1. The main thing I'd like to improve on is getting consistently sharp images
with telephoto lenses, so I'd like to ask, What have you found to be the best
technique or combination of techniques to get sharp images with long telephotos
(without IS) and with slow shutter speeds? For example, using a 500mm +1.4x TC
(700mm) and 100 speed film, I find myself at 1/45-1/80s a lot of times. Of course
that's on a tripod, but still pretty hard to get great sharpness every time short
of using MLU.
I, for one, have never had great success using mirror lock-up and I never use a
cable release (though pal Tim Fitzharris uses one all the time when photographing
static birds. The simplest and easiest tip that I can offer is to push your 100
speed film one or two stops to gain additional shutter speed. (I push nearly
every roll of film that I shoot.) I push Velvia one stop to EI 100 and push
Provia F 100 one stop (at EI 200) and two stops (at EI 320).
As for technique, I am a big believer in pressing your face to the back of
the camera while holding the camera firmly with your right hand. Over the course
of my career I have used my left hand in various ways to stabilize the big Canon
lenses that I use (and do so today even with IS lenses). Long ago, I simply rested
my left hand atop the lens barrel but do not use that technique any more. Now,
I use the following technique: With the palm of your left hand pointing skyward,
put that hand under the front of the lens plate and grab it with the last two
or three fingers. (I've always loved extra-long lens plates.) With your thumb
and index finger, push up forcefully on the lens barrel from below. (No matter
how sturdy your tripod head and big lens are, there will always be some play here.)
You may have to frame a bit low so that when you "take the play out" you wind up
with the desired framing. Hold the camera firmly in your left hand and press
your face against the camera back and you will be able to make sharper images
at slower shutter speeds than ever before. This will be true even for users of
Canon IS lenses, as good technique simply allows you to push the envelope further.
2. I am thinking of buying a macro lens for my Canon body. Have you
used the 180 macro and is it really as sharp as it is reported to be? Is there
a better Canon macro lens on the market?
I own and love the EF 180 macro lens. I never test lenses; I just use them and
see how the images look. And guess what? Every single Canon lens that I have
ever used has made sharp images when used with proper technique, but the 180 macro
lens is particularly sharp. Additionally, I love the longer focal length macro
lenses for the working distance that they provide. I often use either my 500mm
or 600mm IS lenses with two 25mm and one 12mm extension tubes in combination for
photographing large flowers and large insects. Back to the 180 macro, serious
close-up photographers should check out Canon's macro twin light--it yields the
most beautiful soft light imaginable--the images look as if they were made in soft,
diffused sunlight.
3. Do you use Provia F100 or Velvia most often for your images of birds?
It is funny that you ask that now as I just returned from my annual pilgrimage
to Bosque Del Apache NWR in New Mexico where I used my brand new EOS 1D digital body
for most of my photography... In any case, the films that I use are Velvia pushed one
stop to EI 100 and Provia F 100 pushed one stop (at EI 200) and two stops (at EI 320).
I rarely use either film at normal (the rated ISO). On most trips in the past three
years, I use them in about equal proportion, using more Velvia in sunny locations like
Florida and more Provia in darker places like the Pribilofs.
Though the choice of which of these two great films to use is often a difficult one,
here are my thoughts:
I use Velvia:
- As much as possible. For my taste, its brilliant color palette is simply unsurpassed.
- In low light and on dreary days when I am NOT using flash.
- In warm light (when I have sufficient shutter speed, and subject movement is not an important consideration).
- From 1/2 hour to roughly 1 1/2 or two hours after sunrise on clear mornings and from 1 1/2 to
2 hours before sunset on clear afternoons.
- Right at sunrise, and then again right at sunset (again, when I have sufficient
shutter speed, and subject movement is not an important consideration).
I use Provia F100 often pushed 1 stop to EI 200 or 2 stops at EI 320 (Yes! Rate the
film at EI 320. Compensate as you normally would, then tell the lab to push the
film 2 full stops (not 1 2/3 stops):
- On dreary days when I am using flash. I have noticed over the past few months
that many of my fill flash images made with this film are overexposed. (This happens
when using fill flash exactly as I would when using Velvia: -2/3 stop for middle
tones subjects, -1 or -1 1/3 for white, yellow, or light toned subjects, -1/3 stop
for dark subjects, and 0 or even +1/3, for very dark or black subjects. I will
begin experimenting with using less fill flash on my upcoming SW Florida IPT trip.)
- In warm light when I need extra shutter speed and subject movement might be a consideration.
- At normal (ISO 100) two hours after sunrise or before sunset on clear days. Provia
F100 handles the contrast in bright scenes better than Velvia.
- In extremely low EV situations where Velvia simply has no chance to even register
a flock of birds in flight on the film.
- Often, when I am using the 600 IS/2X TC combination, or when stacking teleconverters.
Remember, however, that film choice is strictly personal.
4. One of my nemeses has been trying to shoot birds that are both dark and bright
white - trying to maintain detail in both has been virtually impossible. What would
be the best way to approach these types of subjects? For example, a male Mallard
which has the greens, blacks, browns and some whites - or a Black-necked Stilt with
almost a true black and white coloration. Should I expose for the area with the most
coloration, whether that be dark or white?
First tip here is to try to work in anything but harsh sunlight when contrast is
high. Working on cloudy or cloudy bright days is ideal, and using fill flash in
these situations helps to. Working in early morning or late afternoon on clear days
can work equally well or better. Choosing a low contrast film like Provia F 100
helps, and digital captures have far greater latitude than film so going that
route is another option. When using color slide film, most folks advise you
(at all times) to "expose for the highlights" (to prevent overexposing them).
I am just about the only one who teaches folks to "expose for the blacks (or darks)
when the details in the blacks (or darks) are vitally important to the image
and the white (or highlight) areas are small and the lack of detail there will
not impact the image significantly. In these cases you are "giving away the
whites" a bit in order to attain more detail in the blacks or darks. If there
are significant areas of white or very light tones, then you must of course avoid
over-exposing these highlight areas by choosing and exposure that is 2/3 to 1 full
stop darker than the correct middle-toned exposure. Those who understand exposure
theory know that the correct exposure for darks and blacks is 2/3 to one stop
lighter than the correct middle-toned exposure. If you are interested in understanding
exposure theory see the Exposure chapter in The Art of Bird Photography:
