We headed out to Macworld earlier today to sit in on an interesting and informative tech talk that featured Stephanie Roberts, founder of Lens on Life Foundation and author of The Art of iPhoneography: A Guide to Mobile Creativity, who shared some helpful tips on mobile digital photography and some of her favorite apps for the craft.

The iPhone is now the most popular camera in the world, partly thanks to its small, portable, and discreet form. While you don't have much fine-tune control while you're shooting, you have lots of options when it comes to postprocessing apps to tweak and share your photos on the go. Below, a few ways you can use iPhoneography to your artful advantage, and some apps to download now.

Let your creative instincts guide you — Think of iPhoneography as a daily practice. Keep shooting and keep perfecting your craft. Since you'll want to be shooting throughout the day, collect moments that move you — whether it's colors, images, shapes, or scenes. Then, study your work over a period of time to find your true vision. It's also a great way to document your daily life and keep you connected to the practice of photography.

Craft your toolkit — Don't be shy about loading up your iPhone with photography apps. Learn about some of Stephanie's favorite apps after the break.

It's not unusual to see a designer smartphone with dumbed-down specs, but the latest entry to the designer gadget lineup seems to be packing both brains and looks. The Android-running Prada Phone by LG is a skinny one (naturally) at 8.5mm thick, and comes packed with a 4.3-inch touchscreen display, a 1.0Ghz dual-core processor for speed, 8GB of onboard storage, and an 8MP rear-facing camera so you can snap crystal clear photos of your daily outfits.

The signature Saffiano pattern on the backside adds a touch of class to the phone, while a whole range of Prada-branded extras, including a docking station, Bluetooth headset, and headphones, keep you accessorized. Unfortunately, for those of us stateside, the Prada phone will only be available in the UK for now (at a shockingly low price — free on a two-year contract), but you can fuel your dreams with a better look at the phone in the video after the break.
