I must admit that, beyond their photographic virtues, I have a sentimental attachment to three films, Kodachrome, which captured most ot my childhood and was the first slide film I used (or even knew about - I remember when my dad started trying Ektachrome, mostly for the higher speed); Verichrome Pan, which is the first black and white film I learned to develop; and Tri-x, which is the first 35mm black and white film I really learned to use. When I came back to serious photography after a long break a few years back, I was sad to see Verichrome being phased out. But at least it was pretty easy to switch to Plus-x, which I had used before in 35mm. And I have acquired a taste for many others since, including APX100, which I was really developing an interest in when Agfa went under. But I have yet to find a slide film that I like as much as Kodachrome, or that seems to go as well with the old cameras I use a lot of the time.
