This is a genre that some photographers get hooked on and it particularly attracts people with a scientific bent, because it is all about making discoveries. Most new-generation cameras will enable you to see your object at a ratio of 1:1 – that is, the object at its real size. If your lens won’t focus this close, you can buy either a macro lens or a close-up filter to attach to your existing lens.

AUTUMN LEAF

Close ups focus our attention on something that we don’t usually notice, in this case the beautiful structure of this leaf. Many modern cameras are able to get this close without a macro lens. 1/15 second at f11, 55mm macro, 200 ISO. GH

THE MACRO LENS

This is a demonstration of how I photographed the autumn leaf, using a 55mm macro lens. The selected portion of the leaf is life size, and it is backlit by a lightbox – a great method of shooting translucent objects. GH

POCKET WATCH

I shot this pocket watch using backlight from a window and my 55mm macro lens, with the camera on a tripod to prevent any camera movement. As we get closer to a subject we have an increasingly shallow depth of field, which means that on a picture such as this the lens must be stopped right down to a small aperture to maintain sharp detail over the area of interest. That requires a slow shutter speed to achieve a normal exposure, hence the tripod. 1 second at f16, 55mm macro, 200 ISO. GH
