storing white balance settings at DVinfo.net

As I understand it, the hd100 can store white balance settings. Why would anyone want to do that?

Lets say you are filming in 2 location at the same time, for example inside an apartment and on a balcony or out door. This option is design to save the WB preset time. while your subject is moving from one location to another you only need to press a button.

BTW all pro cameras have that option.

I think what Brian is referring to is the fact that WB values of A and B are also stored in the scene files - which complicates the sharing of scene files that have WB adjustments (R/B) in the CAMERA PROCESS menu.
It also means that loading a scene file will wipe the existing A or B WB values in memory, and replace them with whatever was in there when the scene file was saved.

what I dearly wish for - to be able to dial the WB setting in directly. I could so use that. its great to be able to set 4300 when shooting 3200 for some extra warm tones, something I miss from the F900. I've also noticed that the hd100 has rather course WB settings, 2500,3200,4300,5200,6500,8000 rather than showing increments of 100 like some other cameras. I'd PAY for this firmware upgrade on my 100.... hear that JVC... I'd PAY for that ability.

Steve, I hear ya! Barlow Elton from this board showed me how his XLH1 could do that and I just about crapped my pants. That's a feature the HD100 needs (no need for warm cards).

Doesn't the camera allow you to paint the whole picture using the R and B controls? Seems to me that's a lot more flexible, dial it to the exact color you want rather than going along a set spectrum of color temperatures.

Yes it does - and it is more flexible - but it isn't as straightforward as dialing in 100K increments.

And manual iris isn't as straightforward as leaving it in auto all the time, but you don't see people doing that.

I tell you what - once I saw that feature in action while the H1 was connected to a monitor, I thought it was the coolest thing. It was definitely quicker than manually dialing in color values. Instant magic bullet look after look in a couple of seconds.

Not quite as flexible, but way cool (or warm - pun intended).

3200 on one camera is not 3200 on another but sharing scenefiles ensures everything is exactly matched between cameras. Whenever we shoot multicam we select one scenefile and load it in all cameras without any changes to the scene file.

Try for yourself on a multicamera scenario. Whitebalance the camera's side by side you may get the same value but white/gray may look different between the cameras. Now save a scene file from one camera and load it into the other. Do you see that your white/grays now match?

This is very valuable in post production where you have to deal with matching up histographs. If the cameras are as close as possible to begin with then that saves a ton of time later on.
