This image management system was first developed by Wernher Krutein in the mid 1970's after a decade of research in determining an ideal filing system to account for, research, retrieve, and refile large numbers of images. It has expanded its capabilities to the point where now virtually any image, of any nature, in any format, technical, human activity, or otherwise, can be easily and accurately categorized. This three letter based system called Fluid Logic allows full computerization, digitization, and cross referencing of every image in relation to a physical Slide Archive, and is infinitely expandable in the number of images within each category. There are 17,576 possible categories. The operating principle of Fluid Logic is "Within the enormous complexity, keep it simple".

Although it has evolved as an immensely practical way for filing slides, the category listings can be used as a guide for classifying and indexing almost any visual phenomena in the universe. The implications of Fluid Logic as a "visual reality indexing system" are enormous.

Through the use of this simplistic three letter alphanumeric system, we have researched the basic patterns of thinking from a layperson's view all the way through a highly specialized experts knowledge requirements.

We believe this to be the most comprehensive break down of the known visual universe. From the distillation of taxonomy to the inclusion of etherics, all that is known physical reality has been included in this work.

We have implemented this system into many corporations and individual picture collections. A workbook and video are available for purchase to those interested.

We are presently looking to team up with a software developer to create a digital archiving package that truly marries the physicality of picture collections with a digital retrieval system.


Fluid Logic is based on a three letter matrix indexing system. By using a logically and poeticly sequenced array of three letters, it is possible to group images according to their general subject matter and into more specific subsets as needed. The sequence and flow of these letters are chosen to match empirical reality.

The first letter is defined as the "Homing Categorical Letter" giving us a broad generalized logical sequence for finding the desired image. It is subject driven. The major categories for this series of letters are as follows:

A Animals: sequenced and grouped according to Phylum, Class, Order, and one of the
two primary environmental habitats, i.e. Aquatic or Terrestrial (see also O series)
C City-scapes, Architecture, Monuments, Houses, etc. (always by location-see maps & section III)
D Disasters: damage caused by Earthquakes, Fires, Storms, etc.
E Entertainment: Theater, Dance, Concerts, Performance, Painting, Sculpture, etc. (the Arts)
F Food: Farming, Agriculture (sometimes by location, see section III)
G Government: Politics, Flags, Courts, Lawyers
H Health: Healing, Hospitals, Doctors, Medicine, etc.
I Industry: Production and Manufacture of Goods
K Knowledge/Education: Colleges, Libraries, Schools, Students, etc.
M Military/War Damage
N Nature: Scenics, Trees, etc. (always by location - see maps and section III)
O Orders of Entomology and Flora, also Bacteria and other Microorganisms
P People in a multitude of situations (sometimes by location)
R Religion
S Sports
T Technology: Flight, Computers, Environment, Power, Ships, etc. (air/nautical transportation)
U Universe: Space, Rockets, Astrophysics, the Planets (by location), etc.
V Vehicles: Cars, Trains, Trucks, Buses, etc. (terrestrial transportation)
W Words & Graphics: Titles, Charts, Backgrounds
X Experimental

The second letter is called the "Subset Homing Letter". This letter allows us to home in on a specific aspect of the major categories. In the C and N categories this homing letter is location specific (see section III).

The third letter is called the "Subject Specifier" which concisely delineates a particular subject matter of a given category. Always in the C and N categories, and sometimes in the F and P categories, this third letter is location specific (see category listings).

The use of these three letters gives us the possibility of 17,576 combinations. More than enough to create simple and fluid connectivity of mind to reality. (See the Fluid Logic category listings).


In the C and N series only, the second letter (Subset Homing Letter) is dictated by geographical location. The beginning letters of the alphabet - A through K are used for all locations outside the United States. The remaining letters L through Z are reserved for locations within the United States. (ed. note: One can change any of these letters, into any of the alphanumeric combinations,- into one's own personal interpretation - of the ways of constructing the Universe - into its constituent components of understanding,- and thus (and possibly ultimately) into a coherent communication of knowing that very well may be the essence of Knowledge).

