C100: C100 White balance too blue

Hey,

I noticed that my white balance on my C100 is always too blue. I noticed it at blue hour, it looked twice as blue as my eye. Is there a fix/tip for this problem?

Thanks!
 
Can I ask a dumb question? Are you sure you're not just judging by the EVF on the cam and finding it too blue? That EVF is notoriously "blue" compared to reality. . .maybe WB is actually fine? As for dialing it in/presets. . .I have found, at least with the EX1, that the camera generally knows what it's doing better than I do, and every time I've tried to dial it in by eye using the picture profiles I've come home and been horrified by the results (that I thought looked good in the field on the cam's viewfinder), whereas if I do a regular manual white balance or use a preset, even if it looks a little cool on the camera's viewfinder, later on a larger screen everything looks good.

Someone on here also mentioned a while ago that when you dial it in your are changing the colors channels differently than when you do a manual white balance. . .I BELIEVE manually, the cam adjusts all three (R, G, B) channels to achieve the white balance at which it arrives, and when you dial it in, you're only changing the red and blue, while green stays the same. Or maybe it's only red and green while blue stays the same. Something like that. So you can get the same numerical readout (e.g. 3500K) from both a manual white balance and dialing it in, with very different results visually. Maybe that has something to do with it?

Could always get some of those warm cards with different variations of white blue and orange to alter your white balance to your liking.

I am judging on the screen of the C100, I dont use the viewfinder. As the viewfinder is unusable, I did not check on my computer though. So maybe the screen is also way too blue. Not sure :/
 
Yeah found some Behind the scenes footage of a video with a c100 with the interneal screen and on top a atomos shogun. And The internal LCD was way more blue. Is there a fix for that? As I do not have a external monitor and I am working with a director next week who wants to see everything and I am sure she will keep telling me it is too cold, I want warm colors..
 
DON'T manually white balance and use the C100 LCD to judge white balance. Use a white card. Sometimes the presets are ok, but not always.

Thought about maybe getting an external monitor?

Clearly you are at that point if you have a director on set needing to see what's going on.
 
I used to white balance when under 100% tungsten, such as interviews and never happy. I have a Small HD AC7 and DP4 I calibrated yet no matter what I do it sucks. Using the attached LCD
for color confidence is real rookie. So, the preset has nicer skin tones. Pros usually don't use the light bulb icon but with my C100 it is more better.

If you are using FCPX as I am about to finally transition to, buy this little chart and then in post you box and click the chart and Shazzam! Beautiful balance and instant correction:
