High Dynamic Range (HDR) photography is a system for recording more detail in shadows and highlights than standard 24-bit photography is designed to handle. The greater the range between the brightest and darkest points in a photo, the more it can benefit from HDR.
In October 2014, Apple made the iPad Air thinner and gave it a more powerful processor, Apple’s A8X chip – the same chip found in the iPhone 6 and 6 Plus. This was also the first time an iPad was available in gold.
On October 22, 2013, Apple introduced the first 64-bit iPads, including a thinner, lighter version of the 9.7″ model. The iPad Air runs a 1.3 GHz 64-bit Apple A7 processor nearly twice as powerful as the A6X used in the 4G iPad.
