Setting custom WB from grey card
I am wondering why I can only get it to set the WB off a grey card sometimes. When I was outside yesterday each time I tried to set the WB off the card I would always get a 'No good' message but I haven't had problems before (but that was indoors). Does the PRE setting not work all that well outside or was it too bright?

Well the camera was set in manual mode. I don't recall the shutter speed exactly but it was around 100 and I did a 5.6 and 8 for fstop. For setting the WB using the PRE setting I didn't think you needed a particular speed or fstop though.

The camera still needs to "see" the grey-card as grey. If you set a shutter speed / aperture combination that would overexpose the grey-card, the camera will "see" it as burnt out white.
