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.

1. Colorized Snowflakes
by Rick Doble From a past exhibit: snowflakes with added color
based on the landmark work by W. A. Bentley
who was a pioneer of photomicrography and who
invented a method for photographing frozen ice crystals in
1885.
Widely used by teachers and reported in the media -- see citations at the end of this presentation.

These images can be extracted from this PowerPoint presentation in a variety
of ways. PowerPoint allows each page to be exported in a number of file
formats. Find the EXPORT command and then save in the desired file format.
In addition Windows allows a simple way to screen grab an image. Press the
ALT + PrtSc(PrintScreen) top right to grab a window -- and then go into a
graphics editing program where you PASTE the screen grab -- at which point
the picture can be cropped, enhanced and then saved. There are also a
variety of screen grab apps that are part of graphics programs or available
separately -- many of these are free.

3. No Snowflakes Are Alike
Bentley discovered that no 2 snowflakes are alike. This
is particularly odd because virtually all hydrogen atoms
are the same and virtually all oxygen atoms are the
same -- i.e., the atoms that make up water.
Yet the frozen crystals they create in the form of snow or
ice crystals are different, even though the crystals
contain a basic similar (hexagonal) structure.
"...it's unlikely that any two complex snow crystals,
out of all those made over the entire history of the
planet, have ever looked completely alike."

6. Although each snowflake is different,
the structure of each is the same, i.e., hexagonal.
So this animated work of
several snowflakes overlaid on each other
creates an interesting pattern.

7. Around 1997, I developed a method for
substituting color in the black and white
photographs of Bentley because I thought it
could show the structure in a different way.
Years earlier I had learned from a scientist
that staining could bring out aspects of a
organism or crystal that could not be seen
otherwise.
The following pages
show my experiments with color and the
snowflake or ice crystal structure.

26. About My Work With Snowflakes
I made these snowflake images beginning
around 1997 before digital cameras became
widely available. As a photographer I wanted to
work with photographic images and also to
experiment. These public domain photographs
of Bentley were perfect since they reflected my
interest in patterns in nature (my first
photography book) and also my interest in
microscopic imagery -- having worked with a
microscope as a young boy.

27. About My Methods
My own method for adding color to these black and
white photos was to scan them and then separate
each image into 16 shades of gray. Then I
substituted a color for each shade of gray using the
palette ability of GIF files. This was a technique I
had perfected with the photographs of Muybridge
10 years earlier using a Radio Shack computer in
the 1980s.
When I started out, I substituted a dark color for a
dark shade of gray and a light color for a light
shade of gray. Later I became more adventurous
and played with the colors in a way that would
bring out the structure even more.

Used for lesson plans:
"As I was researching Wilson Bentley and snow to create lesson plans for Kindergarten
through 3rd grade who are participating in the Winter Wonderland project, I ran into a site
by Rick Doble. As part of his work, Rick has exhibits of snowflake images which he
digitally altered from Wilson Bentley’s snowflake pictures. This became the jumping off
point for the projects I did with my 4th & 7th Grade classes."

Snowflake pictures put up at a Belgian school site:
Dear Rick,
I'm going to do my very best to translate what I wrote on our website.
« By chance I found in the - indeed excellent - weekly "Clickx" an article about the website
of a certain Rick Doble. This "digital artist" occupied himself with editing (I have the
impression this is a poor translation for our word "bewerken", sorry; maybe "elaborating"
can do?) with color the photographs of the snowflakeman. The writer of this article putted
that those images were indeed very beautiful, but asked himself (we quote:) "Allright, but
what can you do with such a work of art?" Dear JDP, on this page you get an answer for
your question. The magnificent photographs of Rick Doble are a perfect illustration for the
text that I present my pupils. Internet: what it's all good for!»

Maine Association of School Libraries
One computer artist has taken some of Bentley's landmark snowflake photographs
and transformed them into stunning animations that are like crystalline light shows.
His name is Rick Doble, and his work may be experienced at
http://www.RickDoble.net/newsnow Work with your art teacher and your computer
teacher to learn something about Doble's artistic approach. Prepare a presentation
for a specific audience that incorporates these moving images.....the presentation
could be about art enhancement, about computer art, about Bentley's and Doble's
artistic goals, as an introduction to a scientific presentation on snow crystals, or other
approved topic.
About the 3rd Annual Snowflake Exhibit by Rick Doble:
Maine Association of School Libraries
Activity For Children:
Do you like Mr. Doble's snowflakes? Do you like them more or less than the ones
done by Mr. Bentley? If you could choose one picture of Mr. Doles to save for
yourself, which one would it be? Tell why. Save the picture to your disk to share later
with friends or the class. Look at your choice of favorite snowflake pictures by
Bentley. Compare it to some of the ones Mr. Doble has enhanced. Which do you like
best?

Major Announcement: Internet Minute
We're dreaming of a White Christmas, and while Nature may or may not cooperate
with our dream this year - we can see snowflakes as we never have on the net.
Rick Doble is an Internet Artist - An E-Artist, so to speak. Have you ever tried to
look at snow-flakes. It isn't easy, because they melt so quickly. Each little crystal
is believed to be unique - the molecules of moistures freezing with particular
beauty every time around its host mote of airborne dust. There are still photos,
and animations of snowflakes in Rick's online exhibit. It's a nice little thing to
check out, to get you into the spirit of snow this season.

Digital Totem Poles and Other Stuff
Rick Doble is a digital artist who has invested his work with a great deal of thought.
His digital totem pole exhibit is a series of 10 high-quality abstractions. The images
and patterns are derived from the manmade and natural world. Rick lists the major
artists and artifacts that influenced his work. This is serious stuff, and very moving.
The site has several other online galleries of Rick's digital art, all worth visiting.
Don't skip the Third Annual Snowflake Exhibit. You can also browse Rick's written
philosophical musings on digital art and the nature of art in the 21st century. If you
think of art as more than just pretty pictures, this is truly a stand-out site.
