons:See the entire article on the Canon Digital Learning Center.
I’m absolutely a Speedlite guy because they are so darned reliable and portable.
- I have the reliability of radio transmission from camera to off camera Speedlites.
- TTL automatic flash is very accurate, more so than it’s ever been.
- With this system I had complete control over all units in up to five different groups with the ability of having some flashes in E-TTL and others in manual.
While on a recent trip to ShutterFest, a terrific photography conference in St. Louis each Spring, I taught a class entitled Great light Anywhere, Anytime with Speedlites. The goal of the class was to give students more confidence, something I didn’t have until 2012 when this Speedlite made its debut!
During the class we made some terrific images of our model, Anna Elizabeth Truett, and I’d like to share some of them by walking you through the progression of how the final portrait was created . . . all with Speedlites.
“It’s all a big mess,” that’s how Nikon Europe Ambassador, Joel Marklund, described covering each adrenaline-fuelled moment of the recent nail-biting UEFA Champions League final between Real Madrid and Atletico Madrid.See the entire post on the I AM NIKON Blog.
Setting up on the sidelines, handling his remote cameras, the pressure to send images ‘live’ & using the ethernet, the importance of position and a little creative thinking: Joel shares what it takes to really deliver the signature shots everyone wants.
