Happy Medium and "newbies"
About Kodachrome - even though it is a K-14 process and it has to be sent away for developing - my slides of 40 years ago are still sharp and highly detailed with distinct color separation.
Best of all, they exhibit no fading of the color dyes whatsovever - something which cannot be said of the Agfa and Fuji slide film that I used during the same period or tried again many years later.
But don't take
only my word for this assessment - read below and check out the other comments at the reference given below. Do your "homework" and choose wisely with an eye towards the future use or appreciation of your slides.
"Its longevity is un-matched. I've picked up boxes of my grandfather's WWII-era Kodachromes and they looked as good as new. I dug through and found some Ektachromes or other E-4 process films also. What image there was left was hard to discern." comment by Kodachrome Loyalist
"It is almost haunting at times to look at Kodachrome slides taken so long ago, they still look like the day they were taken." comment by jbeecham

Please don't take my comments as an adversion to explore the range of photographic possibilities, but one should keep one's eye toward the future enjoyment of your past photographic efforts.
Again, my best wishes in your photographic endeavors.
