#iphone5s – @vlkphoto on Tumblr

Randomly Pixellated

@vlkphoto / vlkphoto.tumblr.com

Like most people, I have taken thousands of pics over the years. And just like most people even I have barely looked at them myself. This is an effort to pare them down to a small subset of interesting ones. So I will put up one a day until I run out of pics, or patience, or Tumblr. ©CC-BY-SA

Foveated render

On the Charles river, Newton, MA.

What is odd about this photo? The exposure time is <1/1000th of a second, so why is it so fuzzy away from the direct center? The answer lies in how CCDs work -- the exposure might be short, but the pixels are still read out by row. So if you were on an unstable platform, say on a kayak rocking on waves, you may think you have already got the shot that you focused on, but the camera is still reading out the sensor as it twists. That's why the center is sharp, and the edges are blurred. This was taken with an iPhone 5s, before the advent of Apple's machine learning powered computational photography algorithms. On a modern iPhone this scene would be sharp everywhere, with a dollop of high dynamic range corrections to bring out the trees on the far shore. But we would have missed out on the foveated rendering of this image.

Technicolor Labrador .. [1 / 3]

The view through an airplane window, somewhere over Labrador at the end of a long transatlantic flight, looking east during sunset.

This is the photo that convinced me to completely overhaul my thinking about what is a "good camera". Look at how much dynamic range is captured here, land that is already in deep dusk, and the reddish pink light from the setting Sun glittering off clouds and haze over the far Atlantic. Until I got this shot, I hadn't believed it was possible to get such a shot. Taken with an iPhone 5s in 2014.
