How can I maximize depth of field in close-up and macro photography?

I shoot with a Nikon D40X and currently have only the kit lens. I’m considering either a macro lens or extension tubes for close-up photos of bugs, fungi, and flowers, though I don’t need full 1:1 magnification. What techniques help get the greatest possible depth of field in close-up or macro shots?

Use focus stacking for static scenes; a small aperture and matching combination of ISO/lighting for scenes with moving elements. Focus stacking is more time consuming, but preferred because small apertures will introduce diffraction.
When photographing flowers outside, you might want to build a temporary wall to block wind so your flower would be static.
Using shorter focal length also helps, but due to closer distance it makes lighting more difficult and may scare your model.

Depth of field gets very shallow as you focus closer, so there’s no single gear choice that solves it completely. The main ways to increase it are:
- Stop down to a smaller aperture, while balancing ISO and lighting as needed. This helps, but very small apertures can soften the image due to diffraction.
- For static subjects, use focus stacking: take multiple shots focused at slightly different distances and combine them. This is often the best way to get more of the subject sharp without relying on extremely small apertures.
- Keep the subject still. Outdoors, even slight movement from wind can ruin close-up sharpness, so shielding flowers from wind can help.
- A shorter focal length can give more apparent depth of field, but it requires getting closer, which can make lighting harder and may disturb insects.
For bugs, fungi, and flowers, the best approach depends on subject movement: use focus stacking for still subjects, and use a smaller aperture plus enough light for moving subjects.
