Facebook has released a new update for Instagram for iOS that bring with it new features for users to enjoy. Along with the new features, the update also brings forth performance tweaks and a few fixes for tiny bugs that plagued the app.  

The most important feature that experienced improvements via this update is the Lux feature. Finally, Facebook has brought some needed control to Lux, and Instagram users should feel quite happy about it.  

What is Lux?  

It's that little icon that resembles a sun, and its purpose is to make your pictures look better. It was added to improve images that are underexposed, and having an anemic look. However, there was a problem with Lux before this update, one that didn't give users greater control over the feature.  

Previously, Lux was basically an all or nothing feature, as there was no way to manually adjust the image to the user's liking. If a user wanted to find the middle ground between the original image and the version after it went through Lux, they would be out of luck. Now, Facebook has added a custom slider that allows users to manually choose what they want the image to look like, instead of delivering the standard Luxified look and feel.  

At the moment, there's no word as to when the new improvement to Lux will find its way to Android and Windows Phone, but we're guessing it might not be too long from now.  

Speaking of Android, Facebook updated that version of the Instagram app, as well. The changes are nothing to get excited about, just a lot of performance improvements here and there.  

"These changes mean a faster, more responsive app. Your profile screen now loads twice as fast, and we've cut the overall app size in half to increase speed throughout Instagram.  

By making our design cleaner, we've also made Instagram for Android easier to use. We've simplified our visuals throughout our app, making use of valuable screen space for small devices and feature phones and rearranging our design to keep buttons within easy reach as you navigate the app on a larger device," says Instagram on its blog.
