    In a 1995 interview, the late Steve Jobs claimed that the secret to his and Apple’s success was talent. “We’ve gone to exceptional lengths to hire the best people,” he said, believing that the talented resource was twenty-five times more valuable than an average alternative. For Microsoft founder Bill Gates, the multiple was even higher:A great lathe operator commands several times the wage of an average lathe operator, but a great writer of software code is worth 10,000 times the price of an average software writer.While the actual number might be up for debate, the importance of technical talent is not. The most successful companies today are those that understand the strategic role that developers will play in their success or failure. Not just successful technology companies – virtually every company today needs a developer strategy. There’s a reason that ESPN and Sears have rolled out API programs, that companies are being bought not for their products but their people. The reason is that developers are the most valuable resource in business.How did we get here? How did developers become the most important constituency in business seemingly overnight? The New Kingmakers explores the rise of the developer class, its implications and provides suggestions for navigating the new developer-centric landscape.

    As almost every photographer knows, the word -photograph- has its roots in two Greek words that, together, mean -drawing with light.- But what is less commonly acknowledged and understood is the role that shadow plays in creating striking, expressive imagery, especially in portraiture. It is through deft, nuanced use of both light and shadow that you can move beyond shooting simply ordinary, competent headshots into the realm of creating dramatic portraiture that can so powerfully convey a subject's inner essence, communicate a personal narrative, and express your photographic vision. In The Dramatic Portrait: The Art of Crafting Light and Shadow, Chris Knight addresses portraiture with a unique approach to both light and shadow that allows you to improve and elevate your own portraiture. He begins with the history of portraiture, from the early work of Egyptians and Greeks to the sublime treatment of light and subject by artists such as Caravaggio, Rembrandt, and Vermeer. Chris then dives into a deep, hands-on exploration of light, shadow, and portraiture, offering numerous lessons and takeaways. He covers: - The qualities of light: hard, soft, and the spectrum in between- The relationships between light, subject, and background, and how to control them- Lighting patterns such as Paramount, Rembrandt, loop, and split- Lighting ratios and how they affect contrast in your image- Equipment: from big and small modifiers to grids, snoots, barn doors, flags, and gels- Multiple setups for portrait shoots, including those that utilize one, two, and three lights- How color contributes to drama and mood, eliciting an emotional response from the viewer- How to approach styling your portrait, from wardrobe to background- The post-processing workflow, including developing the RAW file, maximizing contrast, color grading, retouching, and dodging and burning for heightened drama and effect- How all of these elements culminate to help you define your personal style and create your own narrative
