Software and Photography


Once upon a time, a good photograph was a combo of the skill of the photographer + the lens quality. And while those factors still matter, there’s now a 3rd parameter in that equation, writes Ben Evans:
“Most of the advances in smartphone cameras now happen in software.”
The software helps “get a better picture out of the raw data coming from the hardware”.

A while back, Apple launched “a dual-lens system but uses software to assemble that data into a single refocused image”. And today, both Google and Apple offer the capability with a single-lens system! Don’t ask me how, but machine learning algorithms are able to do it… Welcome to the age where:
“The technical quality of the picture you see gets better because of new software as much as because of new hardware.”

For example, today’s portrait mode in smartphones does “face detection as well as depth mapping to work out what to focus on”. Exposure, color-balance, you name it: the software can deal with it:
“When you take a photo on a ski slope it will come out perfectly exposed and colour-balanced because the camera knows this is snow and adjusts correctly.”
And is the day far, muses Evans, when “it will know which of the faces in the frame is your child and set the focus on them”?!

Machine learning algorithms already classify every pic based on what it contains. Want to find a pic? Just ask the phone!
“You can ask for ‘all pictures of my son at the beach’ or ‘every picture of a dog’.”

Whatever next?!

Why we Deceive Ourselves

In their book, The Elephant in the Brain , the authors describe this weird aspect of deception that we practice: deceiving ourselves! That is so weird: “If our minds contain maps of our worlds, what good comes from having an inaccurate version of these maps?” The Sigmund Freud school of thought treats self-deception as a defense mechanism, “a way for the ego to protect itself”. The mind seeks to protect itself from anxiety and other negative emotions. Many object to this reasoning: since accurate information is so critical to our survival, surely distorting information would be dangerous. Wouldn’t the goal of protecting our self-esteem have been better achieved by making the brain’s self-esteem mechanism stronger instead? The new school of thought explains self-deception as “primarily outward-facing, manipulative, and ultimately self-serving”. This is based on Thomas Schelling’s work on game theory: “In a variety of scenarios, limiting or sabotaging yourself is the winn...

Europe #3 - Innsbruck

The last city we visited in Europe was Innsbruck in the Austrian Alps. After the cold and windy experience (at times) of Paris and Netherlands, Innsbruck was a wonderful change – it didn’t feel that cold, it was not windy all of which made it easy to walk around. Something absolutely necessary given how scenic the place is.   Since the hotel check-in time was much later in the day, we left the baggage and went to the Swarovski HQ-cum-museum about an hour by bus from Innsbruck. The crystal exhibits were brilliant – colorful, bright, shiny. Jewellery aside, it was a display of what one can do with crystals. While my wife and daughter loved the jewellery, I liked the superhero themed exhibits of Batman, Spiderman, the Hulk, and Star Wars. We didn’t buy anything there, though we did buy stuff in the Swarovski store in Innsbruck – jewellery, not the superhero stuff.   Innsbruck is a major tourist attraction during the skiing season but now in summer, we saw many groups of ...

The Thrill of the Chase

So many people complain about the difficulty in making decisions while shopping. Do you buy Brand X that gives 20% extra free? Or Brand Y that has 10% off? Or Brand Z that gives something else free with it? Do you buy that flat screen TV today or wait for the sale at Diwali? Now since the customer is king, shouldn’t companies be simplifying pricing choices? Like maybe offering consistently low prices all the time? Not so fast, as the US store, JC Penney discovered to its cost. Turns out that while people do complain about pricing choices, they are irrational. Also, they enjoy the thrill of the chase. Huh? The word “sale” acts like a siren call for many people: it lures them in to make that purchase. Consistently low prices don’t do the same. Besides, if a competitor lowers their prices just one time of the year, and Poof! Suddenly that low price claim becomes suspect in shoppers’ eyes. Then there are those sites that offer coupons: have lunch at Restaurant A on Wedne...
