![]() When viewing a sphere in the Android gallery app you’ve also got the option to convert it into a ‘Tiny Planet’ image. If you open a sphere in the gallery app you have to tap on the sphere symbol at the bottom …Īnd then you can view it in ‘sphere mode’ to get the full effect of your Photo Sphere. If you open a Photo Sphere in the Android 4.2 standard gallery app it is first displayed like any other image, but you can open the Photo Sphere viewer by tapping on the icon and then zoom in and out and ‘move’ through the scene using the familiar pinch and swipe gestures. The easiest way to do that is on your phone. Viewed in a dedicated sphere viewer you get the impression of being immersed into the scene and even moving within it. Of course looking at a Photo Sphere with a standard image viewer is only half the fun. With most image elements at a distance from the lens and no moving subjects, this sample shows fewer stitching errors than the sample above. As you can see in the full-size version there are much fewer stitching errors in this sphere than in the one above. Like many panorama apps, Photo Sphere struggles with moving subjects in the frame.īelow you can see another sample sphere that was captured in a park, with most objects in the image further away from the phone’s lens and no moving subjects. Stichting errors occur most frequently on objects that are close to the camera. Few photographers would think about using one of those with a smartphone, but you can definitely improve stitching quality with the right capturing technique. The rendition of the latter can be improved by rotating the device as much around its center point as possible when capturing the sphere images, without changing its position in space - this is exactly what a panorama tripod head would do. However, like many panorama apps, Photo Sphere struggles most with moving subjects and image elements that are placed close to the camera. In the standard view the final sphere pretty much like any other panorama, you’ll need to view it in the gallery app’s Photo Sphere mode or on Google Plus to appreciate the ‘immersive’ experience. This is visible just below the bright reflection on the front of the left building. Exposure differences between two frames can cause some trouble, too. As you can see in the sample below, the stitching is far from perfect with a number of stitching errors and ‘vanishing’ moving subjects. On the 5MP Galaxy Nexus, you’ll capture a 360° panoramic image using Photo Sphere with an approximate size of 4600 x 1600 pixels. You can already move through the sphere by moving your phone around, but only in the final version will the app make an attempt to even out exposure differences between the inividual frames and correct for perspective errors. This takes approximately 40 seconds on the Samsung Galaxy Nexus.Īs you go along the individual images are stitched together in a rudimentary way. Once all blue dots have been aligned, you have to hit the shutter button to start the rendering process. They’ll appear as black circles in the sphere. When you’re finished capturing the invidual frames and no more blue dots appear, only two small areas at the ‘poles’ of your sphere remain uncovered. However, you’ll have to keep going until no more blue dots emerge on your screen in order to render a complete sphere. ![]() You can terminate early by tapping the shutter button and the app will start rendering the final image using the frames you have captured up to this point. This process continues until the entire sphere around you has been covered. Again, an image is taken as soon as the blue dot and the circle align, there is no need to press the shutter button. ![]() ![]() Once the first image has been taken, more blue dots appear above, below, left and right to indicate where you should to point your device to continue capturing the individual frames to create your sphere. ![]()
