Hi gtphil1,
I'm just adding in a precision option in the settings - so you can set to arbitrary fixed-point decimal places,

Hi gtphil1,
sorry for my slowness - a few things meant that i had trouble pushing updates.
I've pushed some updates to a 'testing' version on the website: LUTCalc 3.3 Beta 1
this includes 'Decimal LUT Precision' under settings - the default is 8 decimal places, but you can go as far as 128 if you are so inclined ;-)
I'll spend some time checking I haven't done anything stupid with other additions and then should have it updated soon in the main online version and Mac app.
Thanks,
Ben
Hi, I'm running into precision limits when converting HLG to linear (Display HLG OOTF (Normalised)). Example file attached. It looks like values are limited to 6 decimal places in cube output. This LUT outputs really tiny values, so it ends up with banding and a lot of values rounded to zero. Would it be possible to use floating point exponential notation instead?
For context, I'm trying to work with HLG footage from the Fuji X-T3 in FCPX, and want to convert to linear space for color edits and other effects. I've tried applying this LUT and its reverse as a "no-op", and a lot of color definition is lost.
Thanks!
