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? 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.

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

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.

11 Ways to Improve the Sharpness of Your Images (Part 4)

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!
