Photography Science

Photography is built on physics and engineering — and understanding what's actually happening when light hits a sensor, or how a lens bends light to form an image, makes you a better photographer. This section goes beneath the surface of photography to explore the science that underlies the craft: optics, sensor design, color theory, signal processing, and the technology that makes modern cameras possible.

Researchers Create Nano Camera Held Together With Molecular Glue

It is easy to get hung up on the artistic side of photography and forget about how significant the craft is in the sciences. Now, researchers from the University of Cambridge have developed a camera so minuscule that it allows the observation of chemical reactions in real-time. 

Summer Photo Op: The Perseid Meteor Shower

As you’re probably aware from the level of hype in your news feed, the Perseid meteor shower is approaching and you should get outside to see it now! Technically in late July, it is already active in our skies, but the reality is that there is a fairly narrow window of high activity only around the peak time.

A Closer Look at Lens Diffraction

Every lens has a sweet spot, the aperture where the image sharpness is at its best. If the aperture becomes larger, lens errors will become visible. When the aperture is closed, lens diffraction will become visible. In this article, I am going to take a closer look at lens diffraction. 

Looking Ahead to Future Eclipses

While the lunar and annular solar eclipses are fresh in our minds and travel is gradually returning to some semblance of normality, it’s a good idea to begin to think ahead to future eclipse photo opportunities (especially total solar eclipses) in the next few years. Why plan so far ahead?

Eclipse Season, Act II : June's Annular Solar Eclipse

For 2021, the first event of the “eclipse season” is a lunar eclipse on the morning of May 26. The second is an annular solar eclipse on June 10. In an annular eclipse, the Moon appears too small to block the Sun out entirely, so at maximum eclipse, the Sun is visible as a ring (annulus).

 

How the Universe Makes More Powerful Lenses Than Humans Ever Could

Camera technology is incredibly advanced nowadays, but it has nothing on what the universe can do. When scientists want to study objects that are too far away to be seen with human technology, they turn toward a unique phenomenon called gravitational lensing. This neat video will show you what gravitational lensing is and why it is so useful to observing the early universe. 

Why a Two-Sensor Camera Could Be a Fantastic Option

The concept of creating a mirrorless system is very similar in the case of all the camera manufacturers: get rid of the mirror and create a new lens mount closer to the sensor. What if there was another option to do it, arguably a better one? 

Are Liquid Lenses the Future of Photography?

Xiaomi recently teased a liquid lens for their newly announced Mi Mix smartphones. The liquid lens can change shape to alter the focal length and focus to suit a range of applications. Is this the future of lens technology? 

When Will Curved Sensors Transform the Camera Industry?

Curved sensors will solve some of the challenges posed by the laws of physics that manufacturers battle with when designing lenses, but when is this new technology going to bring about dramatic changes to the world of photography? 

Capturing the Magic Moment: All You Need to Know About Photographing Rainbows

This Photo Took Over 11 Days to Expose

As photographers, we generally think of long exposures as being on the order of a few minutes, maybe a few hours if you get deep into astrophotography. This exposure took far longer than that, however; in fact, it took over a week to gather enough light for the final image. 

When White Balance Adjustments Go Wrong

One of the easiest and most beloved methods of color correction is a simple swipe of the white balance temperature slider. It can change the whole tenor of a scene. There are limits to what it can do, however. 

Developing Medium Format Film With Coffee

Developing your own rolls of film has been popular ever since it was necessary and is something all photographers should try at least once. In this video, that's exactly what happens, but using coffee to do so! 

Ever Wonder Why Images Shot at f/22 Are Softer Than f/8?

You may have noticed that as you stop down your lens, your images become sharper at first, but after a certain point, they actually become softer. Here is why no matter what lens you use, eventually, you will experience softness issues as you use narrower apertures.  

Beneath the Surface: The First Time-Lapse to Record Coral Bleaching

Scientists are constantly capturing the devastating effects of environmental decline all over the world. However, doing so underwater has always proven to be a challenge. In the latest documentary binge watch, a team has successfully shown just how the world below the surface is declining at an advanced rate.

Scientists at the Rijksmuseum in the Netherlands have stitched together 528 photographs of one of Rembrandt’s most famous works to create an image that weighs in just shy of 45 gigapixels. You can now visit their website to zoom in far enough to see beyond even the brushstrokes. 

You can click here to see the image and be prepared for a lot of zooming.

How Do Scientists Actually Create Images of the Coronavirus?

The coronavirus has caused a massive pandemic across the world, and yet, the virus itself, like any, is absolutely tiny, with a diameter of about 120 nanometers (or about .000004724 inches). It is so small, in fact, that traditional imaging techniques cannot resolve it. So, how do scientists create crucial images of the virus to better understand it and lead the fight against it?

Some astronomers and observatories are complaining that satellites sent into low earth orbit by private companies to provide global internet and other services will impact night sky observation and ruin astrophotography. 

How Does Autofocus Actually Work?

It's the unsung hero of your photos, and it's always been improving. It's that little switch on the lens. We've become accustomed to AF, and for good reason. It works, and it works very well.  

Diffraction: A Concept Every Photographer Should Understand

Diffraction is something that can rob your images of sharpness, and as such, it is important to have a functional understanding of what it is and how to avoid it. This excellent video explains what diffraction is and how it varies based on different parameters.

Plan Your Meteor Shower Photography From Your Smartphone

Experienced night sky shooters know that some of the most challenging targets are meteors. While meteor showers, which happen several times a year, will make capturing the elusive meteors easier because there are more of them, you can still point a camera to the sky with a 30 minute exposure and get nothing. Then, suddenly, a meteor can appear where you weren't pointing.

Rules: Love Them, Leave Them, or Break Them Just on Principle?

One of the interesting trends in the comments on a previous article on the rule of thirds was a reaction not just to that rule specifically, but to “rules” more generally. That got me thinking a bit. What are “rules”? Where do they come from? Is breaking them an act of rebellion; or one of self-destruction? 

Art, Ethics, and the Power of a Good Story

Many interesting ethical issues arise across the photographic genres from the perspective of the photographer, their subjects, and their audience. This video on the broader subject of art and ethics, generally, presents a number of questions and thought experiments designed to get us thinking about the roles that art and ethics play in our lives.
