A full-frame sensor is better than APS-C or smaller to minimize the number of frames needed to cover the sky. Good noise performance at high ISO is important. ![]() It should be fairly obvious that the camera itself is an important part of an effective night 360 VR solution. Fortunately for us, the edge problems can be sidestepped by overlapping enough to use just the center portions of the frames. Using a fast ultra-wide or fisheye lens is better for reducing the time needed to take all of the panorama component shots, but these lenses typically have severe aberrations at the edges. Though you may see many online night sky scenes shot with medium to long focal lengths, aside from the sky-ground interface, they are not too difficult to stitch in many photo processing programs. Given the challenges mentioned above, the choice of lens (and camera) becomes critical. On individual frames, the exposures should be short enough to keep stars from trailing (shorter exposures for longer focal lengths), Between frames, there should be minimal delay to avoid star movement which will cause registration problems if the ground is also visible in the frame. This makes it necessary to take the shots forming the panorama in as short a time as possible. The second major problem to be dealt with is the movement of the sky. As with any 360 VR panorama, if foreground objects are part of the scene (certainly if the ground is included), then a special panoramic head is needed. While a daytime panorama can be done with care by hand, the long exposures needed for night sky panoramas make a tripod mandatory. Night Panorama ChallengesĮven for modern DSLR or mirrorless cameras, nighttime 360 VR panoramas are a challenge. 2014 - Click for interactive panorama viewing, then click on the circle/arrow at the top right of the viewer to start the interactive viewing session. While Google’s Pixel cameras include an impressively capable Astrophotography mode for single still images (at several minutes per shot), this isn’t applied to Photo Sphere panoramic shots.įrosty winter skies over Winter, Wisconsin - 14 Nov. The second problem is that at night, the exposures need to be many seconds long (at least), during which time the earth’s rotation is causing the stars to appear to move relative to the horizon. ![]() ![]() This is particularly hard to do with cell phones, especially if you have to be watching and poking at the screen behind the lens. If you’ve taken panoramic shots before (not necessarily a full 360 degrees), you will know that parallax errors occur if the panoramic photos are not taken with the camera rotating around the lens nodal point. First, stitching may not be accurate if objects are close to the camera. While these quick Photo Sphere panoramas are surprisingly good, there are a few limitations. Click for interactive panorama, then click on the circle/arrow at the top right of the viewer to start the interactive viewing session. 2017 - Photo shot with a Google Pixel 3A XL phone.
