Q: 2. Hi, i have read the instruction manuals, and it says on step 5 to pour stabiliser. However, this package does not include the stabiliser powder. How does it effect the result if we are not including the stabiliser?

A: If you are shooting modern color negative film, a "stabilizer bath" is not necessary. Up until the mid 90's, the final rinse bath in the C-41 process was called a "stabilizer bath," since it contained Formaldehyde or Formalin. Modern color film emulsions include chemical stabilizers within the film emulsion itself.
