First time using this new film I bought called Ektachrome EHP P1600X. The results are amazing for film kept frozen since 1999! The native ISO of the film is 400 ISO and it's supposed optimized for push processing up to 3200 ISO. Because it's expired the native ISO is about 200. I used auto-levels and very little other color correction. The grain is nice and large but the sharpness is surprising! I shot the roll from the Canon A-1 at 800 ISO and extended the developing time by 60 seconds (2 stops) and the negatives were perfect.
