It seems impossible for a new Apple product to launch without the idiots and morons crawling out from their dark shells of ignorance, their subhuman bodies propelled only by the motion of a jerking knee as they regain consciousness for just long enough to write a blog post about some perceived “problem.”
Today’s example: purple fringing.
Apparently these denizens of ignorance have never heard of lens flare. It’s caused when light hits a lens at an oblique angle and bounces around inside the glass. Its result is reduced contrast and colored blobs on the image. There are many software packages which add it in as a special effect.
Coating lens elements with anti-reflective potions can help, but there’s a reason that even lenses from Leica ship with tailor-made lens-hoods: flare is inevitable, and the only real way to avoid it is to move the lens out of the light, or shield it.
So, purple-fringe conspiracy theorists: The iPhone 5’s “problems” are plain old lens flare. Boring, right? And here’s Apple’s new support document explaining it:
A purplish or other colored flare, haze, or spot is imaged from out-of-scene bright light sources during still image or video capture.
Most small cameras, including those in every generation of iPhone, may exhibit some form of flare at the edge of the frame when capturing an image with out-of-scene light sources. This can happen when a light source is positioned at an angle (usually just outside the field of view) so that it causes a reflection off the surfaces inside the camera module and onto the camera sensor. Moving the camera slightly to change the position at which the bright light is entering the lens, or shielding the lens with your hand, should minimize or eliminate the effect. [emphasis added]
Shocking, right? It’a almost as if the purple-fringers not only ignored the evidence but actively avoided it. There really is something about Apple that turns people crazy, huh?
