In Perspective, Fun: Shooting without a Pentax 645D from an helicopter

And no, the camera is not a Pentax 645D, but a NEX 5. The helicopter would not lift the 645D.

Jerome,

Hmm! What else can the 'copter carry?

I have always thought that aerial pictures can make interesting art! So where's the helicopter? Can we have a picture of the setup? :)

Aerial views reveal patterns otherwise not noticed.
Yann Arthus-Bertrand's work has shown this in an impressive way.
New Project?

Best regards,
Michael

So Michael,

Do you have one such helicopter or you borrowed it? I'd like to see how it's setup! Thanks for the reference to Yann Arthus-Bertrand. I'll look it up.

I'll try to take a picture of the setup, but it will take a few days.. It is a small quadrocopter onto which I attached a NEX-5 camera taking video (this is just a frame extracted from the video, photographs would be much better). It can lift about a kilogram and the NEX is a third of that.

Beyond the humorous reference to Nicolas post, I wanted to remind that remote controlled platforms of this kind are becoming increasingly popular for filmmaking, because of the obvious savings compared to a real helicopter. More professional platforms in the 3-5 K€ range would have no problem lifting a 645D and the equipment for a video downlink allowing precise framing from the ground.

The basic structure is a kit (DJI F450), the landing gear and the corks is my design. The corks protect the propellers. Flight time a bit less than 15 minutes with the camera. The camera is simply used as a camcorder, the original idea was to film the ground vertically from above. Most people use a gopro camera, which are much smaller and lighter.

The main limitation is the wind, because the whole machine tilts when it needs to accelerate and the fixed camera tilts with it. I am building another one where the camera would be stabilized and the platform controlled by GPS.

The magic allowing these machines to fly is done in the electronic controller. There is a controller named ardupilot using free software and I'll use that controller for the next kit. It can also be used with fixed wings airplanes, which can fly much longer with bigger loads.
