Hey Photographers! Cataracts Are Messing Up Your Color Vision

I had recent cataract surgery on both eyes, about a month apart for each eye. The doctor told me my vision would improve (a good thing). I was having the surgery because it was getting more difficult to see, especially close up. I knew it was time to do something when I realized I couldn't clearly read my weight on my bathroom scale, and I was sitting closer and closer to the computer when editing.

How This Jaw-Dropping Image Was Created

Earlier this year, the scientific community was abuzz when an image of Sagittarius A*, the supermassive black hole at the galactic center of the Milky Way, was released. How did scientists actually create the image, though? It took petabytes of data from a virtual telescope that size of the entire planet. This interesting video will take you behind the scenes to see how it all came together.

NASA's Webb Telescope Delivers its First Images

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. My own experience is that the number of meteors drops off dramatically a day before or after the peak evening.

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.

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
