Seeing as I have a US iTunes account, which I dearly cherish, I got to download the Facebook Camera app, currently exclusive for iPhone, before its availability on other stores. So I tested it for a whole day on my iPhone 4S and these are my initial impressions.

It’s pretty fast. Once you launch the app, it takes you immediately to a news feed version for Facebook’s photos. You can see pictures that your friends uploaded and comment on them. This is where the pictures you take will go as well. You can swipe among the pictures your friends were tagged in. Loading the pictures is much faster than the regular Facebook app, which I think is horrible at handling pictures.

Facebook Camera is streamlined enough to post pictures on your Facebook timeline without much effort. Once you take the picture, you’ll get many filters to choose from before sharing your work. Those filters are a total of 14 (apart from normal). You access them by tapping on a brush button similar to that in Apple’s iPhoto app. They are similar to the filters you get in instagram but are named differently, obviously. You can upload pictures in batches, faster than with the regular Facebook app, and in higher resolution.

Once you’ve chosen the filter of choice, you click on the button to post. Now you’re back to familiar territory, similar to the Facebook app for iOS. However, you can actually save a post draft here in case you decided you wanted to save sharing the picture for later. That’s something I hope they add for the regular Facebook app.

Once you share the picture and it uploads, it’ll appear on your timeline as posted from “Facebook Camera.”

Overall, I think it’s an interesting app. I really like the icon, actually. But it’s not quite a home-run. Will it overtake instagram? I doubt that’s Facebook’s intention but they’re not betting right if they think it will. While it has its advantages, such as saving the original picture in your camera roll immediately after taking it, it has its drawbacks as well. For instance, it doesn’t save the modified picture in your camera roll, unlike Instagram.

Instagram has become so ingrained with users that uprooting it will take much more than an app which shares exclusively on Facebook and using it means flooding un-wanting users with pictures of things you find interesting but they have no interest in.

At the end of the day, where Facebook Camera falls short is in it not being a photo-exclusive platform. It comes with the baggage that is “Facebook.” Bonafide photography applications, such as Instagram and Camera+, cater to those who have a hobby for photography. They created an environment where those users can stretch their wings with exotic shots that they wouldn’t necessarily want to share with their Facebook friends.

Facebook Camera caters to the Facebook crowds whose pictures are less interesting than the Instagram crowd. But they are much, much more numerous. For once, however, Facebook has created a mobile app that is actually good. Hopefully that’s a sign of what’s to come for the regular Facebook app.

Brace yourselves, everyone, the Facebook Camera posters are coming.
