Ever wonder how film works? A recent video from SmarterEveryDay covers this topic in great detail describing how film works.

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.

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? Unfortunately for most of us, the opportunities to photograph a solar eclipse within our lifetimes can be counted on a few fingers. Lunar eclipses are a little easier to plan for but still require some planning.

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).

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.

Wet plate photography is an old technique that still has a number of fans today. But is the process dangerous to the photographer?

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?

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?

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?

Even if you aren’t the type of photographer to be interested in a cicada, let me tell you why this summer’s event will be an amazing photo opportunity. It might just not be what you expect.

In this article, we’ll highlight a shortcoming of the exposure triangle, one that’s more a relic of film days than a modern requirement, and we’ll see how an exposure “V,” with just two legs, might actually afford us more flexibility and control over our images.

Got dust? Yea, thought so. In this article we'll delve into the surprising array of effects that different types of lens and sensor contamination can have on image quality. Some of them kind of cool. None of them good.

Whenever you see one, you’ll point at it, kids love to draw them, and some believe that there is a pot of gold hidden at their end. To me, photographing a rainbow is enough of a gift. Here, you’ll get to know how to increase the chance of seeing a rainbow and how to photograph and edit one.

Should you turn image stabilization off when shooting from a tripod? We’re going to put it to the test and find some interesting results.

So much of photography is about capturing a moment, a place, a person, a glance, a tiny slice of history that is impossible to recreate. When we've only got one shot, we want to make sure we get it right. In this series, we’re examining 11 things that can lead to a loss of image sharpness, what causes them, how to recognize them, and what to do about them!

Ever pulled the images off your camera, zoomed in to 100%, and been a little disappointed with the results? Ever had a hard time figuring out what went wrong? In this series, we’re looking at 11 common causes of poor clarity and how to address each. With a little practice, you’ll be able to glance at an image and know how to fix it.

Ever wonder how Google manages to render everything from bushes and boulders to bridge trusses and skyscrapers in amazing three-dimensional detail? In this article, we’ll find out how. It involves a high-tech lawnmower, a lot of computing power, and thousands of terabytes of data.

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.

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.

Are you worried about AI collecting your facial data from all the pictures you have ever posted or shared? Researchers have now developed a method for hindering facial recognition.

A “camera backpack” has been invented by researchers at the University of Washington, which has been attached to beetles for a point-of-view perspective into their daily life. Described as a “GoPro for beetles,” the camera can be controlled by a smartphone.

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!

A new time-lapse released by NASA showcases 10 years of images of the Sun — 425 million of them, to be exact. Condensed into a time-lapse, the hour-long video consists of one photo of the Sun every day between June 2nd, 2010 and June 2nd, 2020.

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.

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.

If you have ever used dating apps or websites, have you ever considered how your profile picture is perceived by other users looking for a date? Do you go for a quick "selfie" or a professionally shot and edited photo of yourself?

We've seen Elon Musk's company SpaceX in the news consistently since their launch of the Starlink satellites, and with 12,000 set to be released into low earth orbit in the future, it might mean some pretty cool light trails for astro photos. Follow the steps below on how to take photos of the Starlink satellites from your backyard.

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.
