Zoom in to get detailed shots of actions, especially when performing smaller or more intricate tasks.

If you zoom in too far, your readers may lose track of what they're looking at. Try to leave enough reference points in the photo so that readers can orient themselves.

In this example, the black "bullet" chamber is a good reference point. Without it, the action is still clear, but the location is not.

For very close shots, your camera may have trouble focusing. Switch to Macro mode (usually denoted by a flower icon) for extreme close-ups.
