Facebook Camera is 4.9MB and will work on the Apple iPhone 3GS, Apple iPhone 4, Apple iPhone 4S, Apple iPad 2 and the third-generation of the Apple iPad. It requires users to be running iOS 4 or higher.Instead of posting one photo at a time, the new app allows you to share multiple pictures at one time; simply check a box next to the pictures you want to share and hit post. Additionally, Facebook Camera has a built-in Photo Editor that gives you options for your photographs that are similar to those on Instagram. For example, with the pictures from your iOS camera roll, you can crop, rotate and add filters to change the look and feel of a photo.
The Facebook Camera app does leave out some of Instagram's social functions such as using a hashtag to file a picture under a specific topic like #LeBronJames or #DwayneWade for example. While it would seem odd for Facebook to offer this app after purchasing Instagram, according to The Verge, the team that was working on the app had been working on the project for months and probably was not given the information that Facebook was going to be making the acquisition. Project Manager Dirk Stoop told the site that sharing photos quickly and in higher resolution are the main goals of the app. In other words, Facebook Camera tries to knock out a niche for itself against Instagram which is somewhat ironic considering that Facebook now owns will own the competition once the regulators sign off on the deal. In its IPO filing, Facebook said it had hoped to close the deal during this quarter.
