| Video : create a complete Quicktime VR 360-180° in 10 minutes [not a basic tutorial :-] |
| This vidéo explains how to create a complete spherical Quicktime VR (360°-180°) in 10 minutes, step by step, from the shots to the stitching part. (video format: H264 - mini. Quicktime 7.01> apple.com/quicktime/ - soundtrack: English) Thanks to Robert Haddock and Christine Collier-Roberts for their help. (voiceover and translation) |

| A smaller hole on the nadir = less work in Photoshop |
| With a 10.5mm Nikon lens, the size of the "hole" on the nadir, when creating a Quicktime VR, can be significantly reduce, and then reducing the amount of work in Photoshop. To do this, you simply need to tilt your camera when shooting the last 6 shots row until you can see the panoramic head in the lower part of the photo (-10°, -15°...). The size of the circle to edit will then depend on the size of the panoramic head used. |

| Quality There is almost no quality difference in the overlapping area with the zenith if you shot your pictures with a closed enough aperture, choose FINE or RAW as your saving parameters and with an angle allowing a good overlap.The following details are from a 'normal' render (0°) and a render with tilted images (-15°) of 10.000x5.000 pixels/Smartblend. |

| Nadir patching The correction of the nadir can be done easier and quicker now. It's possible, if it doesn't have a lot of details, to use only the "patch" tool without using the 8th photo (often taken handheld). For more information, watch the video about the realisation of a Quicktime VR : |
| Hardware For all these tests, I used a Nodal Ninja 3 (http://nodalninja.com) panoramic head because it has a very small base. (Thanks to Bill Bailey for his help) |

| Ce montage permet de réaliser une vue sphérique en trois photos sans avoir à photographier le zénith et le nadir. Après avoir enlevé le pare-soleil du Nikon, l'angle couvert est de 200° (!) sur le capteur "fullframe" du Canon EOS 5D. Les avantages sont nombreux et simplifient la vie, de la prise de vue rapides de scènes d'action, à celles dans un espace réduit ou dans des conditions difficiles. Plus qu'un fisheye 8mm, Sigma ou Nikon, cette optique couplée à cet appareil photo permet des panoramas originaux et de bonne qualité tout en diminuant le niveau des contraintes. Les Quicktimes ci-dessous sont assemblés avec PTMac (Mac OS X) ou PTGUI (PC / Windows). Note : Tenter de retirer une partie du pare-soleil peut facilement entrainer des rayures sur la lentille frontale (ou pire). |

For most spherical heads on the market, setting the "nodal point" requires patience and a minimum knowledge. Even when it is set, vibrations, transportation, shocks... will make you the operation regularly (most of the time, when you do not have time to do so). 360Precision works on the opposite principle: it has been designed for a couple "camera body + lens". It has no customizable setting, apart from the spirit level. > see the video |

| Basic
informations to create a clean Quicktime VR 360°-180° |
|
|
There are as many techniques as different ways to build a panoramic image or a spherical Quicktime VR through stitching. The one described below is one amongst others. It probably is the easiest one to reproduce. It's up to you to adjust it according to your needs. (as the above article) |
|
|
For greater ease, this example's shooting is based upon an horizontal row of 6 pictures, a top view (zenith) and a bottom view (nadir) using a VR head mounted on a tripod. (see graphics below) |
|
|
|
- Photo: The camera must be set to manual mode for focus, exposure and white balance to avoid any offset of the point, light and color setting between images. - Photo + head: Beyond the correct mounting of the head and camera on the tripod, you have to define the nodal point to get pictures that are easy-to-assemble. Alain Hamblenne wrote an interesting Web documentation and PDF on an adjustment method called "the grid": http://www.outline.be/quicktime/tuto/ (available in english and french) Arnaud Frich is giving large details on the topic and on the ways to operate these different settings (french only): http://www.arnaudfrichphoto.com/gp_point_nodal.htm Manfrotto also has a page dedicated to the subject: http://www.manfrotto.com/303SPH/main.php?cnt=howto#sph |
