One of the potentially very useful features of the D200 is the capability of the built-in flash to serve both as the commander and, unlike the D70, participate as one of the flashes.

So I set up by SB800 off 30 degrees or so to my left, placed a large doll (no human volunteers available)in a chair well spaced out from the wall, and began firing away in manual exposure mode, 1/250 shutter, ISO400 to avoid running out of flash. I tried two configurations:

(1) Built-in running commander only, SB800 in TTL as the only significant light source. Worked ok after I cranked in +1.3 compensation for the SB800.

(2) Built-in and SB800 together in TTL - required +1 compensation on each to arrive at a reasonable combination of exposure (full histogram just short of "blinkies") and shadow fill.

Once I had found acceptable comp values, the lighting held constant over a large aperture range, proving iTTL really was working. I was surprised at how much comp I had to dial in for full exposure, not quite sure what to conclude. I believe my configuration was fairly neutral, avoided the dark object up against the light surface. Anybody else tried this, and what was your experience?
