Can You Even See the Difference Between 1080 and 8K?

YouTuber Matti Haapoja decided to put himself, and his viewers, to the test: can you tell the difference between shots taken in 1080p and those taken in 8K from the Canon EOS R5? He edited several clips back to back in a mix of 1080p and 8K to see if the average person watching on YouTube can tell which is which.

How To Take Photos Like Vivian Maier

Armed with her Rolleiflex, a roll of TRI-X 400 (or Ektachrome) film stock, and her bold character, the late Vivian Maier made herself legendary with her dramatic street photography. Her street portraiture in particular is riveting thanks to the expressions on her subjects. As Frederik Trovatten puts it in this 13-minute video, "she takes the photo she wants to take whether the subject wants to be a part of it or not."

This Guy Prints Color Photos with Dirt

Photographer Calvin Grier is a master of the alternative photography process known as carbon transfer printing, but for the past few months, he has been taking things to a new level. Grier is creating full color photographic prints using dirt.

The $4.5K Fuji XT-1 Forensics Package Doesn’t Really Create UV Photos

UV photography has many obstacles. Ultraviolet light, or light from 200nm – 400nm in wavelength, is notoriously difficult to image with normal camera equipment. A normal digital camera will record images in the visible light spectrum, or 400nm – 700nm in wavelength. To unlock sensitivity to those shorter wavelengths, a camera has to be physically modified to allow passage of light below 400nm.

Are You Still Chasing ‘Perfect’ Color?

It's my belief that color is actually one of the most subjective elements that we as humans all understand, yet we actually have no real way of enforcing or translating it to one another.

Bill Biggart: The Hero Photographer Who Died Capturing 9/11

September 11, 2001, was a sunny Tuesday morning. Bill Biggart and his wife Wendy Doremus were walking their dogs in downtown Manhattan. At about 8:45 a.m., the couple noticed clouds of grey smoke forming against the clear blue New York City skyline. A passing taxi driver informed the couple that an airplane had crashed into the World Trade Center.

Canon R5 and R6: Comparing the File Formats (RAW, CRAW, JPEG, and HEIF)

In my last article, I shot images with both the Canon R5 and Canon R6 to compare the ISO performance of both cameras. As always, this lead to a lot of comments, emails, and DMs asking me if I could also compare the different file formats of these cameras. While I still have both these cameras on loan from Canon, I decided that now would be a good time to tests these parameters for all of you (and me too).

A Primer on Collecting Photo Books

Revisiting my photography book collection has brought me much enjoyment during the lockdown. A dozen years ago, as the business of photography was good, I used the disposable income to start collecting. In this article, I summarize what I wished I knew back then, not only as a photographer and book collector but also from the perspective of a former art gallery owner and current publisher.

This Dead $10,000 Camera Shows the Danger of Salt Water

LensRentals recently got back a $10,000 Fujinon GFX100 medium format mirrorless camera from a customer who used it in dive housing and reported that it "suddenly died for no reason." After Fuji declared repair impossible and insurance claims were paid, LensRentals decided to take the camera apart and look inside.

The Problem with Using Large Format Lenses on a Digital Camera

Large format photography still enjoys the status of a noble branch in image-making. Legendary names like Planar, Dagor, Heliar, Symmar, and Angulon -- to mention just a few milestones in lens’ history -- bear an almost supernatural aura of excellence.

What Camera Sensor Size Equivalence is All About

Today we are taking a look at equivalency. Not equivalent exposure, equivalency. What the heck is that? Equivalency is a very, very complicated subject matter, but one people have been screaming about because of the last format comparison we did.

These are the World’s First Photos of Lightning

In the 1880s, photographer William Jennings set out to prove that lightning was a far more varied and volatile thing than a simple zig zag in the sky. After some trial and error, he ultimately succeeded, capturing what is often shared online as "the world's first photograph of lightning."

Canon Lens Acronyms and What They Mean

If you've ever been Canon lens shopping, you've probably had to take a minute (or five) to figure out what the name of the lens actually means. With a string of seemingly random letters and numbers, these abbreviations have baffled photographers, beginners, and some professionals alike, for as long as they have been around.

The Business of Deepfakes, Cheapfakes, and Misleading Manipulated Media

Some speculate that overall fake news could cost the economy $39 billion a year. Quite a market to grab for a savvy tech startup, even at 1%! But while fake news and in particular deep fakes have been accused of wreaking havoc on minds and economy, there is surprisingly only a minimal amount of companies offering tools to combat them.

How Ansel Adams Revolutionized Landscape Photography

Billions of photos are being snapped and shared on the Internet every day. There are more cameras than people in the world nowadays. Photography is something we take for granted; something we can easily do whenever we want. But it wasn’t always like this.

Using Water to Explain the Properties of Light and the Exposure Triangle

Photographer Robert Hall recently released a simple-yet-brilliant explainer that uses water to illustrate the properties of light and explain a few concepts that frequently confuse beginners, including: what is a "stop" of light, how do you use the exposure triangle, and how do various flashes and flash modifiers affect your image.
