A Portrait I took nearly 40 years ago!

I am still working my way through my vast collection of transparencies from my very early days of photography in the 70's.
This one was taken on Kodachrome 25.That is an ISO 25 film for those that do not know! Very slow but held such fine detail (see the pipe smoke).
I was very fortunate that I worked in Graphics.Dealing with likes of Kodak, Ilford, Agfa and later Fuji. The availabilty of 35mm film was always there so it made sense to have pre payed slide film every time! lol.
This shot was taken on a Fujica ST 801 and a standard 50mm f1.8 lens.
It was a very advanced film camera at it's time and served me for many years.

By the way.The spec. shows this having been taken on my D800 but of course that's because I used my slide copier on it! lol Oh! confusion?
