I picked one up last week, and used it this last weekend at a wedding, my first impression isnt a good one, there was a lot of different light sources that probably led to my impression, i will try again this weekend but is there any one out there with and tip they can give that helps them use theirs better,
most of my shots were really cold,

you answered your own post.

'differant light sources'.

To accurately do a white balance, you have to pick the light source you are shooting.

If you're shooting RAW, this will be fairly easy with one camera since you can change the white balance in post.

If you 're shooting JPEG you will have to constantly rebalance per lighting enviroment with one camera. Unless, for instance, you like the look of what a tungsten balance does with a daylight enviroment. Artists discretion.

Two cameras, both balanced to differant lighting enviroments will make it even easier.

I use it all the time and 90% of the time is the best wb tool there is. Sometimes though, a grey card works better. In mixed light, I try to wb toward the dominant one. If the lights are all the same, WB 45 degrees between them. The facets on the face of the ED will pick up light from multiple directions. Sometimes I get better wb pointing toward the subject and reading reflected light. You'll just have to use it awhile till you feel comfortable with it.

How do you actually use the Expodisc?

I would imagine, you pop it on and take a picture. Then, do you set something in the camera, or use it later on in post-processing?

I am new to this, but I am always having problems with wb.

With the D200, set lens to manual focus, set wb to preset and hold button till it starts to blink, place the ED over the lens, point at the light source (usually), adjust aperture/speed, shoot. If the message comes back "good", you've got it. If not, it's usually the f or s that needs to be adjusted - do that and repeat.

Thank you for the info. I am waiting to get my new lens and then I will get one. I really want the Nikon AF Micro-Nikkor 60mm f2.8D. I see such wonderful pictures on here with it, I have to get one.
