I'm shooting with a 12' time lapse slider - it's the Dynamic Perception rig, but with two 6' sections fastened together.

Here's what a 6 foot setup looks like: http://3.bp.blogspot...ynamicdolly.jpg

I want to rig the camera/head UNDER the track, and be able to "look down/ahead" the length of the track, be it a push-in or a pull-out. It IS possible to undersling the carriage/head setup.

The issue is, the camera will SEE the tripod, or whatever is holding up that end of the track. When it's not underslung, you just have to tilt the camera up a bit (like any dolly shot/push in). But for underslung, how could I rig the far end of the track UP in the air without seeing what is holding it? I've imagined C-stands with super long arms reaching in from outside the frame, or speedrail, or menace arms, I just don't know. Steadiness is a huge factor. As far as mounting points, I can easily get a baby pin to stick off of the track at multiple points via 1/4-20 to baby adapter, or cardellini. So there's that to grab on to.

Preferably, the setup would be afforable to buy, and small enough to breakdown into a large sedan. I also plan to shoot with it in the wilderness. I do realize sandbags may be a part of the equation.

Thanks!

Wilderness sounds like some sketchy terrain to stabilize your rig. First of all, you'd need to level out your supports. A combo of c-stands with rocky mt. legs, apple boxes and shot bags should do it, but that's not compact or resourceful.

I was in Maine for a while shooting on an igus based slider. NOT STABLE AT ALL. What we discovered to work very well was a popup crafty table (crafty wasn't too thrilled to have a table hijacked). Maybe try something along those lines of supporting it with a continuous platform as opposed to single points which will cause bowing from variable tension in the track. Plywood and saw horses maybe?

Also, something like the emotimo pt could help you add another dynamic to your shots and frame out the rig throughout.

What have you got in the area in terms of things to tie onto ?

with adequate trees and rock faces that rope or tie downs or whatever could attach to you could create a sort of 3d truss out of tension members (i.e. rope and other things that flop about) - lock it down in 3 dimensions at leach end.

Tricky, without all those things to tie off to.

You could make your own towers out of shot and suspend down from them - a heaaaap of gear and considerations though...

Basically, you want to build a bridge with support at only one end. You need a tower (rocky-mountain combi-stand), some cable (either wire rope with turn-buckles and shackles or ratchet straps), and some counter weight (sand bags or shot bags). You want it portable and stable. It gets tricky if you want to do a push/pull rather than a track across. Maybe a pick and shovel will work better to get those low pushes.
