Hack 22 Get Super Close
Digital cameras have macro capability built right in. But what if you want to get real
close? Here's how to get a bug's-eye view of the world .
Since the early roots of photography, people have been fascinated with capturing the world
up close. Super close. Bumps-on-a-frog close. Most digital cameras come with a Macro mode
that allows you to get very close to your subject. Sometimes, this mode is simply called Close Up
and is denoted by a flower icon on your camera. Depending on your camera, close can be defined
as anything from 6 inches to 18 inches. But what if you want to see the very pores? This hack
will help you get started.
There are a few ways to get these types of startling shots. The first way is to buy a macro
lens that is designed specifically for this type of shooting. Unfortunately, these lenses are
often quite pricey. A second option is to buy extension tubes for your DSLR. An extension
tube is a light-tight tunnel that extends the distance from your lens to the camera body,
thereby increasing magnification ? the greater the distance, the more magnification.
But what if your digital camera isn't an SLR or doesn't take interchangeable lenses? The third,
and most affordable, option is to buy a close-up lens that mounts on top of your current
lens, the same way that filters attach. Some cameras have adapters for these auxiliary
lenses. But if yours doesn't, third-party manufacturers such as Raynox (
http://www.raynox.co.jp/index.htm ) have devised clever workarounds to enable this
capability on just about any digital camera. The advantages are that you don't have to buy a
whole new lens and that you can use the close-up lens with any camera, including an SLR.
This is the tool we're going to use for this hack.
2.8.1 Get the Glass
First, go down to your friendly photo dealer and see what type of close-up attachments are
available for your camera. I've had a lot of luck with the aforementioned Raynox lens, which is
well made, affordable, and readily available. Raynox makes a wide variety of goodies for all kinds
of cameras, including close-up accessories for digital cameras. The lens comes with an
attachment to help you mount it over your built-in glass. Turn on your camera and ? voilà!? you
have a super-macro digital camera.
How close can you get? Close-up lenses are described by a diopter number that indicates
how close your lens can get to the subject, in units of fractions of a meter. For example, a
lens marked +12 will let you get within 1/12 of a meter (or within just 8 centimeters). For
those of you inclined to use the imperial system, that's just over 2 inches away ? also known
as pretty darn close ! What's fun about all of this math madness is that these measurements
are based on the lens of your camera being set to infinity. If, like many cameras, yours has
the ability to focus manually, you can get even closer by using the close-up lens and its
built-in close-focusing setting.
2.8.2 Mount the Camera for Best Results
So now you have a close-up lens attached to the camera and are ready to shoot, right?
Well, almost. Shooting one inch away from a subject is tricky, because the lens has very little
tolerance for being even a little too far or too close to the object. If you move out of that one-
inch in-focus area, your object will quickly get soft. This means that to take really good shots
you need to mount your camera on a tripod.
In super-close-up photography, moving the camera to correct focusing is
easier than fiddling with your digicam's focusing mechanism. Many
used-camera stores carry focusing rails for just this purpose. You mount the
rail on your tripod and then secure the camera to the rail. Then,
just turn the focusing knob to move the camera closer or farther from the
subject in small increments. It really helps!
