There's no doubt about it, V50D is an amazing film as we can all see from Jose's experience and superior lens etc. However, we are still discussing Ektachrome aren't we, or is it already forgotten ? It seems that this subject of the discontinuance of Ektachrome touches on the wider question of how long we will have E6 colour. Colour reversal film in all its forms has been with us for three quarters of a century. Surely we can't write it all off just because Kodak has finally come up with a great negative film,( and very convenient for them to slit down to super-8 etc.)
Negative does of course rule in cinema analog filming, but for years small independent folks have been making films on colour reversal that probably would never ever have been made on neg. Two reasons I can think of:
1. So much cheaper to see the result. A scan or print is not compulsory, at least at first. Either of these potentially risks damage to the film.
2. Dust and dirt come out black, not white which is generally far more obtrusive. I saw some specks on your film Jose
Regarding the cost question though, I meet people almost every day who are trying to get involved in film, but who I think will be put off by neg. They want to see and touch the film as it comes back from the lab. Study those tiny images on the lightbox etc.
Ditching reversal is a bit like telling artists they have to paint in water-colour from now on, no oils allowed.
