I did.Yes, you can say that Kodachrome 25 in 4x5 under ideal lighting, processed by skilled technicians and printed by hand on Cibachrome produced a wider color gamut. But how many people, in real life, got to use and see that level of film technology?
The only issues I had with digital color space, which no longer apply, was the difficulty dealing with gradients in 8 bit and the level of noise in shadow. Also the relatively low image resolution that cameras were offering until a few years ago didn't appeal to me. Those limitations have long since gone bye bye. Getting predictable color output back to a print was also tricky until good color management software became available.
Photoshop has certainly come a long way since I first stated using it in my work 20+ years ago. We have much better tools today.
Now I'm thoroughly sold on digital photography.
Which, is probably a topic for another forum.
