1 Although many lenses enable you to get close-up shots, only a true macro lens will give you 1:1 life-size images. If you’re on a budget, close-up diopter lenses (essentially magnifying ‘filters’ that screw onto the front of the lens) do a good job.
2 Depth of field is crucial at close focusing distances, as it can be measured in mere millimetres. A depth of field preview button is a definite advantage for close-up and macro photography, as it will enable you to see precisely what will be sharp and what will be blurred before you take the picture. To maximise depth of field, try to position the camera so that the back of the camera is parallel with the subject.
3 Use manual focusing for macro shots; focus first, as this sets the magnification, then nudge the camera or subject backwards and forwards to fine-tune the sharpness.
