How many lenses resolve at 4k?
How many human eyes resolve at 4k and at what distance? If the viewer has to be in a cinema to see any difference will this really catch on?
At the moment both cinema and TV are producing high quality content at 2k. And yet most are watching in formats that good quality DVD SD would be fine.
Other much more important factors regarding picture quality are ignored as this does not involve selling and requires learning.
Diffuse or focused light, subject and lighting contrast, good exposure, no flare or light scatter, lenses, f stop, focus, DOF ....
A good film crew will producer far better quality on 2k than an amateur with a 4k.
Producer higher quality images at no extra expense - read books.
