LET THERE BE LIGHT
The use of a single electronic flash on small creatures

By Jim Moerschel

 

Close-up photography in nature is both exhilarating and very challenging to create high
Quality images of small creatures. The first obstacle is being able to approach wary little
Denizens of our swamps, fields and forests close enough to fill the frame of our viewfinder.
Once that is accomplished, we are faced with depth of field and shutter speed issues that need
To be resolved. The primary problem is the quality of light, since we may be out and about


On days when the light is dull and also dim.
The solution to all these negative factors is to bring the main light source along with
Us. Our modern cameras also use modern flash units that automatically increase or reduce
The amount of light for proper exposure. Gone are the old days where close-up lighting was
Lots of trial and error (mostly the latter) and everything was manually calculated. The old
Manual method was excellent and to this day I still on occasion use it, but with modern cameras
And dedicated electronic flash units, close-up nature photography is much easier.
My camera setup is a Nikon N90s with a 180mm macro lens. I still use an “older
Generation” Nikon SB 24 electronic flash with a “soft box” diffuser mounted on the front of the


Flash. This diffuser spreads the light source evenly which gives the image a nice look.
Now that we have our equipment ready, then we have to make a decision on the camera
Settings. My preference is to shoot in aperture priority mode. This gives me control over
My depth of field. The depth of field is so important in close-up shooting, because as
Magnification increases we have a decrease in depth of field. Thus, lining up the subject to
Include most of the head and body in sharp focus means trying to get as parallel to the
Subject as possible. Sometimes we may want to shoot with a large f-stop, which will give us
Very limited depth of field, but most of the time it will be better to stop the lens down to f11
Or f16. These apertures will give the photographer more depth of field, but while doing
Close-up photos, this will still be very limited. The camera will set the shutter speed to
Correspond with the f stop down to f16.


The most important part of the creature (subject) to be sharp is the eye. Eye sharpness
Is critical for the success of the final image and cannot be emphasized enough. If the eye is
Out of focus, it doesn’t matter that most of the rest of the head and body are razor sharp. The
Photo is a failure. So it is a good idea to always focus precisely on the eye of the tiny subject
And then make the image. If the eye is nice and crisp, the photo of the creature will appear sharp
Even if most of the body is soft.
Now that we have our equipment ready and a guideline of how we will make the photos,
Lets take a walk through the woods and visit our favorite pond. In summer months there
Are lots of frogs, salamanders and dragonflies that inhabit these watery places. There are always
Frogs sitting along the edge of my woodland pond, so we will find one and go on the hunt.
Today I’ve found one sitting in the shallows facing the pond edge. This won’t be
An easy stalk. It rarely is! I try to walk as slowly as possible and get to a point where the
Frog still will tolerate my approach and then carefully get down on all fours and begin inching
Closer. When I’m in decent range for a full body photo I take the shot. This way I’ve got
One good photo in “the bank.”
The day is overcast and the light is dull and very dim. My first photo shows this.


Then the flash unit is turned on and I focus and shoot. The second photo shows a dramatic
Improvement. The colors jump out at the viewer, the background reeds and water take on a
Colorful look. The entire scene is completely changed.


Now it’s time to creep ever closer. This is tricky. One sudden move and the frog will
Dive into the pond. With the thought that I’ve got a good image already should the frog take
Flight I reach forward until the head is tight within the viewfinder frame and press the shutter.
The flash fires and the frog dives in. Got him!!


On the final head shot, I made sure I was focused right on the eye and with the lens stopped down to f16 I got what I wanted. There are lots of small creatures in every woodland
And lots of adventure for those who stalk them. Whether the day is bright or dim go out
Anyway and bring your own “sun” with you and have lots of fun.

I wish you good luck with your image making.
