Last week, Canon confirmed that they had stopped using the contentious terms 'master' and 'slave' in their flashes and triggers three years ago, but it looks like Nikon beat them to the bunch... by a lot. In a new statement, Nikon claims they stopped using the term "slave" in the early 2000s because of "the term's negative context."
As protests against systemic racism swept the globe this year, there have been calls by some photographers for ending the use of the terms "master" and "slave" in the industry. Now Canon has come forward as the first camera company to officially stop using those terms on its camera gear.
There are unfortunately times when technology just lets us down. It’s not always because it inevitably breaks either: sometimes it is simply because every piece of gear has its strengths and weaknesses, and flash triggers are no exception.
The flash built into your iOS device isn't anything to write home about. If you want something more capable, the general approach is to attach something more powerful, like a Kick Light or Manfrotto's KLYP flash. But there is another way to do it.
What if you could slave other phone's flashes? Something like it turned up in an Apple patent a while back, but a developer beat Apple to the punch by designing a camera app that does just that.
A rather interesting submission by Apple to the United States Patent and Trademark office shows potential plans for a synchronized flash system by connecting iOS devices, which will allow a primary camera to snap an image of a subject whilst being lit by another iPhone, as an example.
Jonathan Dandrow believes that traffic enforcement cameras are "dangerous, invasive, error-prone, and unconstitutional," so he decided to find a way to turn camera technology against those cameras. He ended up creating the noPhoto, a high-tech license plate frame that makes it impossible for a red light or speed trap camera to snap a useable photograph of your plate.
