Title: AWB or just presets on a Hassy back?
Post by: John_Black on October 21, 2007, 02:11:05 pm
After reading brochures & tech specs I still can't figure out if there is a AWB function on the backs?  The backs I would consider are - CFH-132 (22 MP) and the H3D-22.  I know there are presets and the option to set a specific K value, I'm just trying to figure out if there is a AWB option.  Thank you.

Currently there is not an auto white balance function. You are correct that you can set the Kelvin temperature. You can also perform a custom grey balance by shooting a neutral grey chip in front of the lens and setting that as the white balance setting.

Using an ExpoDisc in front of the lens also works nicely as an alternative to the reflected neutral gray reference. They are now available in 95mm size for the larger lenses.
