When
you think of panoramic photos I would bet that super-wide
photos of rolling hills, or weirdly distorted building
interiors, are the first things that spring to mind.
Well, as they say in the classics, “It ain’t
necessarily so”, the modern digital panorama
can have just about anything as a subject.
Traditionally
panoramic photos have been taken with cameras specifically
designed for the job, either a fixed lens type like
the Linhof Technorama, or cameras with rotating lenses
like the Noblex. Fixed-lens cameras, despite producing
a wide-looking photo, typically sport a 90mm lens,
which on the 6x17cm format, is just a mild wide angle.
The photos are not as wide as they look, but at least
there is no discernable distortion.
The rotating-lens cameras do produce very wide images,
up to 360° in some cases, but unless used carefully
they can produce some very weird distortion.
That’s
all very interesting but, as the owner of a digital
camera, what do you care? You have the ability to
produce stunning panoramic photos similar to those
made by special panoramic cameras, with little or
no investment over and above the camera you already
own. Yes I know you can spend a fortune on a specialised
panoramic tripod head, but it’s not strictly
necessary, all the photos accompanying this article
were taken hand-held.
If
you define a “panorama” as I do, which
is to say any collection of contiguous images that
have been stitched together to form a single photo,
then your world opens to vast array of possibilities.
Using digital stitching techniques we can have the
best of both worlds, straight-looking photos, or extreme
wide-angle shots.
I
often shoot panoramas of wildlife, flowers, and insects.
Of course there is a caveat, the subject must be stationary
for at least a few seconds, but apart from that there’s
no reason a grasshopper is not just as valid a subject
as the field in which it lives.
Now
many of these photos have quite narrow fields of view
(FoV) and could have been made with a lot less work
by simply cropping a single exposure, so why bother
with the extra hassle? As a working photographer I
am naturally trying to sell my photos in one form
or another, and generally, the larger the image the
larger the cheque. Even if this doesn’t apply
to you, just imagine how big a print you can make
from an image 7,000 pixels in length, I even have
one that’s 20,000 pixels wide that would make
a very nice 100-inch mural. That’s 2.5 metres
wide, and without any up-resing; try that with a single
exposure, even with the latest 16mpx cameras.
With
the examples in this article I hope to convince you
to think outside the square a little, and start seeing
all kinds of things as possible subjects for the panorama
treatment.

Freshwater
crocodiles are not particularly aggressive, and those
at Windjana are more passive than most. Still, I don’t
fancy the idea of sticking a $10,000 Linhof Technorama
and wide-angle lens in its face, not with those teeth.
In
the digital world however it’s a snap to get
this kind of photo at a resolution high enough to
produce a huge print. With a print resolution of 200dpi,
as used by Lightjet printers, I would theoretically
be able to print this image 32” wide. However
it’s common to get good prints that large from
a file produced by a single-exposure with a 6mpx camera,
so we should be able to do better here. As this file
has over twice the pixels, it should make a very respectable
60” print.
Even though this is a combination of three horizontal
photos, the FoV is only 25° as the shots were
taken with a 640mm (35mm equivalent) lens. |

The
Sturt’s Desert pea flower is very long and narrow,
which makes it an obvious choice for the panoramic
treatment. This image consists of three vertical exposures
with a 100mm macro lens and some fill flash.
I lay on the ground with the side of my camera resting
on the dirt, then tilted the camera to make the three
exposures. Using that technique the lens wasn’t
rotating anywhere near the it’s nodal point,
I got away with it this time because there are no
areas at the exposure junctions that include both
near and far objects. Therefore parallax is not an
issue.
When
the subject is this close however, not rotating around
the nodal point will often cause the images to be
all but un-stitchable. |

I
discovered this tree while exploring Redbank Gorge,
but didn’t know how to photograph it. It was
growing on the edge of a cliff and there was no way
I could get further away, so I just made four exposures
as I panned along the trunk and up to the branches.
Apart from ensuring that I had a reasonable overlap,
I paid no attention to the normal rules of rotating
around nodal points and keeping the camera level.
Because of my “poor” technique it’s
impossible to create a straight photo, but I quite
liked the shape created by my panoramic software as
it tried to make sense of the data it was given. |

With
this image I had the same problem as with the ghost
gum at Redbank Gorge, that is, a wide subject and
a narrow ledge from which to shoot.
I
took a series of five horizontal exposures starting
at the top right, and working down to the bottom left.
After stitching I had a similar-shaped image to Figure
3, but this time I decided to square the edges off.
Having
done that I played with ideas to put my odd-shaped
image back in the square. After many ideas I settled
on a background that is a desaturated version of another
panorama taken shortly after, from the opposite side
of the waterfall. |

Who
would have thought a grasshopper would be suitable
fodder for the panoramic treatment? This shot has
an FoV of only 15°, not exactly a typical wide
panorama.
Why
is this image only 1904 pixels in height, when my
camera has a sensor that’s 2048 pixels vertically?
If you look at figure 5a you will see that I goofed
a bit with the alignment, and therefore had to crop
the image. This is something to watch out for with
all panoramas, misalignment will cost you pixels,
and pixels are one of the main reasons for using this
technique in the first place. |

I
know I said to think outside the square, but was talking
figuratively, not literally. This image, taken of
the Diamantina River at Birdsville, illustrates a
quick and dirty approach to panoramas. While still
half asleep I peered from the back of the FWD and
noticed the light, with no time for tripods or anything
I grabbed my camera, jumped from the car, and made
two hand-held horizontal photos, one for the top half
and another for the bottom. Seconds later the moment
had passed. This photo didn’t even need special
stitching software; because it has a large black area
through the middle, it was just a matter of combining
them manually along that line. |
