You could also try a smaller/taller bottle cap, but my strategy so far has been to: Sadly, the down-most shots may capture your bottle cap and/or top-of-the-tripod-platform, so to help reduce that I cut a little slit in one side of the bottle cap.
You can then sit the tennis ball inside the (upside-down) bottle cap and can rotate left/right and up/down without the lens in an (almost) perfectly fixed spot.
All tripods have a small 1/4 inch screw which pokes a small way out the top and if you drill a hole (using the nail scissors) into the bottle cap the right size, the bottle cap will screw right on it. One neat feature of this tennis ball is that I also had tripods in mind. The capturing should take about 90 seconds, and hopefully the processing will be *relatively* fast because the stitching won't have much trouble. The video shows what this looks like nicely.Ĭlick the "stop" button and wait for your photosphere to process. For the very last shot, directly down, you should get your camera approximately in place, but will probably want your feet out of the shot, and the string out of the way too. Tilt up and take the top rows (you may have to squat and look awkward for the directly up shot (or if it's sky don't really bother). The string is essentially keeping your camera at a fixed point. Make sure the end piece is always dangling perfectly over the bottle cap when you take a shot. Take your first picture, and then rotate around to the left or right to get the first row. Turn your phone upside-down and insert into the tennis ball with the camera centered and looking out the hole. Start the photosphere application (on your Galaxy Nexus, select the camera, then hold down the camera icon and chose the photosphere icon). Adjust the height of the end piece so it hovers about 2 inches above the bottle cap when you stand. To use the device by itself, hold the tennis ball at chin height, and let the cap fall to the floor. The "poor man's tennis ball photo-sphere helper", laid out on the table. Tie a knock in either side so the three pieces stay connected. Take an 8 foot length of string (should be taller than you are), thread it twice through the end piece (the end piece will be in the middle), then thread one end into the little hole in the tennis ball and the other end into your bottle cap.Use some nail scissors to drill a tiny hole into the bottom of the tennis ball, another though the end piece, and one in the side of the bottle cap.Check that your phone can take picture out the front - you may need to trim the hole wider.

(the video shows how to mark accurate cutting lines) Cut a slit so that your smartphone can sit upside-down with it's lens resting in the dead center of the tennis ball.Cut a out a small circle at the front for the camera to look out of and keep the circular "end piece" that you cut off.The video explains better, but basically you want: 8 mins (about the same time as it takes to make) How to build your own "poor mans tennis ball photosphere helper" And sure it looks a little dorky, but it gets the job done, and you can make your own very quickly! It's a fun little project I call it the " tennis ball photosphere helper". On this page I have a cheap way you can reduce parallax using a tennis ball and a string. This introduced " parallax error" which can ruin the stitching and affect the quality of your final photosphere.īecause of how parallax works, the effect is worst with close objects - so if you're taking a photosphere of far away scenery it might be fine, but if there is any tree branch, or chair, or even the ground, which comes too close - you will probably get a funky photosphere.Ī tripod can help, but it's not very portable, and unless you pay top dollar for one that can rotate around an arbitrary axis, your lens will not stay centered when you tilt, and the tripod is a pain to carry around. Unfortunately, as you're spinning in a circle, and pointing your camera up or down, it gets very difficult to keep your camera lens at a fixed point. Using Android's "photosphere" (part of the new Google Camera) you turn your smartphone to take a photos in every direction, and then it stitches them together into a 360 degree panorama or " photosphere" which you can then interact with and/or upload to Google maps.
