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.
For his project titled “Momentum”, London/Madrid-based photographer Alejandro Guijarro spent three years visiting a number of the leading quantum mechanic research institutions of the world and photographed the chalkboards there exactly as he found them. The resulting photographs look like intelligent graffiti drawn by some of the brightest minds in science.
Have you ever wondered how Leica chooses its pricing for its high-end cameras? J Shin has written up a great post over at Leica Rumors that offers a geeky and lengthy explanation of the economics behind the company’s pricing decisions:
Every time there is any kind of a product-related announcement here and elsewhere, there are a number of invariable comments complaining about and/or defending Leica’s price strategy. In making these comments, people make references to various economic and noneconomic reasons why Leicas are priced the way they are. This essay is an attempt to show that, basically, almost everybody is right, at least when it comes to Leica’s profit motives. Rather than nefarious greed, devious psychological warfare, and, as some often mention, Dr. Kaufmann’s ignorance of Leica fandom, Leica prices are basically a function of mathematical inevitability.
