In addition to a computer, QuickTime VR authoring
software, and a camera with an appropriate lens for the look
you want (wide or flat), what else do you need to produce
QTVR content? There are several levels of need which blur
together to form a continuum. The following examples attempt
to show both extremes and the middle of the road equipment
used to create panoramas.

The lowest range of
hardware acquisition
Nothing. Yes, that is correct, you need nothing more than
a camera to take QTVR panoramas. You hold the camera (in
portrait mode) up to eye level with your arms tucked in
against your body. The idea is to snap pictures which
overlap by about 50% (easy to guess at while looking through
the view finder) all the way around for 360 degrees of
images. By holding the camera steady, and arms tucked
against your body, the images will be fairly consistent. You
may want to lean back a little bit while in this position to
help put the camera lens above your body rotation. Once you
take your pictures, get them into the computer in some
fashion (PhotoCD, scan the images or negatives, or use a
digital camera). You will need to do an interactive stitch,
but the results are not bad. You will probably need to crop
the top and bottom of the resulting stitched image to
account for inaccuracies while shooting the panorama. This
technique is a good way to get a partial panorama or just a
super wide photograph, and is good for those cases when you
do not have all of your QTVR geek gear. An example of shooting by hand can be found on
the Tips and Techniques page.
The middle range of
hardware acquisition
A decent tripod should be on your list. The weight of the
camera to be used and type of use in the field should help
you determine the best tripod for your needs. In our case,
we found a used Bogen (Manfrotto) #3001 medium duty tripod
with a Bogen #3047 pan/tilt/swivel head (panhead). The cost
was around $80 USD for the tripod and head. We then attached
a new Bogen #3115 (Manfrotto #138) 3-inch ball camera
leveler ($60 USD) under the panhead. The ball leveler is
used to level the rig and the panhead is used to pan the
camera to get a 360 degree panorama. You could forgo the
ball leveler and level the panhead by adjusting the tripod
legs - you will only do this once, maybe. The other solution
for leveling is to add a second panhead in place of the ball
leveler. We like the ball camera leveler solution as there
is only one adjustment and it does not add significantly to
the height of the rig. We chose this route for our basic
tripod set-up as it is solid, simple, and would work well
for our underwater needs. Be sure the tripod, leveling head,
and panhead are sturdy enough to handle the torque created
by the weight of the camera rotating off center of the
panhead rotation axis. Remember, the lens nodal point sits
at the center of panhead rotation, not the camera. As you
rotate around to capture your panorama, be sure the camera
stays square and level with the rotation axis of the
panhead. The bottom line is to get a good, solid tripod to
support the camera rig you place on top of it. A poor
quality tripod setup will most likely result in poor quality
panoramas.
Note that we do not use a fancy click-stop panhead. We
found we could get consistently excellent results with the
standard panhead of the tripod with a ball leveler head
sitting below to level the entire rig. We use the standard
compass marker on the panhead for panning demarcations when
we shoot our panoramas. The Bogen #3047 panhead has 24
demarcations for panning which works out great for 35mm
lenses on land and 20mm lenses underwater when you use a
strobe. We have created additional demarcation plates which
sit on top of the default marker with 24 (12 if you use
every other mark) and 16 demarcaions for the different
lenses we use. From our experience, it is not too much
trouble to accurately line up the camera with the panning
demarcations as any error is fixed up in the stitcher with
its "range" parameter to help find the correct image
overlap. Other folks have also found that the click-stop
mechanisms are not needed by everybody. Kaidan
(http://www.kaidan.com) has a product
called the KiWi
(http://www.kaidan.com/kiwi.html) which
is simply a pan only head with a built-in L-bracket that
works for most camera/lens configurations. The Kaidan
KiWi is avaialble for around $100 USD.
Once you get your tripod and panhead story figured out,
you need some way to mount the camera in a vertical fashion
to the pan head. You can mount your camera horizontally and
create excellent panoramas, but mounting it vertically will
get you a greater vertical field of view. To mount your
camera vertically, we recommend building a custon L-bracket
as the cost and labor is minimal. When making the L-bracket
you need to be sure the nodal point of your camera lens sits
over the rotation point of your panhead. Here are some
simplified instructions: cut the bar stock into a 4" length,
mount the quick release plate to it, cut another piece and
put a 90 degree bend in it, bolt this one to the first.
