In its Blog Spot Instagram revealed the new features for iOS. Instagram would now have a themed shutter and shutter release button and you would be able to preview most recent photos on the camera roll. Another improved feature, tilt-shift, allows for more precise blurring and a “vastly more realistic rendering of depth of field,” boasts Instagram. To its array of filters Instagram has added another filter called Willow, it is a black and white filter which lends purple haze to the photos. “This filter works well on portraits, still life, and architecture photographs with contrast,” according to the post.
