This morning Yahoo rolled out an update to its Flickr for iOS app that ushers in several new photo filters as well as the ability to customize filters and tailor them to suit your taste. Additionally the application has a new feature which the Flickr team is calling "Live Preview"
Live Preview is a new concept that we have not seen on many apps in the past. This feature allows you to preview the selected filter in real-time before taking the photo. This allows you to see which filter looks best for the scene you are composing before you press the shutter button. Rounding things out, the app now includes a few handy features such as a grid, focus and exposure locks, pinch-to-zoom, and even includes new tools like sharpening, color balancing, and levels adjustments.
