PowerPoint: Colorized Microphotographs of Snowflakes by Rick Doble

Over 30 colorful photographs of snowflakes, taken through a microscope, are included in this show -- work that has been used in a variety of schools for about 15 years. This PowerPoint show also explains how the black and white microphotographs of snow crystals by W.A. "Snowflake" Bentley in 1885 were converted to colored images. Using a technique similar to staining, Rick Doble colored the original Bentley images (in the public domain) to bring out the structure of the crystals. Doble explains his process in this presentation along with a lavish display of his colored snowflakes. These colored photographs have been widely used in elementary schools and also at the college level. They have also been featured in libraries and in the national media. Documentation about these mentions are included at the end of this presentation. Permission is given to educators and non-profit organizations to use these images, as long as the artist is credited.
