On all the smartphones I get my hands on these days there's a n HDR function. Quite often I find that the default is 'Auto' but what difference does it really make? What Is HDR?

Like many of our readers, I am the resident Photoshop expert among my friends and family. Every year, around this time, I am asked to do at least one custom helmet for a friend's fantasy football team.

At a workshop I once taught, an older fellow in the back of the room raised his hand. He said, "I just bought me a new toy and she's a beauty!
