After wondering why the Imaging Resource (IR) was seeing so few updates recently, a number of people noticed that it seemed to have vanished from the internet as of sometime last Friday, May 5. Had another "OG" photo review website bitten the dust?
Focus breathing is a term that is often used when discussing the features and specs of a camera lens. It is an issue that occurs across a wide range of lenses, and it is one that can negatively affect your photography and videography in certain situations. In this article, we will take a look at what focus breathing is, the situations it affects, and how you can avoid it.
The photographic master Henri Cartier-Bresson made some key observations about photography, translated as “the decisive moment” which is often (incorrectly) characterized as: "capturing an event that is ephemeral and spontaneous, where the image represents the essence of the event itself."
One of the more complex technical topics in photography is something called hyperfocal distance. At first glance, the basic definition of hyperfocal distance seems pretty straightforward: It’s the distance at which you focus your camera lens to get as much of your shot in focus as possible, from the foreground to the horizon.

My name is Sebastiaan de With, and I’m the designer of the iPhone camera app Halide. I recently detailed the camera hardware changes of the iPhone XS vs. the iPhone X, and I wondered why Apple’s keynote focused on changes in camera software rather than the new hardware. After testing the iPhone XS cameras for the last week, I get it.
“Bit depth” is one of those terms we’ve all run into, but very few photographers truly understand. Photoshop offers 8, 16, and 32-bit file formats. Sometimes we see files referred to as being 24 of 48-bit. And our cameras often offer 12 vs 14-bit files (though you might get 16-bit with a medium format camera). What does it all mean, and what really matters?
It’s September, which means another generation of Apple iPhones. This year, the iPhone XS (pronounced “ten ess”) adds a slightly larger sensor plus significantly more computing power via the A12 Bionic Chip to enhance the phone’s image signal processing.
Nikon has understandably made a big deal about launching their new Z-mount alongside the announcement of their new mirrorless cameras, the Z6 and Z7. The Nikon F-mount was originally released 59 years ago and the company has made backward compatibility of the system a brand pillar.
Even though photography is an art form and the final result is considered to be an artistic expression of your thoughts and ideas, there is a strong technical side to all of this. You're using a very advanced technological camera to capture the images and you need to know and understand all sort of technical concepts.
Photography can be confusing. I get it. I am not the sharpest knife in the drawer. Because of this, at times it helps us to actually put some of these theories and myths to the test. One of these myths is the concept of compression and, with it, parallax.

Beauty is in the eye of the beholder, and when it comes to “sunbursts” in photos – those points of light with rays streaking out of them – people often have polarizing views. Optical diffraction is the physical property that causes this effect. The appearance of sunbursts is more technically described as “diffraction spikes,” and it’s caused by the bending (sometimes referred to as spreading) of light around an object like the edges of your camera’s aperture.
The Hasselblad H6D-100c is a 100-megapixel medium format DSLR that costs $33,000 without a lens.
