Focus stacking combines multiple component images that each have a slightly shifted focal plane

Preparing the Subject

The amount of thought and time you put into preparing your subject before you even take your first picture is what makes or breaks the final result of the focus stacking process. A high-quality composite result naturally depends on the series of component images that are as perfect as possible.

At a magnification level of 1:1 with an aperture stopped down to f/32, the depth of field encompasses only the first few millimeters. Everything else is blurry.

Dirt and dust on the subject can completely ruin the entire effort. Unfortunately, problematic particles of debris on a tiny subject often aren’t visible to the naked eye. When you’re getting started with a project, always take a few test images up front to closely evaluate how optimal your subject appears. If you skip this step, you run the risk of stacking not only layers of sharpness, but also dust, which leads to a retouching process that is not justified by the end result.

A blower designed to clean the sensor and a paintbrush are usually the only tools you need to tidy up your subject to avoid this fate. When photographing living objects such as insects or parts of plants, take extra care not to harm your subject while you clean it up.

As long as they’re not water soluble like salt crystals, most minerals and geologic specimens can be cleaned with lukewarm water and a fine, soft brush. But even with crystals, you may be working with delicate structures that can’t withstand any direct contact, so exercise caution.
