Image Finetuning Limits

[AnotherDave]

I was wondering if it would be possible to implement a limiter for the digital ISO in Image Finetuning.

When you are using finetuning to display the corrected ISO for an ETTR style of video shooting, it would be a great help to have the EV adjustment programmed to shut off once a user-determined camera ISO setting was reached.

Setting the EV to go back to 0 if you went past 6400iso in camera and back on if you go below.

Is that possible?

IMHO, and I don't do video much so happy to be corrected, digital reduction of ISO should only be performed when needing an ISO below 100, or for very fine tuning of exposure (better then 1/3rd stop).

In both these cases, I don't see why there would be a need for some sort of auto setting.  Both use cases are pretty specific.
