What is Macro

Macro is a term to describe a specific type of close up photography. Close up photography really mean anything that is closer in appearance than that of which the human eye can see. To relate photography (35mm film or FX digital) to the human eye we need to know about focal length. The focal length is a distance in millimeters shown on a cameras lens. Such as a 24-70mm f/2.8 lens, this means the lens is capable of any focal length between and including 24mm – 70mm (24, 25, 26, 27, 28, 29, 30, 31,… 64, 65, 66, 67, 68, 69, and 70). The human eye is equivalent to the perspective of a 50mm focal length on a 35mm film or FX digital SLR (Single Lens Reflex) however lacking the peripherals that our eyes have. With this in mind close up photography is anything closer in than what the eye sees and enlarges beyond true life size. Macro or Micro photography takes this a whole step further. True Macro photography creates a 1:1 ratio from reality to capture plane. If you were to lay our 35mm film or a FX digital sensor on the ground and place a blade of grass on top of it, that is 1:1 ratio. It is an exact size reproduction from real life to the image capture plane. That is why macro photography makes things like plants and bug larger than life.

The images here are close up and near macro images although few are true 1:1 ratio macro photography. All images were captured with my Nikon 105mm f/2.8 VR Macro lens.
