Big Helium Balloons & Aerial Photography?

[MiniMan64]

Bit random this one so bear with me...

At work I have come into possession of a large latex balloon (a 1600g?) and a Go Pro camera which I believe, given there was a parachute in the box as well, was intended to be the basis of a project to take pictures in space. It's being living under a colleagues desk for 2 years and while I'm not sure I'm confident enough to attempt the original mission, someone has suggested we could have a go at some aerial photography of our building and local area?

My question I guess is does anyone have any experience in this area? I believe the balloon is about 2m across so some rouhg fag packet calculations say I need about 3-4 litres of helium, how much will that cost?

Is the rest just inflate balloon, tie camera to it, tie string to it and away you go?

The balloon will pop when it reaches a certain height, you then have to track the camera and collect it providing it hasn't been broken in its fall. There's a PHer that does this kind of thing, have a look in the photography section.

I believe the original intent was to send the camera into space as part of small payload that included a GPS tracker but given we're in Devon there is a large possibility of a sea landing. That along with other reasons means this time we may go for a tethered balloon so we can easily retrieve it.
