shooting a mixed wedding....

meaning a light and dark skinned couple...

any special techiniques for that?

No. Expose for the highlights, develop for the shadows. ACR 4.0 fill light could help.

Thanks.... I kept wondering, I have not shot one yet..but alot of people around me are talking about it...so, I thought to ask now..learn and go on.

Will you be shooting RAW Lisa? That safety net has saved me at more than one event. You might want to bracket some of the exposures, although I wouldn't go crazy on a myriad of settings - that will only drive you nuts later in PP. Tim has some great advice which I can't improve upon, so I won't even try. - Stu

I generally don't shoot raw...and I have not had a mixed wedding YET...but in our area..this is becoming very common. So, I must prepare...and be ready for it.

If you're not quite comfortable shooting 100% RAW yet, set the camera to shoot both simultaneously: RAW plus large fine JPG, or whatever that setting is . This way you can let the "camera" do all the processing and see what it comes up with. Likely you'll be please with most of the results if your exposures are pretty on.

For those shots where the ETTL or metering was "tricked" or just thrown off, you have the RAW safety net to play with. That should give you in the neighborhood of 2-stops of saving grace if something really gets hosed. - Stu
