In addition to the Google Camera update that rolled out earlier this week that brought Android Wear remote triggers for cameras, Google also found some time to show some love to the Photo Sphere portion of the app. While it was noted in the list of changes, it never really highlighted what exactly had changed but thanks to a post from Evan Rapoport on Google Plus, we now know.
Much bigger targets - The most noticeable change is that the targets are far bigger, making it easy to see them even in bright sunlight (like this beach scene in my image here). I've really loved using this and it makes the capture process faster and more fun. Please try it this weekend, share your photo spheres on Google+ and Views (g.co/views), and let me know what you think!
Performance improvements - We also significantly reduced the memory consumption used during stitching. This, combined with some other fixes, will prevent some of the crash reports you've told us about. Note that all these changes also apply to the Pano, Wide Angle, and Fisheye modes, which are based on the Photo Sphere codebase.
The update has slowly trickled out, so most folks should have it downloaded by nor at at the very least having it showing as available for download. Have you grabbed it? If so, have you checked out the Photo Sphere updates? Let us know how they're working out for you in the comments if you have.
