Home Made Panorama Bracket:
04/02/12This centre lens rotation is known as the 'Nodal Point' and if positioned correctly reduces Parallax Error which occurs when rotating across the sweep of a Panorama, this in turn allows for better stitching and less cropping of the final image.
Another reason for the special bracket is to allow the sections to be captured vertically rather than horizontally, the latter giving you long thin images.
These special Panoramic Tripod brackets range in price from £120 up to £600+ and whilst I would love to go out and purchase one of these precision machined brackets I simply don't have spare funds for this so not wanting that to stop me I have created my own bracket using:
1. An s/h 'Metz Flash Bracket' £10.
2. Some 'Video Lighting Brackets' from a skip - £0.
3. Some leftover Hammerite smooth Black spray paint
The Metz bracket needed a bit of sawing, drilling & filing, whilst the video light brackets just needed reconfiguring, drilling and new bolts adding etc, the end result can be seen above.
Having assembled the bracket and tested the camera to fit etc, the next job was to re-spray with hammerite and a blowtorch ... sounds insane but is perfectly safe practice if you’re careful.
The benefit of using a blowtorch is that it does give a great finish when using cans of spray-paint, just allow the vapours to go after spraying before hitting it with the blowtorch and sweep over the painted surface, don’t hold the flame on the painted area too long.
Still here and in one piece after my blowtorch hammerite spraying session last night and the bracket is looking good, cost so far £10.
The use of the blowtorch was essential working in the garage last night with no heating, I did consider putting the sprayed bracket in the oven on 100 deg but after careful consideration decided that the plastic parts might melt (unless I removed them) and the Missus would not be too happy either.
The next phase will be to test the bracket to check I have centred the lens correctly; there is a test on the web using two marker pens that appears to work.
I am also considering ways of adding sliders to the sides of the top section to ensure the crossover remains at 90 degrees.
Last phase will be to get outdoors with camera and test the bracket out properly.
