1) What all is involved in the K-14 process? How many, and what kind
of chemicals are there? Why have they never been available to the
public?

Don't know. Kodak has never been forthcoming about what is in the process.


2) What would happen if someone tried to process Kodachrome film using
the E-6 process?

You would end up with orange film with nothing on it.


3) What is the difference in chemistry between Kodachrome and
Ektachrome films?

Don't know.

4) In detail, what do each of the 7 chemicals in the E-6 process
actually do? If you omit the color developer step, will you get B&W
slides? you'll get blank film.

1. developer - develops exposed silver to a normal b&w image
2. stop bath
at one time a second exposure to light was needed here.
3. color developer -- develops the rest of the silver and causes the dyes
coupled to the silver to "develop"
4. bleach - converts all silver to solulable.
5. fixer - standard fixer disolves the silver.
6. wash
7. stabilizer -- makes the dyes last longer used to be formadlehyde.


The process can be cut down to a developer/color developer combination,
bleach/fix (blix) combination, wash/stabilizer combination assuimg the
chemicals are not reused. If they are to be reused a wash or stop bath
would be needed between the developers and blix to prevent
contamination.



5) Is it possible to process C-41 print film using E-6 or K-14
chemicals to end up with slides instead of negatives? What about D-76
B&W print film?

no. but there have been some interesting results published using C-41 for
E-6 film.

6) Since color slides were invented in 1936, what year were the first
color prints available? All of my parents' family photos older than
the mid-60's are all B&W, except for color slides from the 50's.
no idea.
