A new iOS app called Polymo ($1.99) will keep your mobile photos organized before you actually shoot them. Add tags while you take pictures and all of your images will be curated automatically.
At CE Week, olloclip, the makers of the original clip-on set of camera lenses for the iPhone, showed off a version for the iPad Air and iPad mini. While some frown upon taking photos with a tablet, olloclip has embraced the phenomenon, even creating a funny and useful pamphlet on the subject entitled "iPad Photography: An Etiquette Guide."
One thing great thing about the iPhone and other iDevices is the ever-improving video recording feature. More and more, smaller design teams and other individual artists are shooting video with iPhones. Of course, shooting on an iPhone or iPad does mean having to shell out extra for accessories to help stabilize your device while shooting. Having witnessed a couple of iPad video shoots myself, I know it can be a process just getting accessory pieces on for a smooth one-take shot. The Horizon app ($1.99) may be a solution to all of that hassle.
HDR stands for High Dynamic Range and it works by capturing three different exposures of the same image and then combining them into a single image. This can be really helpful when your subject includes a large range of lights and darks and you want the details in the darker parts of the photo to be visible without overexposing the lighter sections.
If you want to take really good pictures with your iPhone or iPad you need to enhance your devices, or perhaps just not use them at all. I'll come back to that last bit later.
