Given the stiff competition from other photo editing apps, Yahoo is approaching its Flickr renaissance with steely determination. Today's update to the iOS app introduces a slew of new features designed to give it a fighting chance in a crowded market. Love 'em or hate 'em, filters remain all the rage, and Flickr is rolling out a handful of new ones with suitably hip names to please the masses. Now, users will also have the ability to see a live preview of the filter before they apply it to their photo. Also included in the update are several beefed up -- and free -- editing features, like color balance settings, level adjustments and a sharpening tool. Lastly, the camera function is getting a minor overhaul as well. You can now pinch to zoom, compose a shot with the handy dandy grid and lock your exposure and focus points.
