My Equipment and Photographic Techniques
I started seriously taking photos of Odes
in early July of 2008. This page is representative of these efforts. My gear
includes a Nikon D90 and a Nikon D60. I usually shoot with either a Nikkor 105
mm VR Macro or a Nikkor 80-400 mm VR Telephoto zoom lens and shoot with integral
flash. The 80-400 mm stays on the D90, and the 105 Macro stays on the D60. Most of the dragonfly shots are taken with the long lens, most of the
damsels are shot with the short one, although I get lucky from time to time and
can shoot them all with the Macro. I use the integral (pop-up) flash for
most shots, and recently have switched to mostly using the manual settings on
the camera, shooting (except in extremely bright or dim light) at ISO 800,
Shutter speed of 1/200th of a second, and F stops ranging from F11-16. I
almost never use a tripod anymore. If the light is really bright (and in
the right position), I may
not use the flash, and allow a faster shutter speed . . . or I may still use the
flash, and just shoot at a much higher F-stop. Some of the shots taken prior to May of 2009
and all shots taken before July of 2008 were taken with a Nikon D50. Some of
the early July 2008 (and earlier) shots were taken with the D50 and a Sigma 105
mm Macro, and many of the 2008 dragonflies were shot with a Sigma 135-400
telephoto zoom lens, but I've since replaced those lenses.
Shooting flying dragonflies takes a different set of techniques.
First, I shoot with the lens set on Manual Focus. Second, I
set the shutter speed very high - at least at 1/1000th of a second,
usually faster (1/2500 - 1/1250), depending on the light and the
type of insect - slow, fluttery flight can be captured with slower
shutter speeds than rapid flight or a hovering insect. I
usually set the camera on "shutter priority" ("S" on the Nikons) and
allow the F-stop to be set automatically. However, when the
dragonfly is against a dark background, the result is usually
unsatisfactory as the dragon is overexposed. In these cases, I
have to set both shutter speed and F-stop manually - usually several
F-stops higher than the camera's automatic setting - this is trial
and error. Finally, I set the camera to shoot at high speed,
multiple frames per second so that I can hold down the shutter
button and let the camera fire away.
Getting things in focus: If the dragonfly is hovering,
it is usually pretty easy to get it into general focus.
However, if it is flying it is a lot harder, but there are a few
things you can try. First off, don't try to stand too close to
its flight path - it is a lot easier to get a mid-range insect in
focus because your lens's field of view is larger. Second, try
not to aim at a flying bug with a complex backdrop like bushes,
trees, etc. You generally lose it against the bank - they are
a lot easier to see against the sky or water (uncomplicated
background). If it is flying a regular beat, patrolling back
and forth, I usually pick a spot in its path as it approaches, and
get that spot in focus, and then turn the manual focus back as it
approaches to try to keep it in focus, firing off photos the whole
time. This usually works until the bug recedes, at which point
I usually loose it and have to start over again. With an
erratically flying insect, all bets are off and you just have to try
to get it in focus as best you can. With common species, I
don't usually try, but sometimes something rare comes flying by and
you have to give it a shot. Finally, take a lot of photos, it
takes a lot of misfires to get a gem!
Below are 30 shots taken of a Straw-colored Sylph (Macrothemis
inacuta) in flight in August of 2009. Of the 35 shots
taken, only 4 were deemed in sharp enough focus to save.
