Let me know when “digital motion blur”...
A polaroid looks different from film too.
Always will.
And vinyl sounds different from CDs.
The last movie I saw in a theater drove me batty with film grain.
Not sure which blur you’re referring to. Most I know of are being corrected.
There are flaws with every recording medium, visual or otherwise. Just a matter of whether the balance of flaws in one medium are preferable to the balance of flaws in another.
