If there is one thing that I like about macro and close-up photography it’s that no matter where you are right this moment, there is a fascinating subject waiting to be shot. Not many other kinds of photography can make that claim. Photographers that enjoy shooting portraits are dependent on a model to shoot. Landscape photographers exist in a seasonal world of changeable weather. A sports photographer has to go to where the sports are played and they too are limited by season.
No matter the season or the time of day I’d wager that a suitable close-up subject can be found within five or six feet of the chair you currently sit in. Photographers who pursue macro photography can find endless inspiration in the details and patterns that surround us. In exchange their photos reveal a tiny world that normally falls below our perception.
When it comes to exploring macro and close-up photography the good news is that anyone can participate. While a DSLR camera is preferred for close-up work, using a compact camera can be just as rewarding.
What is “Macro”?
So far we have used the words ‘macro’ and ‘close-up’ in this article. We also need to add ‘close-focus’ to our list of terms. These three terms will often get used interchangeably and that’s not entirely correct. Without getting too technical here are basic definitions of the three terms:
- Close-up is a photo term that describes filling the frame with the subject. A close-up isolates the subject from its environment. Any lens or any camera is capable of taking a close-up.
- Macro defines how large a subject is captured in the camera. Macro is expressed as a ratio like 1:1, 1:2 or 1:4 and it’s really pretty easy to keep it all straight. A 1:1 macro image is telling us that the image on the film or camera’s sensor is the same size as the subject in real life. If I take a 1:1 macro image of a dime using film and develop the film into a negative we would see that the image on the negative is exactly the same size as the dime in real life. If my lens maxes out at 1:2 macro the image will be ½ life size and so on. True macro lenses capture images at 1:1 ratio (some include 1:2 ratio too).
- Close-focus describes any lens where the maximum size of the captured image is smaller than the real life subject. Here we are talking about ratios of 1:2 or less (eg 1:3, 1:4 etc). Most zoom lenses are actually not macro lenses but close-focus lenses.
We will go over some of the more technical aspects in more depth in a future installment. For this article we will use the term ‘Macro’ in talking about this subject. Purists will just need to bear with us for now.

Some Tools of the Trade
Macro photography is so popular that most cameras have an exposure mode built-in to support it. If your camera has selectable modes you will find macro by selecting the icon shaped like a tulip. Selecting this mode on a compact camera can cause the camera’s lens to lock at the optimum length for close work. On a DSLR the macro mode only changes exposure meter settings and focus zones; selecting the mode won’t do anything to the mounted lens.
The most common DSLR lenses used by hobby photographers for macro photography is a tele-zoom lens; a lens in the 55-200mm or 70-300mm range. These tele-zooms tend to have a macro ratio of 1:3 or 1:4.
If the photographer doesn’t have a tele-zoom a basic 18-55mm kit lens or 50mm f/1.8 lens equipped with inexpensive Close-Up Filters will do the trick.
There are true macro lenses available for every DSLR lens mount. These are the lenses that offer a 1:1 or 1:2 image ratio.
We will talk in depth about the equipment and accessory options that can take macro photography from enjoyable curiosity to passionate pastime in future installments. For now we have three assignments designed to get us thinking in terms of small, tiny and details.

For these assignments use your camera in the Macro Mode setting. If you are shooting a DSLR and have a tele-zoom lens you might wish to have it mounted to the camera.
For each assignment take 10 images over about 15 minute’s time; make sure to use all of the time and take no more than ten images. Set your lens length for maximum magnification and do not change the setting. Learn to move yourself and the camera toward or away from the subject in order to create your composition or achieve focus.
Assignment number one is an old favorite. If you have an old Hula-Hoop you’re set, otherwise fashion a ring about 30 inches across out of old garden hose, cardboard or another semi-rigid material. Take your ring to a garden spot and give it a toss. Wherever the ring lands is where you take your macro pictures. You may only photograph objects within the ring. Our goal with this exercise is to learn to see small subjects and isolate them into images. (Tip: don’t toss your ring onto empty open lawn! It’s OK to aim.)
Assignment two is fairly basic. Find a toy or model no larger than an inch or two and place it in the middle of a white sheet of paper. Have the paper and your object setup close enough to a window for illumination. Moving your subject as little as possible take your shots as described above. Our goal is to get a feeling for how the subject changes as we move our camera and change our viewpoint.
The third assignment is about discovery. Walk into any brightly lit room and find ten macro shots to take. Do not move or touch any object that you photograph. Your flash will probably not do you any good so the bright room is necessary. Take macro shots of ten different objects. (Tip: for this exercise I like to use my kitchen)
