FLUT Ignorance

[Rick Darge]

Excuse my ignorance but when I play with FLUT™, what am I seeing?

I've played with settings and I still can't tell what is going on. What's the new protocol for bringing up a light hungry shot? Adjust ISO first then FLUT™? Or vice versa?

FLUT control is a fine control adjustment of ISO.

[Rick Darge]

What are some situations that make FLUT more useful than the simple ISO adjustment? Also, how is something like (6400iso / -2.5 FLUT) differ from (125 iso / 3.8 FLUT) when they both look very similar in terms of noise pattern. I'm playing with an MX shot right now and have been racking back and forth between high ISO, low FLUT and low ISO, high FLUT and I don't know what I'm seeing yet. Is there a mathematical formula we sould be following when using both of these?

If you set FLUT at +2 and iso 500 vs FLUT 0 at iso 2000, you'll get exactly the same image. FLUT is a precise adjustment that lets you fine tune on top of your base iso. The choice is yours as to which one you want to adjust first.

Does the FLUT adjustment at low ISOs differ from the FLUT adjustment at higher ISOs? Does it compound in power as you move up or down or is it independent of where you set ISO?

[Brook Willard]

FLUT adjustment seems like ASA adjustment minus the clipping. It makes me wonder if, perhaps, shooting at ASA 100 with a FLUT of 3 is better than shooting at ASA 800. Same exposure, but minus the clipping... right?

Test time...

So we're just affecting the midtones then?

It does the same thing regardless of what iso you're at.
If you're at 250 and you set flut to 1.0, you're increasing by one stop
which will look the same as iso set to 500 and flut set to 0.

Nope. It's exactly the same either way.

If it's the same then as ISO adjustment, why call it FLUT and not just ISO-2 ?

ISO in the new color science is based on the core of FLUT. The real magic happens in FLUT and ISO settings are like FLUT presets.
