Nature Photography Day - June 15

Next month, we'll be celebrating National Nature Photography Day.

It's occurs on June 15 every year. The original date and day was first created by the North American Nature Photography Association in 2006. It was created to “promote the enjoyment of nature photography and to explain how images are used to advance the cause of conservation and protect plants, wildlife, and landscapes locally and worldwide.”

Celebrating National Nature Photography Day couldn't be easier. Pull out your camera or your smartphone, head outdoors and start making photos. Considering visiting a national, state or local park. Go to a national, state or local wildlife refuge. Enjoy at least one of these wonderful venues on this special day.

In the Greater Philadelphia Region? Join me on the 15^th!

If you're in the Great Philadelphia Region, I've got another way for you to enjoy National Nature Photography Day. Join me at the John Heinz National Wildlife Refuge for my National Nature Photography Day Photowalk. The photowalk is free and open to the public. The walk will start at the Refuge's visitor center at 8am. The walk is over level terrain, but wear comfortable shoes. We'll finish by noon.

We'll be photographing summer birds and other animals, plus have landscape opportunities. Remember that it's not a zoo, so viewing wildlife can be unpredictable at times. There will be known areas where birds typically hang-out, but I'll hope for some surprises too. We'll walk along the Impoundment Pond loop, go to the edge of the freshwater tidal marsh in the Refuge and through other habitats there.

The Heinz Refuge is America's first urban refuge and is located near Philadelphia International Airport.

For up-to-date information about this photowalk follow me on the NSL Photography Facebook Page and on the NSL Photography Twitter Feed.

Beware, selfies can be hazardous to your health

Since March 26, three tourists visiting the Grand Canyon have died in the famous national park. The identities of two of the dead are unknown, as are the full circumstances of their deaths. We know that one fell to his death from the South Rim at Grand Canyon Village.

The third tourist who died was from Hong Kong. He tripped near the Grand Canyon's Skywalk while shooting a selfie at the edge of the rim and fell hundreds of feet to his death.

That death follows numerous, needless selfie deaths that occurred around the globe last year.

Using photography contest judging criteria to help photographers self-assess

Many photographers struggle to create an insightful set of principles to self-assess their work. Getting a critique from trusted photographers is an excellent idea, but without regular in-depth, honest image critiques of their own work, photographers will have a tough time improving and growing.

I offer for consideration, using the criteria photography contest judges use to assess images, as the basis for photographers to develop their own workable, rational approach to self-assessment.

When I began to ask colleagues for assistance, by having them critically assess my work, I found that they typically zeroed into the technical aspects of my images. While there is little doubt the quality of focus, bokeh, color, exposure, lighting, composition, etc. are important, I knew that there were other issues that should be included in any image critique. Over the years I developed my own assessment checklist.

Interestingly to me, many years later, when I began to be invited to be on photography contest juries, I found that my list and the contests' guidelines for judging entries were essentially the same. Therefore, for photographers serious about improving their craft today, rather than struggle to create their own checklist, I suggest using the criteria developed by photographers to judge work in photo contests across the globe.

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

On 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

Lithium 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

The 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.

Eclipse Alert: Total lunar eclipse coming January 20/21, 2019

On 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!

Happy New Year.

It's January 1^st, 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.

What the heck is back button focus & why do I need to use it?

When most people make a photo with their camera, they aim, press the camera's shutter release button, wait for the camera to focus, then press the button the rest of the way. Whammo, the image is made.

While that's easy and direct, if you're using a DSLR (Digital Single Lens Reflex) or MILC (Mirrorless Interchangeable Lens Camera) camera, it may not be the best way to focus and shoot. Until 1989, it was the only way to activate autofocus and make a photo with an SLR (Single Lens Reflex) camera, the film based forbearer of today's DSLR and MILC cameras.

It wasn't until 1985 that autofocus was even available. That year, Minolta, having purchased Leica autofocus technology, released the first commercially successful autofocus SLR, the Maxxum 7000. Minolta configured the Maxxum autofocus system to work as most photographers know it today. Autofocus was activated by pressing the shutter release button.

Four years later, in 1989, Canon introduced back button focus. It removes the autofocus function from the shutter release button and assigns it to a button on the back of the camera. Hence the name, back button focus.
