As for the new update, its adds remote shutter control which basically allows you to click a picture from your Moto X, G or E’s smartphone camera via your smartwatch. Yes, the app runs on any Android Wear smartwatch, but you will need to have a Motorola smartphone to do the same.
The update makes taking photographs remotely a breeze. You simply turn on the camera app on your smartphone and your smartwatch will immediately prompt you with a notification, which then opens an app with a shutter button. No, there is no live view feed (similar to Wear Camera) getting streamed on to your smartwatch, but it simply allows you to preview the clicked image on your smartwatch before dismissing it.
The update as you may have noticed is pretty similar to Google’s Camera app that offers a similar level of functionality. Other updates to the Camera app include compatibility with Android KitKat and performance and bug fixes for the same.
