Back in the day I used Kodachrome almost exclusively. I tried others, but always came back to it. The colour rendition*, detail, and low grain were delightful, although K64 could be a bit red on (Caucasian) skin tones. I found K25 almost flawless, but with the restrictions that low speed imposed I might as well have switched to medium format.
There was much chatter about which labs were the best. I used to send mine to Switzerland.
This thread is making me want to buy a projector and dig out my albums of slides, which I haven’t looked at properly in decades.
* makes you think all the world’s a sunny day, oh yeah
Good luck, in having a look at your old slides. I must do likewise soon. It will be lovely to see again photos of my sons growing up, house moves, holidays, and so on.
I have sometimes thought that the audio equivalent to a roll of Kodachrome 64 would be an LP12, Ittok, Rega R100 with an A&R A60, some QED 79 strand, and a pair of Heybrook HB2s.
When I first started Photography, I thought that Kodachrome 25 (or was it Kodachrome II - ?), was the only colour film you could get…!! How on earth I got any results at all, using an Ilford Sportsman, which had no metering and ‘guess’ focusing, I still do not know…
A bit later, I bravely tried K64…!! Later still, I saw my first SLR - a Practika MTL3 - and the rest you can guess…
