Advice on macro photography
Which lens do you need?
In macro photography, you want to record your subject as true to nature as possible. The magnification factor of a lens plays an important role in this. This ratio is shown on the front of the lens. Most macro lenses have a magnification factor of 1: 1. This means that the sensor is the same size as the subject you want to photograph. This allows you to photograph a small subject at full size. If you choose a lens with a variable focal length then this ratio is often different. The magnification factor can then be, for example, 1: 2. Then your subject will be registered twice as small.
When taking a macro photo, you are often so close to a subject that little light passes through the lens on the sensor. This makes an objective with a high light intensity of great importance. Therefore macro lenses have a large aperture of 2.8 or lower. An additional advantage of this is that you create a small depth of field in your photos. This means that your subject will come loose through a blurred background. Zoom lenses with a macro function are often less bright and have a variable diaphragm. This means you capture less detail.
Each lens has a minimum focusing distance. It indicates from which distance you can focus on a subject. A macro lens has the shortest possible focusing distance, so you can capture all the details.
What should I pay attention to?
Use a tripod
When making a macro photo, a tripod is actually a must. With a tripod you can be sure that your camera is stable. You also want to have a tripod that can lower to the ground so that you can photograph insects, for example.
Although a bright lens has already brought you a long way, it often does not take enough light to make bright macro photos. A flash comes in handy here. You can provide the right lighting with special macro flashes.
Macro photography offers you the chance to capture the details in everyday objects. Therefore, you should focus on research in your own environment. For example, a garden will already yield enough beautiful photos. Try playing with composition and focusing. You can also frame a subject in different ways. All attention must go to your topic. So the background must not distract too much. Ultimately, such a minimalist photo often yields the strongest picture.
