Instagram just received a very big update, and this update isn’t just bug fixes or new filters. This new update will make your photos look much more beautiful than they are.
Along with a new brushed UI, Instagram has added a new feature called Lux. What Lux does is, it enhances your dark part of the images. This way the ares of your photo which aren’t visible in because of low exposure, are made vibrant. This can be used with the filters or without the filters. Lux is just like HDR feature on iPhone but this can be done even after taking the photo just incase if you need it.
Here are some images which would help you understand what exactly happens when you tap the Lux button.
