  • Abstract

Basic Introduction to 3D Mineral Photography and a tutorial on how take stereo pictures of tiny objects using focus stacking techniques. Professor Emeritus, Howard "Cork" Hayden, shows how to take stereo photos using an inexpensive Opti-Tekscope digital USB microscope with a custom modified mount. He goes on to give a tutorial on using Helicon Focus software to create images that are in perfect focus at every depth level. He then finishes with a tutorial on Stereo Photo Maker software that is used to perfectly align the left and right images and output them to either stereo pairs or anaglyph images which can be viewed with red/cyan 3D glasses. This video ends with a slide show of his beautiful anaglyph images. November 13th, 2020.

Tahosa Territory: A Colorado Front Range Family
By Beth Simmons PhD (2008)

Many families living in Colorado trace their roots back to when “Tahosa Territory” (“Land of the Mountain People”) was the name first proposed for the land now called “Colorado”. The Rutherford, Rash, Neville, Mosch, Lahnert, Bangerter, and Herald families harken back to when the South Platte River bottomlands, the Buckhorn valley west of Loveland, and the Upper Boulder Valley in Gilpin County were undeveloped land.

Focusing on the family’s myriad achievements, this 55-minute movie, “Tahosa Territory,” demonstrates the history of Colorado through the lives of the members of a family now named Mosch.

A short clip from the program presented by Brian Busse at the February 2013 DGMG meeting.
