You gotta start shooting in RAW and get yourself some Capture NX2 software, camera WB is a thing of the past, get with the times geez
Even my D300 is old technology now with the D90 and D700, I haven't even had it for a year yet.
On a side note does your D200 have the sensor for the wireless remote? I just found out mine doesn't have it so the remote is useless to me, I must of spent a good 3 hours trying to get it to work
Anyway you can have it if you want.
