I haven’t used this for some time. Here is some feedback. I tested it on à contre-jour, late afternoon at the Waterfront, Cape Town.
1 I find that it isn’t a set it and forget it auto. When I adjust other modules, I have to set this again.
2 Sometimes, I get a student value of 1000. Workaround is to switch back to camera and then back to itcwb.
3 AWB bias is finicky. As I go up or down using -/+, the values from the colour dropper could go back and forth until a sufficiently high or low value.
PS I haven’t verified whether items 1 and 3 are specific to itcwb or other modes as well.
