My AF-101 needs already to be serviced

Gary Senda said:
I have performed a quick dirty test outdoor today. Now I have more data and I can conclude that it is a color balance issue. It is clearly visible and it is increased by the monitor green casting, but it is also in footage. Here is the dirty test

http://vimeo.com/18463467 (pwd dvxuser)

It does not seem a sensor issue and ATW has no casting. In daylight only custom WB is affected.

I think to stop to perform tests now, I don't want the counter go on: it was 1 hour when I noticed the issue and now it is 4 hours (!)

Gary - just curious, what are you using as reference when doing the custom white balance in that test clip?
I was surprised at the difference between your 'Custom WB' and 'Custom WB with Gray Card"

I assume the 'Custom WB' clip was done with a white card - just wanted to make sure.
And if it was - was it clipping when you did the white balance maybe?
Just a thought.

Custom WB's were performed using the white/green card I normally use with my other cameras. One side of the card is white, the other is green. It is a cheap card, but with other cameras it works fine. I've tried to balance clipping the white, correctly exposed and underexposed and the results son't change. I've also performed the WB with other scene files, in video cam mode and interlaced. I've also initialited the scene file and user file at the factory settings. I have no idea what I can do else.
Consider than I'm a sort of maniac with all my tools: the camera was always in its new bag and it was never exposed to high or low temperature, direct sun or any sort of radiation or injury. Two days ago, after performing the white balance, I've seen the monitor turn green-yellowish and from that moment I was not able to reset the color any more.
 
Hi, we received our AF 101 and after performing the same steps .... the same result. Yellow tint, especially skin tones look really bad. Did anyone already solve this mistery? And be aware, don' t perform the black balance... Only if you don't need your camera in a proper way. We own Jvc 500, 5000 Sony ex 1, 270 , Panasonic 100, 200 , Canon 5d. Markus from Germany
 
Means: Be sure you don't need your camera the next 24 hours or days. Try to perform black balance only if you have enough time. For us it is clear, that we can't use it for our next job which is in 2 days. In that current condition we can' t use it.
 
ok i ll join your club now, same thing here, before i got my barry green book, i tried to play with my settings, when noticed that awb button, now everything is very green....... and i cant find how to undo it, not its this way all the time

Are you on the 3200 preset under fluorescent lighting?

The AWB button has a couple of functions which depend on what your White BAL switch on the side is set to and how long you hold it in. DO you know which function youre on?

Why on earth would you say this? It takes less than 5 seconds to Black Balance the camera. And you should Black Balance the Camera each and every time you turn it on.

Best,

If we "must" perform a black balance each time the camera is turned on, why doesn't the camera do it as part of it's boot sequence? Now we have to remember to do it? I've rarely had to black balance (if ever) other cameras I've owned and operated. What a hassle.
 
Because it can happen that you will mix up your af 101 in an until now irreversible way. That' s why. Explantation: got the camera.. Used it...Great Pictures everything Fine...made Black Balance and White Balance... Yellow tinted Picture Parts...exactly the way we already heard in this forum. Advice from my side: until there is no solution i would not perform those steps. Because i wish this not to anyone else. Especially if a production is near and perhaps you have no second unit. If you have a solution, please let me know.

Nobody said you "must". She said you should. It's entirely optional to you to do it whenever you want. I do it whenever white balancing. It's hardly a hassle -- instead of pressing and releasing the white balance button, you press and hold it for a couple of seconds. Is that extra two seconds really "a hassle"?

Every time I use the HVX I black balance - It's part of my boot up sequence as a professional operator…

Well all I know is that the camera does not perform a Black Balance during boot up and that the best performance of the camera is experienced when you do a black balance. Now I don't know of other manufacturers but this is a pretty common practice in the Panasonic line-up, always has been.

To Black Balance, hold the WB button in for long enough to have the message come up that is is Black Balancing. When in doubt read page 43 in the printed manual.

Best,

Jan

Speaking only for myself, I have no idea what you're talking about. I've black-balanced three different AF100's hundreds of times and it has never had any negative effect on the picture.

Good advice. Mine arrives tomorrow. I'll avoid the balance until there's more info on this issue.

I don't understand what you're saying -- are you saying that the images the camera is recording, are now green? How did you white balance? Did you point the camera at something white when you did it? Or did you just arbitrarily hit the button, which means that now your white balance is set to something random?

Maybe we just have a misunderstanding going on here about what the AWB button is for. Put the white balance switch to "A". Go outside. Point the camera at something white and fill the screen. Press the AWB button. It should say "AWB Ach". When it's done, it should say "AWB Ach OK" and whatever you were pointing at (white building, white paper, whatever) should look white.

If it's something that benefits the quality of the picture, every time the camera is powered on (which could be several times throughout the day), it seems to make sense that it should be part of the camera's boot sequence. No, it's not a hassle to push a button for a few seconds. Yes, it is a hassle to remember to do it every power cycle during a hectic day of shooting.

But, I'm used to working within the limitations of the tools available. Cheers.

No need to be so literal - You black balance off the top of the day when you set your white balance, I'll also do it everytime during the day if I reset the white.