Sometimes in the F and P category series, the third letter (Subject Specifier) will also use this sequence for location, though in these situations the letters C (for Canada), and L thru Z (for the United States) are all condensed into the letter N for North America. The definitions for these letters are as follows:

A Asia: Broken into the major countries and regions of this continent
B Latin America: Broken into the major countries and regions of South and Central America
C Canada: Broken into select provinces and territories of this country and region
D Oceana: Broken into countries, continents, and island groups of the South Pacific
E Europe: Broken into the countries and regions of this continent
F Africa: Broken into the countries of this continent
G North Asia, Eastern Europe, and Russia: Broken into the major countries
H China
I West Indies: Broken into the major countries and island groups of the Caribbean Sea
J Far Eastern Europe
K California
L Lake States
M Midwest States
N Northwest States including Alaska
O Atlantic Ocean States
P Pacific Ocean
S Southwest States
T Texas

The second letter in the maps and the corresponding category listings, are derived from this sequence. Note the close relationship in both the second and third letters between the C and N series.

The images that are filed according to their location are selected by the boundaries that exist(ed) at the time the image is taken. The Fluid Logic definition starts with post WWII boundaries and varies according to the boundary changes that tend to occur with the dynamic political realities that are in constant flux.

Fluid Logic necessarily recognizes the sovereignty of all occupied nations as it is apparent that language and cultural bonds are much stronger, truer, and long-lasting than any de jure political boundary.


1. Take film to a lab for developing. When boxes of slides return from lab, keep all slides in the same boxes they are packaged in.

2. On a light table, go through each box separately and edit out slides to be thrown out and throw them out.*

3. Return the remainder of the good slides to their box and determine the date and place each slide was taken according to slide numbers. Waterite this information on the outside of box. (See Diagram A).*

4. Again, taking each box separately, stamp dates onto each slide. Then, orient each slide into the correct horizontal or vertical viewing positions onto one stack, and stamp the place (using the appropriate Place Stamps) where each slide was taken according to instructions on outside of box. Date stamps are oriented the same whether the image is horizontal or vertical, place stamps are oriented according to whether image is horizontal or vertical. (See diagram B). After stamping the date and place on each slide, return all slides back into box in slide numerical order.

5. Now put all boxes in chronological order.

6. Starting with the earliest date, begin to carefully cull through the boxes and put each slide into stacks of corresponding categories as determined by photographer. (All slides should be in chronological order, and separated into their categorical matrix ready for code stamping).*

7. Taking one category at a time, locate the categories last volume and find the first available slot in the volume (the "END" tag). Stamp your new slides to be filed accordingly with the next sequence of file numbers, and correctly oriented to the horizontal or vertical format. (See diagram C and section V - a).

8. Put slides in archival sheets starting from left to right. Make sure each page is coded according to diagrams D & E.

9. Now put the pages into a one-inch three ring binder. There are 15 pages to a binder, each binder is called a volume. At this time the slides are ready to be cross referenced if so desired. (See diagram F).

* (Steps 2, 3 and 6 must be done by the photographer or a knowledgeable assistant, all other steps can be done by an assistant).


a) You may want to have a customized stamp produced that consists of these elements in a single line- Three bands of the Alphabet - a space - a permanent V - two numeric bands 0 thru 9 - a space - a permanent P - two numeric bands 0 thru 9 - a space - a permanent # symbol - and two more numeric bands 0 thru 9.

Here is an example of a code that a single slide might be stamped with: CEI V1 P5 #17. If we dissect the constituent elements of this code it will read as follows: Cities-Europe-Italy--Volume 1--Page 5--(slot) Number 17. This slide now has it's own unique locating and identifying code.

b) Label outside of volumes clearly according to the three letter category code and volume number.

c) Each full one inch binder (a complete Volume) contains 15 pages of 19 slides per page (top right hand slot is left open for an identifying page tag). Slides are numbered left to right. (See diagram D). Each volume contains a total count of 285-35mm slides.

d) The upper right hand slot of the slide page has no slide in it so that each page can be clearly labeled on a card tag that will slip into that slot with the three letter category code, volume, and page number. (See diagram D and E).

e) A card tag that has "END" Wateritten on it, along with the appropriate three letter code category (called the "END" tag) will slip into the first empty slot after the last slide in the entire category, or onto the first slot of the new page if the last slide occupies slot #19. (See diagram E).

f) Keep in mind that the use of ordinary non-archival labeling stickers on the slides and/or slide mounts will deteriorate the image over time because of the chemicals used in the binding agents.

g) It is recommended that the slide storage pages purchased do not contain polyvinyl chlorides (PVC's) as they may deteriorate the image over time.

h) In order to obtain maximum efficiency it is recommended that all procedures be strictly adhered to, and that the system be maintained consistently and frequently.
