Shot using HD camera vs. copied from film

[bobcarla]

When I look at remastered Blu-ray DVD's I never get image quality near to scenes filmed with digital HD cameras. I just watched one of the Planet Earth disks. It was fabulous when I saw it on the Discovery channel and it was fabulous when played on my Blu-ray player.

Yet I read again and again that movies shot with film and then scanned into an HD format should look every bit as good as those, like Planet Earth, filmed using digital HD camera. Their argument is that film has more than 4 times the resolution of the best HD camera.

I hear all that but my sampling remastered movies into Blu-ray are no where near using HD cameras.

It is true that film is so much higher resolution that sampling should be like filming the original scene digitally.

Can anyone tell me why it's not.
