The new High Dynamic Range (HDR) option found since iOS4.1 (the operating system for iPhones, iPods, iPads) onwards can be described as the best of times and the blurst of times.
From what I can figure out, this technology takes three photos in rapid succession, each with different exposure settings – one based on the auto-exposure setting, one underexposed, and one overexposed. The brain inside the iDevice then does some processing and comes up with a mind melded photo that contains the best of all three exposure worlds.
Sounds great!
The catch is if the camera moves a micron in between those three shots, the resulting photo can be a little distorted, and potentially evil. Here is my evidence to back it up:
My son can be naughty at times, but it wasn’t until a HDR photo taken with my iPhone 4, that I realised how truly possessed he is.
Anyways, there are many, many articles on the web about using HDR effectively which I will leave you to go and find. In the meantime, does anyone know of a good exorcist?