Mount the camera to the vertical side of the bent piece and
you are done. All said and done, We spent about $200 USD for
the entire setup. It is simple, works well under water, and
is indestructible. A
step-by-step example of building your own L-bracket and
pan-markers can be found on the Photographic Accessories
creation page. If building your own is too much trouble,
you can buy adjustable L-brackets (with left-right and
front-back adjustments) from your local pro-camera shop. Be
sure there is enough play to adjust the lens over the
panhead rotaion.
Putting it together:
- We found a Bogen tripod (#3001) w/head (#3047) for
$80 USD (used)
- A Bogen ball camera leveler (#3115) which sits under
the panhead for $60 USD (new)
- A home made L-bracket made from 1/4" x 1" x 5'
aluminum bar stock purchased at your nearest hardware
store at $5 USD for a length much longer than you need
- A Bogen hex plate quick release mount for the
L-bracket $7 USD (new)
You have now become a semi pro QTVR equipment owner. You
have your basic tripod, leveling panhead, and camera
mounting L-bracket. You are now ready to join the world of
QTVR photographers. The hard part now is learning to make
good use of your equipment. Simply owning the equipment does
not make you an expert, so now you practice, practice,
practice. Have fun, go create kool panoramas!
After hauling a heavy tripod rig around for a while you
may consider graduating to a monopod. These are extremely
lightweight, set up extremely fast, and do not draw much
attention.
Monopod first pass: A step
backward
Since we are not using a panhead, you need to rotate the
pod itself and use the viewfinder to guess at 50% overlap.
This is pretty easy since 50% is a simple overlap to be
consistent with as long as you pay attention to the images
you are taking photos of. Herein lies the next problem.
While you are busy looking through the viewfinder to compose
the next image, it is very hard to look at a bubble level to
help prevent wobble between shots, hence the guess work.
This technique is possible, however, and you end up with a
slightly better version of the technique of holding the
camera to your eye with your arms tucked in against your
body. We clearly would like a panhead of some kind to help
with leveling and image demarcation for consistent image
overlap. With the amount of guess work involved in
overlapping the images, you will probably need to do an
interactive stitch to help the stitcher do its job.
An example of shooting a
panorama with a monopod can be found on the Tips and
Techniques page.
Monopod second pass: Two
steps forward
What of the panhead you ask? There is a simple solution
to this: Make use of the Earthly environment we live in -
use a combination of a compass and a bubble level. Rather
than the degree markers on a standard compass, place image
demarcations around the edge for the number of images you
need. Place a bubble level below (or on top of - whatever
works best) the compass and attach this unit to the side of
the monopod. For each image, make sure the bubble is
centered and the compass needle points to a demarcation line
on the edge and snap an image. You then rotate the pod so
that the compass needle points to the next mark, level the
bubble and snap the next image. This gets you in and out
quickly without hauling around a bunch of equipment.
A step-by-step example
of building your own monopod pan head can be found on the
Photographic Accessories creation page.

The highest range of
hardware acquisition
You have now decided that QTVR content creation is your
calling and you intend to make a career of it. You are
probably already a professional photographer and would like
to augment your business with QTVR and want the highest
quality and most versatile QTVR creation equipment you can
find. You are probably interested in doing both outside and
inside panoramas, and will probably create panoramas in a
studio atmosphere. For this work you will probably be using
only the highest quality cameras and lenses, using both
digital and traditional imaging and you want a set up that
can handle this versatility. You will probably demand the
highest exactness of camera, panning, level, and nodal point
settings. For this type of situation we recommend using a
heavy duty Kaidan click-stop pan head and camera L-bracket.
You will want a quality, heavy duty, tripod that will not
bow or rock as you image your panorama. A tripod dolly may
also be required to enable ease in location changes. In
addition to the camera tripod environment, you will need the
traditional support equipment used in professional
photography such as lights, reflectors, gels, backdrops,
cables, sandbags, support crew, etc.
