Here is a step by step guide to taking tack sharp macro photos. Learn how to get close and make great photos.Macro photography opens an entirely new world of image making. The closer you get, the more you’ll see things you never knew existed. Little details become primary compositional elements. Small parts of the whole take on an immensity that otherwise go unnoticed. It’s an investigation into the miniscule and the deeper into it you explore, the more you’ll find. The most commonly photographed subject for macro photography is flowers, but there’s very little out there that isn’t fair game.
How To Get Close:
a) The most common tool, but the most expensive, is a true macro lens. If you go this route, I encourage you to get a longer focal length version as the wider ones get you so close to your subject, it makes it difficult to use auxiliary flashes to modify the light. Additionally, if you get into photographing insects, the longer focal length gives you a greater working distance so you won’t scare the bug away. The longer ones range in the 180-200mm range.
b) Extension tubes are commonly used as they are a less expensive alternative. They fit between the camera body and lens which in turn allows any lens to focus closer. The bigger the tube, the closer the lens can focus. They contain no glass elements.
c) Tele Extenders are a good alternative as they increase the focal length of the lens by a factor of the specific extender: 1.4 / 1.7 / 2.0. Extenders are used less often as they are not compatible with all lenses.
d) “Macro Zooms” - many zoom lenses claim to be macro but they do not have the close focusing capabilities of a true macro lens so be wary of a manufacturer’s claim.
e) Close up filters work well if you stick with Achromatic quality ones. They screw onto the front element of your lens making them very easy to use. When attached to a zoom, they provide great versatility as varying magnifications can be had based on the focal length that’s set. While not cheap by filter standards, they’re one of the least expensive ways to get into macro photography. They also provide excellent quality. Realize they can be only as good as the lens to which they’re attached.

How to Get Sharp:
Critical Focusing: Macro photography is all about magnifying the details in your subjects. Hand in hand goes the fact that because you’re magnifying the subject matter, you’re also magnifying any mistakes. A minute error in focusing makes the difference between a keeper or an image destined for the delete button. Focusing rails assist you in attaining critical focus as they allow the camera to move in precise increments. Alternatively, move the camera backward and forward rather than try to focus the lens. At the moment you see the plane you want sharp come into focus, press the shutter.
Stability: It’s essential the camera is held steady when making macro photos. This necessitates the use of a sturdy tripod. Again, in that you’re magnifying your subject matter, a small amount of camera shake is magnified into a big mistake.
Cable Release: Pressing the shutter can introduce movement. The use of an electronic cable release prevents this as the camera is fired without having to touch the shutter.

Mirror Lock Up: For subjects that are stationary or not impacted by the wind, if your camera has mirror lock up capability, I encourage you to use it. Mirror slap creates movement which in turn reduces the sharpness. If the mirror is locked in the UP position, there’s no negative impact.
Depth of Field: The more a subject is magnified, the less depth of field. If you need to extend the DOF, you need to stop the lens down. This translates to a slower shutter speed which may impact sharpness due to camera movement. Be cognizant of the required DOF so you’ll know how it may impact the outcome of the image. The use of flash or other means of adding more light can help alleviate some of the potential problems.

Selective Focusing: The use of selective focus gets into the creative aspect of macro photography. Long lenses placed very close to the subject and shot wide open are the norm. The effect is painterly as just a sliver of the subject is sharp. It works well with flowers. A benefit is some of the above concerns become less critical as fast shutter speeds are used and important DOF issues have less impact.
