What is Macro Photography?
Macro photography is officially defined as photography where the image on the sensor is equal to or greater than life size. For our purposes we will consider any photo that we intend to show or print equal to or greater than life size as a Macro.
Who uses Macro photography?
It is used to capture finite details of a subject to allow viewing them without magnification. Persons selling small items, entomologists, bug lovers, doctors, inspectors, botanists, etc. all have uses for macro photography.
How do you shoot Macros?
1. A “point and shoot” camera with macro capability. Many point and shoot camera take excellent macro photographs. I used a canon S5IS to take a lot of my favorite macros.
2. An SLR camera with a ”macro” lens. Macro lens can be prime (single focal point) or zoom (multiple focal points).
3. An SLR camera with extension tubes. These tubes mount between the lens and the camera to move the standard lens farther from the sensor, which has the effect of magnifying the image on the sensor.
4. An SLR camera or point and shoot with Macro filter(s). These filters mount on the end of the lens farthest from the camera and are, in effect, merely magnifying glasses. The more expensive, the better. Multple lens versions reduce color aberrations.
5. An SLR camera with a standard lens mounted and another lens mounted in reverse. You have to buy a reversing ring to do this.
a. Reversing ring – no electronics, This method does not control the second lens in any way.
b. Reversing ring with wiring. This more expensive option includes wires that connect the second lens to you camera electronics.
Where are macros taken?
1. Macros are taken either in the field where the environment must be compensated for.
a. Light needs to be very bright
b. Wind affects both camera and subject
2. Or, they are taken in a controlled environment where light, wind and subject are under your control.
Tips and techniques:
Use a tripod whenever possible.
Use remote release or timer
Control lighting as much as possible
Use exposure compensation for very light or
Practice the kinds of shots you plan on taking
Consider the inherent narrow depth of field when taking macros:
Align subject to keep all key parts in focus (if desired) i.e. parallel to the lens. Having subject perpendicular can result in an interesting shot that blurs part of the subject.
Decide what you want to be in-focus and manually focus on that or use the correct focus point in your viewfinder for auto focus.
APERTURE: The wider open the aperture the shallower the DOF. For greater DOF, use narrower aperture, such as f11 to f16.
Take care to choose a composition that provides a complementary background in tone and color.
FOCUS Be accurate with your focus. Choose the appropriate point and use manual focus for accuracy.
