Jim:

Thank you for joining this discussion. I appreciate your comments.

The balance between interior and exterior illumination is a constantly moving target. As mentioned earlier, shutter speed and aperture are chosen for depth of field, 22 feet of travel at 15 miles per hour, etc. This leaves interior illumination (SB-R200s) as the variable.

Following some testing prior to leaving the department's parking lot and heading out on the road, I selected +0.7 and left it there, which produced a bit of over-exposure at times. I will be adjusting exposure in final pp, either by Exposure in RAW and/or Levels, Shadows/Highlights in PS5.
