A while back, I went on the auction site (aka feebay) and paid a few dollars for a Nikon PB-5 bellows. Basically, while dedicated Macro lenses (such as the Nikkor 105 mm Macro) let you take ‘life size’ pictures (1:1 ration of the real and virtual picture), a bellows extension lets you blow it up even further. In my case about 4:1, i.e. a 1/4 inch in the real world projects as one inch on the sensor/film, making for some really blow up shots. This is the way I took a picture of the seashell a few posts below, here are some more examples. It is fun, but cumbersome, as you have to focus well - even at small apertures the DOF is shallow, refraction becomes a problem and the object sits right in front of the lens, making lightening challenging. These were taken with an old 55mm Nikkor f3.5 mounted and the bellows almost fully extended.
