Hi! I've been trying to do Custom White balance with External flash but keep getting a "Failed" info from the camera.

This is how I did it...I set my camera to M mode, settings of -2EV and aperture of f/4-f/1.8. pointed the flash at 0 and 90 degrees. Used a white balance cap. Pointed the camera on a lit room, white wall and white ceiling. Then when I fired the camera and the flash, the camera gave me info that CWB failed...

Any tips on how to do custom white balance with external flash? thanks!

It may be that the sample shot was under-exposed or over-exposed. Try increasing or decreasing the exposure until you get a successful measurement.
