Macro photography experience with extension tube (Bangla)
Macro photography or taking photos of things under high magnification–is really fun. An extension tube is an attachment that goes between your camera body and your lens. It’s not an optical element, so there is no glass involved. All it does, is get the lens further away from the focal plane. Now, the practical upshot of this, is that your minimum focusing distance gets smaller. So, with an extension tube, you can get closer to your subject; you can fill the frame with more of it, and still achieve focus.
