Yesterday, Google finally announced Android 4.3, a minor update to 4.2 that included a handful of neat features, including the ability to have more than one user profile. As time has progressed, however, a few other unannounced features have been discovered.
First, Googler Evan Rapoport posted a detailed description on Google+ about the serious enhancements the Photo Sphere team made to the functionality in Android 4.3. Rapoport says that nearly all of stitching and exposure bugs and annoyances present in Android 4.2 have been fixed in the latest update.
First, alignment and stitching are much better, giving you more level horizons and fewer errors throughout the image. While environments with lots of moving things are always challenging, scenes like the one attached here with a long flat horizon are now much better.
Second, we’ve improved exposure compensation for each individual frame, producing a beautifully exposed photo sphere. You can compare this to the previous versions that produced gray areas and inconsistent coloring in areas of high contrast (near the sun, horizons, buildings against blue sky, etc.).
