Custom WB

[tonyq]

Hi all,

I am thinking of making a custom WB (white card), for use with my G6 in the home, using the house lights and flash, subjects about 4-5 feet away. I believe that you have to fill the screen with the white card before you take the picture. My question is, is it O.K to take the picture close up, or do I have to stand back and zoom in to fill the screen so as to get the affects of the lighting.



P.S. I hope this makes sense to you.

I keep a small (5x7?) piece of white matboard in my bag, but I've never even used it. I usually just set the custom WB on something white (a wall, a t-shirt, a sheet of notebook paper) that's lit in a similar way as the subject and i've been really impressed with how well the wb works. grey works, too, if it's a neutral gray, it's not using that area to set the whitepoint, it's just using it to strip out the color cast, so it's pretty forgiving. I don't always fill the frame and it seems to work OK, seems like as long as the majority of the center of the frame is filled with the white or gray subject, you're good to go. Zooming in would be better than moving too close to a small object, because reflections and your shadow could throw it off.

My old camera didn't have this feature, so when I switched to the G6, this was one of the things that just blew me away about it, even though most cameras have it now.

The important thing is that the card be in the light that will be falling on the subject. Obviously if you move in close, you don't want to make shadows or otherwise change the light source.
