Scripting CO v 7.1
Hi all
Despite my effort to put together Pentax and Phase, I still cannot use PEF files from my Pentax 645D with CO… : (
So I have to export DNGs from the PEF (in camera DNG's aren't color accurate) and open the DNGs in CO.
Does anyone here knows if a script does exist to increase WB to 400° Kelvin, for a serie of pics as I find the DNGs to be way too cool temp…
Thanks !

I absolutely understand what you're asking for regarding the script, and someone very well may be able to whip that up (but not me) however I think the most simple solution here is to add a grey card/white balance target shot into your shooting workflow so you can do a simple white balance adjustment on the first frame, and then quickly copy/paste the adjustment to the rest of the shots in your series.
In fact, as someone who spends most of my time as a digital capture tech, I recommend always doing this for every shoot all the time always, whether or not someone comes up with a script based adjustment like the one you are hoping for. Then it won't matter what kind of crazy file conversions you need to run through - you'll always have a good reference point.
Good luck!0 -
Hi Brian
Thanks for your input.
I agree with you and do use quite oftenly a grey card, however, when shooting a boat from helicopter a grey card is not that handy...0 -
So you want to be able to run a script that adds 400 to the white balance? So you have some at 5000 some at 5500 and you need them to be 5400 and 5900?
Its not that easy as the cos file represents white balance with (i think) r,g,b values that CO then interprets.0 -

Hello Rap
yes, exactly! you nailed it…
Just in case you try, (I know you're a great scripting guy 😉 remember I run the French version of CO
I had a similar problem and added the required amount of kelvin 'warming' to the camera's WB. Instead of 5500k I set it to 5750k.

Hmmmm good idea Nick
I'll have to see if I can do this with the Pentax… However this is a good solution for the future, now what's about the few last thousands shots waiting to be processed…0 -
For that I will pass you onto rap_digital again!
Seriously though, you must understand that using DNG in CaptureOne is not going to be the same as using a supported RAW file. When you open a DNG in C1 you will notice that the "profile" for DNG files is "DNG File neutral". So, a lot of the power of C1 (the excellent camera profiles and raw file rendering) is lost as the file is simply displayed "as is" / as converted from the PEF>DNG process. It sounds like you are doing more work than you should be doing and using the wrong tools. My suggestion to you (if you have not already) is to try a PEF RAW converter like Lightroom (or other) that has a camera profile designed to get the best from your camera's RAW files. C1 is not it ☹️
Best of luck to you!

This is exactly what I'm doing, this saves a lot of time, although after having done loads of comparisons C0 is still better for rendering! For small shoots, I convert PEF to DNGs (in camera DNGs from Pentax have lesser color quality/fidelity than Adobe converter), and yes, CA and lens corrections aren't available but I deal with this in PS on the 16bits files… BTW C0 7 is much faster than LR4.3
However on both PEF/LR and DNG/C0 wb is too cool by 400°K and 3°tint… I mainly shoot yachts in blue universe (sky and see) and awb is obviously fooled by that blue cast…0
