Love the different perspective this shooting angle gives

Bluetooth range is approx 10m, with a 15m mast the guy must be holding the Nokia over his head :)

I've tested and achieved much greater line of sight BT range than that - at least 30m, as from from the head that I could go and still visually detect movement.

Interesting to know mediavets, not that I'm likely to start using a mast anytime soon :)

Hello Kev,

Those photos have been taken by "valery44" (see our users database) with a Merlin on top of the 15 meters Mast.
The connection was made by a "PapyMerlin" BT module between a Nokia N810 and the Merlin...
This setting allow +/- 30 meters distance so this was not a problem (This "practical" distance has been measured by "mediavets" with a Tronisoft module, class1, and is confirmed by myselve for the "PapyMerlin")
The "PapyMerlin" BT module is a BT class 1 able to reach +/- 100 meters, but you should never forget that you have 2 partners in a BT connection ... and the Nokia has some limitations (Class 2)

Valery is only on his beginning for "Pôle panoramic photography" (semi-arial) and for a begin this is really a "master piece" !!!
I wish him more pics like this one ...

Cheers

Thank you Claude, trying to use such a mast in the UK is very likely to be frowned on. I've no doubt a license or authorisation would be required or it breaches some stupid law lol. Probably it would need 'planning' permission from the local council :rolleyes:

I don't believe that there is anything against using a mast, well there certainly wasn't here in East Sussex, as I used to own and run a pole photography company before selling it on and all that was required of ourselves was £3 million Public Liabiltiy insurance which we (proudly) never used. Always drew great interest when we were on site and had the masts raised. Even got a few commissions out of it from the general public just walking by and wanting then to have their house photgraphed from 18 meters aboe.

Regularly I was using an 18 meter mast and occassionally a 25 meter mast for the assignments, all vehicle mounted and used a tethered USB system to control a 360 horizonal/45 vertical head atop of our masts. New heads coming onto the market allow 360/360/360 movement and all three axis - really cool stuff using radio control.

Difficulty was having a "live" feed to see what you were shooting and being able to remotely control the camera. USB cable tethered using USB relays was the only way at the time using Breeze software for controlling Canon cameras. There was some use of using video transmitter/receivers that were plugged in to the camera and relayed to a base screen so that you had visual.

Interesting using a Merlin as it is quite a weight to lift 15 meters vertically, let alone safely operate at that height. The slightest breeze will cause the pole to sway. The head and P&S camera set up I was using weighed around 1kg > 1.3kg; the lighter the better with regards to being safe. The Merlin unit plus DSLR is going to be some weight to lift and hold aloft.

It seems you only need to have 2,600 Euros burning a hole in your pocket (for the mast) - and good insurance! - to be able to do the same.

Hello guys,

no problem of bluetooth connection with the mast 15 meters with merlin head ( controled from Nokia N810) this is more useful than a dangerous usb cable in the wind.. I have tested from 25 meters, it's work always well.

here is an ither exemple, taken at 10 meters hight, you can see the hole in the nadir with the merlin:

and ideally a van to mount it all in :) I carry about 70lbs of camera gear with me when I'm out photographing wildlife, not sure I could get much more on my back lol

jealous me? damn right I am lol

Yes, of course each need I have is not so much, separately, but each one at a time...
I have to learn before spending money. I have a question about these astonishing panos who seem to be in a state of levitation in the air: How is it possible to take the picture of the nadir from the top of the mast, without seeing it?

so, it seems you need more than "2,600 Euros burning a hole in your pocket (for the mast) - and good insurance! - to be able to do the same". it is always good to see knowledge appreciated over money, even if belatedly. ;)
cheers,
pns

The way that I used to do these was to take an upward facing shot from the base of the mast once it had been taken down. The upward nadir image was then patched within PhotoShop as you would normally do now.

Errr...isn't that a zenith image?

Hey Andrew!

That´s a great one . . . .

Some time ago i already thought about nagging away 1,5cm of the Merlin´s base on one side. The footprint would be much smaller then.
This mast reminds me of that idea . . .
The huge base is the Merlin´s only problem - cause the speed is remarkably faster using Josef´s controller.

I´m going to buy a Canon 5DMkII - so i also think about a fisheye for it. Maybe the 16mm Nikon FE - it covers a fullframe very well.
Gona try it at the weekend.

Thank you for the link!

best, Klaus

That suggests that Frederic might be able to make things go faster with Papywizard?

Why not the Canon 15mm fullframe FE? - that seems to be well thought of.

No, because it requires a real-time OS. I tried long time ago to do what Josef does with its controller, but it does not work (to be short, he first uses a manual move, check the position in real-time, and finally, make a goto move to be accurate. This is more or less what I do with the alternate drive, for moves <6°, but it does not work if I go faster - the alternate drive is faster than the short move, but still slower than a normal move).

Yep - Josef´s working hard on a new head. It´s gonna be faster, stronger and more precise - and more expensive than the Merlin (not a surprise, is it).
And of course it will be also controllable by the great Wizard of Papy :cool:
You made this a really great application, Frédéric!
So i think PapyWizard is a good compagnon for Josef´s controller which provides the basis features and this it does comfortably simple.
Adding special features needs the Wizard - that´s a good strategy!

As i read you´re working on an extended bracketing via N8xx/900 tethered? I didn´t read it closely yet - but that would be very fine of course!! :cool:

best to you, Klaus
