If you love taking pictures with your iPhone, you have probably already realized the limitations of the built-in Camera app. One of the best alternatives in the App Store has just gotten better with a fresh new 2.0 update.

Snapture 2.0 just hit the App Store with a host of new features, including tap-to-focus on the iPhone 3GS, instant photo sharing to Facebook and Twitter and three color filters that allow you to take photos in black & white, sepia or negative (inverted) in addition to full color.

Boasting over a half million satisfied customers, Snapture’s previous version already held an impressive lead over the Camera app with high-speed multishot, the ability to tap anywhere on the screen to take a picture, TouchZone stabilization and much more.

Snapture’s patent-pending Quickview technology lets you snap a picture and instantly see the result in the corner of your screen. Press and hold the picture and you’ll get a closer look. You can easily e-mail a good photo or delete a bad one by sliding the thumbnail across the screen, avoiding a trip to the Camera Roll.

Best of all, Snapture 2.0 is now only $1.99 — that’s 75% off for Thanksgiving (and as always, a free update for existing customers). It’s a great addition to your holiday photo arsenal!
