Light scanning photomacrography

This method overcomes the limitations of conventional macro photography, which typically only keeps a portion of the subject in acceptable focus at high magnifications.

The principles of LSP were first documented in the early 1960s by Dan McLachlan Jr., who highlighted its capability for extreme focal depth in microscopy [1] and in 1968 patented the process.

[2] The technique was revived and further developed in the 1980s by photographers such as Darwin Dale and Nile Root, a faculty member at the Rochester Institute of Technology.

[3] In the early 1990s, William Sharp and Charles Kazilek, both researchers at Arizona State University, also published articles describing their technique and system setup for capturing SLP images.

[6] A typical LSP setup includes: In 1991, Sharp and Kazilek described their SLP system that used three Kodak Ektagraphic slide projectors with zoom lenses to create a thin plane of light.

Other applications include forensic science, mineralogy, and the imaging of fractured surfaces and parts [8][9][7][10] Enthusiasts and researchers have contributed to the development and accessibility of LSP by creating and sharing DIY guides.
