Easy, budget macro.

Macro or close-up photography is accessible without investing in a pricey macro lens. The first three articles in this series covered techniques for inexpensive macro-level results: close-up lenses, reverse rings, and extension tubes. In this article, I offer suggestions for achieving great-looking results using any of these three techniques.

Choose Your Depth of Field

Depth of field is a term that refers to the area of the image that is acceptably sharp and in focus. Depth of field is a function of many things. Our interest is in three factors. These are aperture, the distance between the camera and the subject, and the orientation of the subject relative to the camera.

Aperture has a direct influence on the depth of field. A wide aperture (smaller f number, such as f/1.8) creates a shallow depth of field. Areas of the image outside of the zone of sharpness fall out of focus quickly. Wide apertures can be used to create bokeh – unsharp sections of the image.

A narrow aperture (larger f number, such as f/22) creates a deep depth of field. The majority of the image is in focus. Narrow apertures are often used by landscape photographers to capture front-to-back sharpness throughout an image.

The distance between the camera and the subject also influences the depth of field. Generally, the closer that you are to your subject, the narrower the depth of the field becomes. This is particularly important when using macro and close-up photography techniques where you need to be physically close to the photographic subject.

Penny shot with a Canon 50 mm f/1.8 lens and a full set of three, generic extension tubes (7, 14, and 28 mm). The plane of sharpness lies parallel to the flat of the lens. If the plane is not parallel the focus is quickly lost.

It is also important to consider the orientation of the subject relative to the camera. The depth of field can be thought of as a plane that is parallel to the camera lens. If you can orient yourself so that the subject is parallel to the flat of camera lens, more of your subject will be in focus than if it is at an angle to the camera. In the penny shot above, I tilted the camera lens slightly away from the parallel position. The loss of focus from right to left is obvious.

The flower photographs show how depth of field influences an image. Both were taken with the same lens (Canon 50 mm f/1.8), the same aperture (f/1.8), and the same technique (reverse ring). Both images have a shallow depth of field (wide aperture) and are close to the subject. The appearance of the depth of field is very different. The yellow flower (left) is sideways to the camera. Only the closest edges of the petals are within the depth of field and are in focus. The purple flowers center is shot parallel to the camera. The entire center of the flower is within the depth of field and appears in focus.

If you want more of your subject in focus use a narrower aperture. Increase the distance between yourself and the subject, and set the camera (and thus the depth of field) parallel to the subject. If you want less of your subject in focus, you can use a shallow aperture, get in closer to your subject, and orient the camera and depth of field perpendicular to the subject. Try it many different ways and see what works best for what you envision!

The Tripod: With and Without

It is possible to achieve acceptably sharp macro results hand-holding the camera. The majority of images in these articles were shot hand-held. If you have a stationary subject using a tripod will greatly improve the sharpness of your image. A tripod allows you to use longer shutter speeds. This helps you get crisper images in lower light. It also allows a narrower aperture to gain a deeper depth of field. The steadiness of the tripod will significantly reduce hand movement.

If available, also use the Live-View function on your camera to fine-tune your focus. Live-View lets you use your display screen rather than the viewfinder. Many cameras allow you to zoom in on a portion of the image to check the focus.

Without a tripod a good stance improves stability while hand-holding. Create your own tripod with your body by bracing yourself or your camera. In the diptych image below, I am using my elbows for support. The elbows in combination with my feet create a similar a three-point stability like a tripod. In the extension tube article, I demonstrated a similar human-tripod by bracing my elbows on my knees while shooting.

This three-point position allows me to lean in and out very slightly with the camera. I can manually find the exact focus that I want in the photograph. Focusing with body movement allows me to place the depth of focus exactly where I want it relative to the subject.

When you are hand-holding practice breathing slowly and pushing the camera shutter button gently, without imparting additional motion to the camera. (More tips on stance)

Play, Combine, and Find What Works for You

You can use extension tubes in combination with either a reverse ring or close-up lens for even more detailed images. However, the working distance between the lens and the subject is narrow and the depth of field is incredibly shallow. With the pennies below, I found it impossible to keep both Mr. Lincoln and the columns of his memorial in focus together, as the columns are slightly raised relative to the surface of the penny.

These pennies were both taken with a Canon 50 mm f/.18 lens and a set of three, generic extension tubes (7, 14, and 28mm). In the left-hand image a +10 close-up lens was added, and in the right-hand image the lens was instead reverse mounted.

Close-up lenses can also be screwed in to each other for greater magnification. I used both a +4 and +10 close-up lens for the snowflake image below. There is some distortion visible in the image particularly around the edges. I also found it more difficult to focus when looking through both lenses.

The final curtain

The varieties of subjects for macro and close-up photography are endless. I have tried to highlight a variety of them during this series. Flowers, insects, and falling water are perennial favourites, as are coins, Lego figures, and other small objects. Your imagination and creativity are your only limitations. Enjoy!
