Kodachrome had the best darned resistance to color cast of any transparency film ever fade.
You could shoot in situations that would send any competing slide film into conniptions...open shade, intensely cyan-casted fall sunlight, you name it, ol' Kodachrome could handle it well while everything else turned harsh, ugly, and every color of the rainbow except what you wanted. And there was just something lovable about it's straight-up, ingenuous, in-your-face take on color. And talk about Max-D! And I used to work almost next door to the Kodak Las Palmas processing plant, 4 hour Kodachrome processing, two runs a day.
And on those rare occasions when it faded, it somehow managed to do so with exceptional grace yielding a warm and fuzzy look that was often an improvement on the original. If your family memories must fade, let them fade on Kodachrome.
Next eulogizer, please...
