Photography is often seen as an expensive hobby, but here’s a way to create a lot of fun for very little money: a macroextension tube you can make for less than $5 worth of materials. it against your camera body, you can take photos up close. In theory, the farther away from the camera you hold your lens, the highermagnification you get. The problem is that the “air” between the camera and lens element can’t have any light leaking in. Furthermore, there cannot be any lens movement when you take photos, as thiswill result in blurry photos. The solution? A macro extension tube, which holds the lens and shuts out light. Extension tubes and bellows can be bought, but that’s definitely more expensive andprobably a lot less gratifying than building something yourself. For our tube, we’ll use a Pringles can,

Macro Tube Theory
The concept of a macro tube is as old as photography itself. Normally, a lenstakes incoming parallel light and focuses it down onto the film or imaging chip. By turning the lens the wrong way around, the opposite happens: light focused in on a small area is refracted to becomemore parallel. With the lens in its wrong-way configuration, either by using a reversal ring or by just holding
