Changed to "daylight" time Sunday? Don't forget to reset your camera's clock

Clock in Musee d'Orsay in Paris, FranceOn Sunday, March 10, 2019, most of the U.S. switched to Daylight time from Standard time. Not all of the U.S. makes the change. Arizona, except for the Navajo Nation, Hawaii, American Samoa, Guam, Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands don't switch to Daylight time in the spring nor back to Standard time in the fall. Their clocks are always set to Standard time.

If you travel internationally, it's important to be aware that the Daylight/Standard time change doesn't universally occur across the globe. More than 100 countries never change to Daylight time and more than a few countries switch between the two on different dates than other countries.

The new lithium-ion battery ban on passenger aircraft as cargo

Nikon camera batteryLithium based batteries on commercial passenger aircraft have been regulated since 2008. That year, the U.S. Department of Transportation (US DOT) banned spare lithium based batteries from passengers' checked luggage.

At the end of last month, the US DOT formalized what U.S. based commercial passenger air carriers already had been doing. They banned the “transport of lithium-ion cells or batteries as cargo on passenger aircraft.” ICAO (International Civil Aviation Organization) had called for the ban since February, 2016.

Study concludes smoking can diminish photographers' color vision acuity

Color Acuity - RGB Color CircleThe deadly health effects of tobacco were made known in 1964, when Luther L. Terry, M.D., then Surgeon General of the U.S., released the first report of the Surgeon General's Advisory Committee on Smoking and Health. From that report and subsequent ones, we know that smokers are more likely than non-smokers to develop heart disease, stroke, lung cancer and a myriad of other serious diseases.

According to the CDC, the statistics about smokers contracting life threatening diseases compared to non-smokers are startling.
  • Smokers are more likely to contract coronary heart disease by 200%-400%.
  • Smokers are more likely to experience a stroke by 200%-400%.
  • Smokers are more likely to die from Chronic Obstructive Pulmonary Disease (COPD) by 1,200%-1,300%.
  • Male smokers are more likely to develop lung cancer by 2,500%.
  • Female smokers are more likely to develop lung cancer by 2,570%.
Cigarette smoke is extremely toxic. It contains about 4,000 active compounds, including tar, polycyclic aromatic hydrocarbons, formaldehyde, carbon monoxide, and heavy metals.

Super Blood Moon - Image courtesy of NASAOn Monday, January 21, 2019 from 0236 GMT until 0748 GMT there will be a total lunar eclipse. For those in the U.S., I'll translate. The lunar eclipse will run from Sunday, January 20, 2019 at 9:30pm EST until Monday, January 21, 2019 at 2:45am EST.

In North and South America, the entire eclipse will be visible from the penumbral, to partial, to full eclipse and back again. Other parts of the world will be able to see all or much of the lunar eclipse, though much of Asia and Oceania will miss it entirely.

Happy New Year 2019 - Change your camera's copyright notice!

Copyright? Happy New Year.

It's January 1st, time to reset the copyright notice in your camera to reflect the new year. Make sure your 2019 images have the correct information.

Most digital cameras today can automatically insert your copyright notice into the metadata of every image you make as they are stored. By the time you read this article, each of my cameras will have been reset so that they will insert the following copyright and use statement into every image I make with them:
“Copyright © 2019 NSL Photography. All Rights Reserved.”
If you haven't been inserting your copyright notice in your images to protect them, I suggest you consider beginning the practice today.
