Epic at 320?

Perhaps a feature would be nice where you can select multiple user grades and flick through them while recording on the monitor - but the histogram always shows the RAW metering no matter what grade you select (so you can ETTR)... Or can you do that already?

Personally I always found that when FLUT was introduced too. I steer clear of it because anytime I use that to brighten my image, even if I'm nowhere near white, the image starts to lose saturation and depth (for lack of a better word) . I have always stuck to ISO and curves. I see the same sort of visual effect here in the correctly exposed image (before I darkened it in post) that turning up the FLUT gives me - very milky bunched up tones that all push towards white but don't clip.

FLUT is just a fine tuning control for ISO, I don't think it's supposed to give you different results than using ISO would.

From the Redcine-X manual:

FLUT™ CONTROL
Once the preferred ISO is set, the FLUT level allows fine-tuning of the ISO level. FLUT control units are in stops, so +1 FLUT Control is the equivalent of brightening the image by one stop or doubling the ISO value.

Yes, FLUT and ISO are identically mathematically as described in manual.

So FLUT is in essence FISO, or Floating Point ISO?

 

[Graeme Nattress]

That's as good a way of putting it as any....

From the Redcine-X manual:

Hi Graeme,

I thought the biggest difference with FLUT and ISO is that FLUT remapped the tones slightly so no clipping occurred. My understanding was that it bunches the shadows/midtones into into the highlight area whilst trying to retain the highlights - whereas ISO is a complete linear shift with no highlight protection. At least that was what I thought, can't remember where I read that.

 

[Graeme Nattress]

karl, ISO and FLUT work identically with the highlight retention. The "exposure" control was left as pure linear gain should it be desired.

Thanks Graeme,

I knew there was some sense in what I was saying but thanks for pointing that out. I had my exposure and ISO controls the wrong way round :-/
