What the Naked Eye Sees in the Night Sky Compared to What the Camera Can Capture

EYECAMERACOMPARE

The Internet is teeming with photographs and videos of the starry night sky that dazzle the eyes and tickle the imagination, but have you ever wondered how the imagery compares to what photographer’s naked eye actually saw while the camera was taking a picture?

Photographer inefekt69 recently decided to answer that question by creating the photos above. On the left is what the human eye could see in the dark, outdoor field, and on the right is the photo he shared online.

Why Complaining About Photos Being Photoshopped Makes No Sense (To Me)

Every day about 200 million photographs get uploaded to Facebook. That’s almost double the number of all the books that have ever been published in human history. And that’s just Facebook, I’m not even mentioning Instagram, Snapchat, or just the photos everybody takes and doesn’t even post online.

While taking all those pictures, most people don’t really think about what they’re actually doing, or how the process works. But if they did think about it, I guess their reasoning for that process would be somewhat like this…

Did you know that 90% of the cells in (or on) the human body are bacteria and other microorganisms? Have you ever thought about how many bacteria live on your DSLR camera? Chicago Tribute staff photographer Alex Garcia recently dove into this second question while visiting the Argonne National Laboratory outside Chicago.

The Camera Versus the Human Eye

This article started after I followed an online discussion about whether a 35mm or a 50mm lens on a full frame camera gives the equivalent field of view to normal human vision. This particular discussion immediately delved into the optical physics of the eye as a camera and lens — an understandable comparison since the eye consists of a front element (the cornea), an aperture ring (the iris and pupil), a lens, and a sensor (the retina).

Despite all the impressive mathematics thrown back and forth regarding the optical physics of the eyeball, the discussion didn’t quite seem to make sense logically, so I did a lot of reading of my own on the topic.

Male and Female Photographers See the World Differently

If you think male and female photographers sometimes have very different styles, the reason might go beyond their tastes and approaches to shooting. Men and women see the world differently — literally. A new study by vision researchers have found that the two genders have different ways of collecting visual information.

According to the findings, men are more sensitive to moving objects and seeing small details, while women tend to be sharper in seeing color changes.

Scientists Shoot a 281-Gigapixel Photo of a Tiny 1.5mm Embryo

Gigapixel images are usually used to capture tiny details in expansive scenes, but scientists in the Netherlands recently created one that shows microscopic details in a tiny subject. Using a technique called virtual nanoscopy (a new relative of microscopy?), the researchers created a massive 281-gigapixel image of a 1.5-millimeter-long zebrafish embryo.
