En route to Dallas. Clouds never get old. Agreed ? Hyperstereo - probably my ten thousandth - of ice-cream castles in the air viewed from the plane at about 30 thousand feet. The left and right shots were taken probably 3 seconds apart. If the plane was moving at 300 miles an hour, that's a baseline of about ... a quarter of a mile - right ? Bri
@rocketmoon_az --- You want to make stereos ? Good !! Well it's easy in principle - you just need to take two pictures from two viewpoints horizontally separated by - in normal circumstances - about 3 inches. But you can take them one after the other (sequentially) with just one camera by moving the camera sideways between shots - and any normal camera will do - I used a normal iPhone for this stereo and I let the plane move me between shots. In this case a long way - because the clouds are a long way away. But this technique only works if the subject matter stays still! If it's a moving subject, you will need a stereo camera. That might seem an easy thing to make, but it's really not. You have to fully synchronise the shutters and the apertures and the focus. Any ideas? Bri
