How do you set up your camera for macro photography?
Aperture
The aperture is one of the most important factors of making a good macro photo. A good macro photo usually has a little depth of field, which you create with a large aperture. A low aperture number means a large aperture. How you set the aperture depends on your camera. If you want a small depth of field, you should choose a number starting at f/5.6. Some cameras have a maximum aperture of of f/1.2. Feel free to experiment with these values.
Shutter speed
If you photograph with a large aperture, that means that you're working with a large lens opening. You allow the sensor to capture more light that way. If your photos become overexposed, you'll want to adjust the exposure with a faster shutter speed. This gives your camera less time to capture the light. Note: with macro photography, it's important that you always work with a high shutter speed to prevent motion blur.
ISO
Do you work with a high shutter speed and a large aperture? Your photo might become too dark. With a higher ISO value, you ensure that the sensor becomes more sensitive to light and captures more light as well. With a higher ISO value, you also increase the chance of blur. Depending on your camera, you'll see some blur at 400 or 800 ISO. This means that increasing your ISO value should be a last resort to adjust the exposure.
Focus
If you work with a small depth of field, you're supposed to focus the camera on the right part. With macro photography, you photograph objects from a short distance. Cameras often struggle to focus automatically because of that. That's why it's best to use the manual focus. Switch to 'MF' (manual focus) on your camera. You can usually find the button to do that on the lens. After that, keep an eye on your subject and rotate the lens ring until the subject looks sharp.
Zoom
With a special macro lens, you can take the best macro photos. That's because these lenses often have a short focal distance, a large aperture, and a fixed focal point. A short depth of field allows you to take clear photos of your subject from a short distance. If you have a zoom lens instead of a macro lens, try to zoom in as little as possible. If you zoom in completely, it's often not possible to use a large aperture. So simply try to get as close to the subject as possible.
