White balance with PC TruColor v3 is green

[George Strother]

I have been testing with the PC TruColor v3 setup file and find that white balance taken with a DSC white card or a Vortex Warm 1 or Warm 2 has a green shift.

Is this normal for the PC TruColor v3 setup? Does it need to use presets only, or do I have a camera problem?

White balance is not affected by the configuration file. It's another issue. Try using different configuration while keeping the same lighting and chart and you'll see. Be aware of the fact that if you store a config file that operation will also store the white balance at that moment. If you then white balance and then switch to the config file your whote balance will be reset to what it was when you save the configuration. In order to correctly test a scene file you need to load the file first and then set the white balance.

Hi Paolo. Thanks for the note.

White and warm balance were performed after the file was loaded. This hasn't happened on other scene files, just TC3.

I like the overall look of TC3. I was only wondering if this green shift affected other HD100s, or just mine.

I used it the other day on my 101E and the footage was green as well, didn't cause any problems in post though, there was loads and loads of detail to play with,white balance was also carried out after loading the file.

Thanks Ian, that's what I wanted to know. Maybe I should have mentioned that fixing it in post is cake. On set, it does freak the client out though.

Just for the record: there is no green cast with TrueColor, not the way I made it. It would be silly to make a scene file that looks green just to fix it in post. Please double check your settings and verify the calibration of the camera using a vectorscope and appropriate chart. There can be variations to the camera that can cause the color matrix to react slightly differently, although this is the first time I hear about it. The whole point of TrueColor is to give the most neutral image acheivable with the HD100. TrueColor is not a "look" configuration but a way of preserving your data signal so that post work can be done with the maximum amount of information available.
The configuration has been tested on the field by myself on commerciale shots and endless interviews in a 3-camera setup and it never showed a green cast. Many people from this forum also used it and never reported anything like this. Keep in mind that TrueColor or any other scene made for the HD100 will not work with the HD200/250 series.

I double checked everything on the day of the shoot as I wasn't happy with the look but as it was a small shoot for myself it wasn't an issue, I tried other scene files and all seems fine with them, all as I would expect but the day of the shoot was quite horrible weather so it wasn't a day to be playing around really, I didn't mean to say it was normal the green cast just that it had happened to me also, since then I have been working alongside a PDX10 so have been running a scene file that matches in with that and have been a tad busy to go deeper into why this happened and as I have a 17" Panny monitor due to turn up any day I wasn't going to play till I could truly have a look at the output on that, the camera has been at JVC in the last year for updates, checked and passed with them and all other scene files look fine and the same as before the updates, I didn't have true color on the camera before then to say it is any different I'm afraid.


To be honest I thought that it must be a setting that was wrong but I couldn't find anything, now someone else has said the same thing I'll dive back in and triple check.

Thanks for the response Paolo, I'll see what I can discover.

Never had a green cast with TC3 either. Sounds like a camera quirk.

[George Strother]

Probably a quirk in my camera, maybe Ian's.

Presets are fine, I never use FAW, but I checked it and it's fine too. WB taken from a DSC white card or Vortex Warm 1 or 2 goes green.

Change or just reset the file, re-white, everything is normal again.

I've used nothing BUT TC3 since I got my HD110 and I love it. I've never seen a green shade to it.

You really should try some other scene files just to see what the camera is capable of.

keep shooting.

Same here.

Paolo, Is truecolorv3 trademarked? and to give you credit for using it do you have a logo?
PS Thanks for all the hard work in creating truecolorv3.

Hey Joe, good questions :). TrueColor is copyright Paolo Ciccone 2006-2007, it's not trademarked. If you want to give me credit it would be nice to add something like:

Camera Color Calibration: TrueColor (c) Paolo Ciccone

Thanks!

[Saul Martinez]

How can I get the Paolo's Trucolor V3?
Thanks.
