When to limit a .quad

On my printed out limiter target (pt/pd), the pure whites count to 250 with a densitometer (251 with eye measurement). Is limiting suggested?
If limiting is optional under this circumstance, what kind of difference will it make if I choose to limit.
Thanks

I suggest limiting first just so you don’t mess the highlights up during the actual linearization.

Thanks, Walker. So the limit number should be 251-4=247. Is it correct?

Zhe

Yes.

all the best,
Walker
