Fast advice - DMR manual WB

[Overgaard]

Advertisement (gone after registration)

This might be somewhere, but I'll be going in the field with the DMR and haven't been able to find this one:

 

In pointing to something white to get a manual WB setting, I sometimes get the message that the exposure was too bad - and that no WB was set.

 

I wonder if there is some "rule" as to when it is too bad (to little light or something else) so that I know when I'll be able to do manual WB and when not.

 

I prefer to do manual WB even in daylight, and as often as required due to change in shadows and light, so as to get the light and WB right in the shot and not "fixing" it in the computer. (I hope it's me, because mostly when I really need a WB, it's indoor in low light.)

 

 

Hope someone can help.

It normally means the exposure is off. I can't remember exactly, but I thinks it means you are over exposed too much to get a proper WB.

Thanks. I read the manual again and it states that one has to point (the middle spot in the focus screen) on something neutral gray or white and then press the shutter. AND that the exposure has to be correct.

 

For some reason it hasn't been (which is weird, but nevertheless:) I just tested it now and it works very well and precise. I would love to be able to read the K-number somewhere, but that's not possible.

 

(I think it was you who at some point stated that you had tried to use a Kelvin meter but that the DMR did a better - or at least good enough - job without?)

 

Also, a neat little details is that if one want to change the white balance again, one just press the "set" button in the center of the (left corner) wheel and shoots towards the new neutral grey or white surface. And it's set.

 

See, that's quite easy and nice. And fast! And actually an easier way to do it than using a Kelvin-meter and changing the Kelvin-number.

 

Anyway, I'm off to Africa in few hours and look forward to give the DMR some field experience (education, human rights, food crisis, agriculture, atmosphere and perhaps an elephant for my daughter).

 

Only little bug left is a bit of back-focusing that I'm trying to handle. Had the DMR off, the focusing screen out. Will try some other screens tomorrow before I leave.
