Macro Photography, also known as close-up photography, is the photography of small objects. A macro lens is a lens that offers a magnification of either 1:1, (1x) or sometimes only 1:2 reproduction.
A macro is a simple program that automates a series of ImageJ commands. The easiest way to create a macro is to record a series of commands using the command recorder. A macro is saved as a text file and executed by selecting a menu command, by pressing a key or by clicking on an icon in the ImageJ toolbar.
