There is a cool App available for iPhone and iPad call Arqball Spin. It creates those 360 degree rotating product shots.
Hack of course !
The trick to the whole "spin" is that the app records 20 seconds (20.02 seconds based on the company’s spokes person). The object needs to rotate smoothly one complete revolution in 20 seconds. For this, you need two things – a rotating surface and a motor .. a pretty slow motor. The rotating surface is easy. You may already have one in your kitchen. If not, they are under $10 – a Lazy Susan. The motor is equally easy, inexpensive, and you may have one as well – an electric screwdriver. I had a nice hand panted turntable on my dining room table and I had previously purchased the electric screwdrivers from a local big box store for $8.88 (the price should tell you the ‘falling prices’ store). For convenience, you will also want some way to have something to hold your iPhone (I grabbed a suction cup mount from my car).
Now for the only real trick – getting the turntable to rotate every 20 seconds.
Since the App uses an iPhone, just use the "clock: app which ahs a stopwatch. Place a small mark or something near the edge of the turntable (I used a kernel of popcorn). Gently press the electric screwdriver on the edge of the turntable and press the ‘on’ button. You may need to add something to the screwdriver shaft to add some friction (I used a little double stick tape). Now time how long it takes for the turntable to make one revolution. If it is slower than 20 seconds, you can wrap some tape around the screwdriver shaft. If it is faster than 20 seconds, you can use some tape of a bit of foam or something to make a tapered cone on the end of the shaft. The goal is to be as close to 20 seconds without going under. (If you are a little over 20 seconds, the final ‘spin’ will have a tiny jump at the end but if you are under, the recorded ‘spin’ will be a little over 360 degrees and it will look like it suddenly jumps backs at the end.)
With the timing corrected, place an object on the turntable, start the screwdriver and then start the app ‘record’ feature. The App will finish the recording automatically after 20 seconds and it will then render the final ‘spin’. If you like it, upload it to their website and share it !
