Manipulated Photographs, Manipulated Memories

memories

Photo manipulation is nearly as old, if not as old, as photography itself. It has been used in state propaganda, to unify nations, for aesthetic and creative expression, to generate fear, and the list goes on and on.

As technology advances, altering photographic images has become quite easy. This begs the question: do the images we see convey accurate information?

Slow-Speed Photography: Pitch Tar Drop Caught on Camera After 69-Year Wait

There doesn’t seem to be any shortage of high-speed cameras out there, doing work to slow down footage of fast moving objects enough for us to study what’s happening in that short, short time frame. But what about using a camera to capture what could potentially be the slowest moving substance of all time? Yep — someone’s doing it.

Beautiful Photo Collage of the Sun Shows Different Wavelengths of Light

Our sun can look very different in photographs depending on the wavelength of light you’re trying to capture. Some photographs show the sun as a glowing white ball, while others capture hotter areas in a cold blue color. NASA recently took a collection of sun photos shot at different wavelengths and combined them into the beautiful photo collage seen above (here’s a higher-res version).

Are you ready for this? An international team of researchers have developed the world’s first telescopic contact lens — a 1.17mm thick pair of contact lenses that, when you want them to, will magnify your vision by 2.8x. Read more…

That Photon Hitting Your Camera Sensor Took Thousands of Years to Arrive

sensorlight

How long does it take for a photon from the Sun to reach your camera sensor (or film) and help form a photograph? If you answered “8 minutes,” you’d be kind of right, and but also kind of wrong. An answer that’s more correct is “at least tens of thousands of years.”

If Optimus Prime ever decided to retire from saving Earth and take up photography as a hobby, this is one camera he might consider using. Called the Hyper Suprime-Cam, it’s a 870-megapixel ultra-wide-field camera that stands 3 meters (~10 feet) high and weighs in at 3 tons. The comparison illustration above shows what the camera looks like next to a 5.2-foot-tall girl.

A Mathematical Look at Focal Length and Crop Factor

focallengthmath

I’m hoping this post can explain a lot of the confusion beginning photographers have about focal length and crop factors. Some understanding of basic geometry is required for you to fully grasp this post. Also note that I’ll be rounding the math decently well. Just run through the calculations if you want exact answers.
