The light in your 2nd image looks like came from the "leakage" of your flash
directly and some reflection off the wall, may be only a very small amount
is came from the ceiling. But for indoor I highly recommend to use flash
bounce off any where possible, the additional light could be very useful. I
did some with high ceiling too (not as high as your example) with Fujipress
800 ten years ago with the 100/2, 24/2 and 180/2.8, even with F2 wide open
it wouldn't work without flash.
