NPR’s Radiolab Explores the Subject of Graphic War Photographs

NPR's Radiolab recorded this 30-minute podcast episode titled "Sight Unseen" that explores current issues in conflict photography. We hear war photographer Lynsey Addario share about one particular experience she had with photographing a gravely wounded marine (The images can be see in this slideshow).

Beware: Building Your Own DIY Photo Gear Could Be Patent Infringement

Going a do-it-yourself (DIY) route is popular among photographers who want the benefits of a certain product without having to shell out money in order to buy the actual thing. Here's something you might not have considered though: building a DIY version of something that's patented can actually constitute patent infringement, and sharing those designs with others can land you in even deeper trouble.

This Picture Shows How Aperture, Shutter Speed, and ISO Affect Your Photos

Here's a helpful little infographic that has been floating around the Web. It's a simple look at how the "exposure triangle" -- aperture, shutter speed, and ISO -- affect the outcome of photographs. It's not a complete picture, of course (for example, it doesn't say why you'd ever choose a higher ISO versus a lower one), but it could be a nice illustrated reference for those just starting out in photography.

This is What a 343x Camera Zoom Would Be Like

In addition to the megapixel war, major camera companies are also engaging in a new superzoom war with their latest compact cameras. We recently shared the incredible reach of the 64x zoom on the Canon SX60 and the 83x zoom on the Nikon P900. If we ever somehow get to the point of 343x zooms appearing in cameras, the video above shows what that would be like.

How I Make Money as a Travel Photographer in 2015

Long gone are the days in which being a travel photographer simply meant you shot photography for a certain travel magazine or newspaper. The world isn't that simple anymore, and the level of competition in the photography world has never been higher. But still, I'm fairly sure there are more “travel photographers” on the planet now than there ever were -- just check your Instagram feeds.

The Journey Light Takes from the Sun to Your Camera

Did you know that when you capture a natural light photo, it took those photons about 8.3 minutes to travel from the Sun to your camera? Light feels like it travels quickly for us here on Earth -- so quickly that when we take a picture on our planet, it basically captures things the moment they happen. But in the vast distances of space, it can take light quite a bit of time to get from one place to another.

Man Claims the Sony RX100 III Has Dangerous Levels of Radiation, Is Quickly Shot Down

An Ontario-based vegan who goes by the name Vegetable Police recently released the video above and then began warning photographers with it in online photo forums. He claims that modern digital cameras "output high levels of radiation" and that people should be careful not to have the camera in their hands or against their faces for long periods of time.

This is Why You Shouldn’t Check Your Camera Gear In When Flying

It's often recommended that photographers keep their gear with them when flying rather than checking it in. If the risk of theft and careless baggage handlers aren't enough to deter you, check out the video above. It shows one particular baggage pusher system that's used in an international airport to direct bags onto conveyor belts. As you can see, gentle handling isn't exactly the goal.

The Earliest Known Photos of People Smiling

The following is a collection of some of the earliest known images of people smiling, starting with a pair of soldiers in the Mexican American War in 1847 and up to a group of soldiers near the end of the Civil War.

The Closest Color Photo of Pluto Ever Shot

After a nine year journey towards the outer edge of our solar system, NASA's New Horizons spacecraft has beamed back its first color photo of Pluto and its largest moon Charon. The photo above, captured "just" 71 million miles away from the dwarf planet, is the closest color photo ever made of Pluto.

A Glimpse Into the World of Forensic Photography

Nick Marsh has been a forensic photographer for over two decades over the UK, and he offers his forensic imaging consulting services to the London MET police. He has even written a book about the subject, titled "Forensic Photography: A Practitioner's Guide."

This is What the History of Camera Sales Looks Like with Smartphones Included

A few months ago, we shared a chart showing how sales the camera market have changed between 1947 and 2014. The data shows that after a large spike in the late 2000s, the sales of dedicated cameras have been shrinking by double digit figures each of the following years. Mix in data for smartphone sales, and the chart can shed some more light on the state of the industry.

Behold: The Crazy Capacity of a 512GB Memory Card

If you don't mind shelling out $880 on a single memory card and putting all your eggs in one basket, you can buy Lexar's 512GB CF card (or SanDisk's 512GB SD card for $600). To give you a better idea of just how massive these capacities are, photographer Jared Polin stuck his 512GB card into his Nikon D4s and documented it in the video above.

A Quick Introduction to Shooting with a Tilt-Shift Lens

A while back I got my hands on my first tilt-shift lens. Since then I have carried it with me nearly every day, grocery shopping and subway riding – you name it. It’s quite a special and fascinating piece of glass even having aged 43 years.

How Astrophotography Has Improved Over the Past 135 Years

Want to see how much our ability to photograph space has improved over the past 135 years or so? Just check out the side-by-side comparison above. On the left is a photo of Jupiter from back in 1879 as it appeared in the book "A History of Astronomy in the 19th Century" by Agnes Clerk. On the right is a photo NASA shot in 2014.

Your Camera Lens Can Double as a Lighter in a Pinch

If you're out shooting on a sunny day and suddenly find that you need to start a fire, your lens may be able to do the trick. The video above shows how a photographer named Mohammad recently used his Carl Zeiss 45mm f/2 lens to light his cigarette while out hiking with friends. You could also use this handy little trick to light a fire if you're out camping -- as long as you have some direct sunlight to focus to a point.

Just the Lenses: The Great 200mm Shootout

This 'Just the Lenses' article will take advantage of a Trioptics Imagemaster optical bench to compare lenses from different camera mounts with no camera involved. Why is that different? Because all other forms of testing (DxO, Imatest, or even photography) tests the camera-lens combination.

Check Out the Nikon P900’s Ridiculous 83x Zoom

Earlier this month, we shared a video showing the incredible reach of the Canon SX60, a superzoom compact camera with a 65x lens. If you thought that video was crazy, check out this one featuring the new Nikon P900, which packs an even longer 83x optical zoom lens -- the equivalent of a 24-2000mm lens in 35mm terms.

How Humans Are Teaching Computers To See and Understand Photos

Three year old children can make sense of what they see in photos and describe them to us, but even the most advanced computers have historically had difficulties with that same task. That's quickly changing though, as computer scientists are developing powerful new ways to have computers identify what a photograph is showing.

Iconic Space Photos Are Actually B&W: Here’s How NASA Colorizes Hubble Shots

Did you know that the Hubble Space Telescope is only able to capture black-and-white photos? In order to capture a maximum amount of information in their space photos, NASA captures multiple black-and-white images using different filters in the camera. These images are then combined in post to create the iconic color photographs that you see published by the space agency.

Lighting Fundamentals: High Speed Sync Versus Flash Duration

If you're just getting started in learning how to light your shot with flashes, you may be confused about the terms "high speed sync" and "flash duration." Here's a helpful 6-minute primer in which photographer Daniel Norton explains what these two concepts are, how they differ, and which situations they come in handy for.

The Death Photographers Who Photograph Bodies on the Banks of India’s Holiest River

The Ganges river in India and Bangladesh is the holiest river in Hinduism. Every day, hundreds of dead bodies are brought to the banks of the river by family members and cremated ceremonially on a flaming pyre. On hand to document these rituals for loved ones are death photographers -- young men who make a living by shooting last images of the deceased for a fee.
