I'd set a custom white balance using a gray or white card (or even a white coffee filter if you don't have anything else handy), and turn DRO off.
I have never played with the white balance other than what is available in the camera.
I purchased an expodisc but have never used it.
Can you advise the proper procedure to set a custom white balance?
Lots of good feedback here and I really appreciate it from all of you.
