I’m a Mac user, and an independent author. I’ve published six eBooks, all of which are technical in nature. What does that mean? It means that my books have illustrations, photographs, and other graphic content that needs to be positioned on the page properly. You know, layout and design. In 2006, when I released my first eBook, The Photographer’s Guide to Capture NX, the iPad was at most just a gleam in Steve Jobs’ eye. I used the best format available at the time, Adobe’s PDF standard. Now while PDF is a great format for files with specific layout and design, it doesn’t transfer well to the future of eBooks: interactive content. Moreover, the only way to distribute eBook content in the mainstream commercial channels (Kindle, Nook, Apple iBooks) was to convert it to some form of ePub format.

I have this blog to share my thoughts, knowledge and opinions. Don’t let content like mine be subjected to the whims of corporate (or government) censorship. Defend the Web. Please sign this petition against two potentially catastrophic bills, SOPA and PIPA. Despite their catchy names and “good intentions” of stopping online piracy, these bills would give unprecedented, unilateral power for corporations or the government to “shoot first, ask questions later.”
Look, I’m totally against online piracy. In fact, I’ve had to write my share of cease and desist (DMCA) letters to various bit-torrent sites illegally sharing my eBooks and videos. But say I were to post a link in this blog that someone, somewhere, decided infringed on copyrighted material. Instead of getting a notification to remove the content, they could instead just shut my site down. Poof. And that’s what this is about. It’s not about protecting piracy. It’s about protecting liberty.
In the early years of digital photography, it seemed like there were two simultaneous battles between manufacturers: the “megapixel war” and the “noise war.” It seemed like everyone was rushing to put more pixels on their sensors, and also make them produce clean images at what were unheard of ISO settings for film users (if you used film, ISO 1000 was very grainy).
All of these battles led to better and better sensor technology, and the production of larger sensors for digital cameras. At any megapixel resolution, a larger sensor means larger photosites, and in-turn, a cleaner image at high ISOs. With the release of the Nikon D3, and later D3s, a usable ISO 12,800 was a real possibility. Continue reading In today’s photography, does noise even matter?
