The RF 28-70mm f/2 L: Canon’s Bag of Primes

It’s heavy, expensive, does not have image stabilization, and is impractical for most photographers. It also happens to be one of the best zoom lenses ever made.

Shooting an Automotive Campaign, On Location, Over FaceTime

I recently set out to see what collaborating on an automotive campaign would look like when done virtually. In the words of the always colorful Jeremy Clarkson, “How hard could it be?” TL;DR: Not that hard!

Calculating the Distance of Wildlife in a Telephoto Shot

While enjoying a calm and misty morning at the pier in Malibu, California, I spotted dolphins. After observing them for a while, I noticed that their swimming was synchronized. There was a natural explanation for their circling: a feast had begun, quickly attracting sea lions, pelicans, and seagulls.

Don’t Zoom, Move: Treating Your Zoom Lens as a Series of Primes

We've shared some funny pictures in the past that illustrate how distance, not focal length, changes perspective -- but nothing beats a video walk through. So, in this short video, photographer Mike Browne explains why you should treat your zoom lens as a series of prime lenses, and not the equivalent of getting physically closer to your subject.

How Focal Length and Subject Distance Affect Weight… As Seen with a Cat

We've written a couple of times in the past on how you can achieve drastically different portrait looks by choosing different lens focal lengths and subject distances. Basically, your choice of glass can make a huge impact on what your subject's face looks like... and how much they appear to weigh.

Reddit user Popocuffs wanted to demonstrate this, but instead of using a human subject, he used his cat.

Jumping Spiders’ Eyes May Inspire New Camera Technologies

In a paper published in Science this week, Japanese researchers reported on a discovery that jumping spiders use a method for gauging distance called "image defocus", which no other living organism is known to use. Rather than use focusing and stereoscopic vision like humans or head-wobbling motion parallax like birds, the spiders have two green-detecting layers in their eyes -- one in focus and one not. By comparing the two, the spiders can determine the distance from objects. Scientists discovered that bathing spiders in pure red light "breaks" their distance measuring ability.
