It's perfectly feasible to do color processing (e.g. C41 color negative and RA4 color prints) at home. You don't need outlandish equipment, very deep knowledge or a lot of money for it, either.
This blogs goes into the practical steps of choosing chemistry, mixing it, using it and storing it, with a focus on accessible and sensible solutions for a home user.
The scope of the blog is C41 and RA4, but the concepts can be extended to ECN2 and E6 processing as well.
