Went and saw the exhibition at ICP earlier this year. Nice to see the color photos (lots of them, mostly from post-war magazine shoots), but what I found even more interesting was the correspondence from Capa, his brother Cornell, and others regarding how to deal with the various color issues that arose with early chrome emulsions; lots of discussion of color casts and recommendations for using filters (UV, primarily, IIRC). There was also a detailed display showing the differences in how Kodachrome and Ektachrome had aged (Kodachrome looked far better), and what had to be done to restore the images.
