Hi
Can anybody explain to me the proper way to white balance with the DVX100. What does the PRST, A, B buttons all about? Thankls
 
Pop open your manual or Barry's book or use the search on this forum. Just get a white card or something very white set your exposure and set up your lighting, zoom into the white card (this is where your subject will aproximately be) make sure "a" or "b" is selected and hold the wb button on the front of the dvx until the screen says it is white balanced.

You are telling the camera what white is.

We've been using them a bit at film school.

A and B are two default modes. One is for daylight scenes, i.e. if you're filming during the day. The other mode is tungsten mode. This is if you are either a) filming inside under light bulbs or any other in-house lighting, or b) doing any night scenes.

PRST is if you want to do a manual white balance, i.e. stick a white card up to the camera. The card will tell the camera to correct it's colour settings based upon the colour it's seeing. Of course, a brown card or a dirty white card will give a different exposure. You need a plain white card.

I've been told it's best to just select A or B, depending on where you are shooting and the camera will take care of the colour balancing on it's own. If you're shooting at one particular location and the original look of the colour changes all of a sudden (i.e. becomes too blue or too orangey), you can always manually white balance to fix the colours again. Most of the time you shouldn't have a problem using A or B, providing the lights themselves are correctly colour-balanced with the correct gels, but that's another story... So use A or B, and if in doubt, use PRST.
 
rc444, you have that all backwards.

A and B are custom presets that can be set at any point by placing a white card in front of the camera and pressing the WB button on the front. The PRST mode allows you to press the WB button on the front of the cam to toggle between 5600k and 3200k.

Wow. What film school is this you're attending?
Refer to triplej or William's post.
 
To get nice looks, you can blue, red, yellow, or what ever light color you can find balance your camera....So if you white balanced your camera infront of a purple subject, you will get a greenish look. NOW, if you just want plain footage, white balance y our camera, and you can always do the color correcting in post. Good Luck

In addition, you can also balance through colored gels if you want to get some artistic expression in your look by placing them infront of the camera when executing the WB.

Keep in mind that the color of gel you WB through will be the color that is taken OUT of the video signal, thus making the opposite color on a color-wheel more prominent.
 
When I finally opened the manual and read what it said, it became very clear that I didn't know how to work it at all. I too thought that the A and B were JUST presets.

What I discovered was that each button can be set for what you want. The way that I set up the 3 buttons is B - for balance. I use this when I want to manually do the white balance. A- for automatic. When I'm in a big hurry and I have to get something before it goes away. Then the PRST button allows you to switch between 3200 k and 5600 k. I almost always use the B button and white balance because it's rare that you get into situations where you have a true 5600k light source or for that matter 3200K. I should read the book again, and make absolutely sure that I have it straight. I can tell you that the B - balance works really really well.
