I don't understand this rotation _and_ vertical adjustment.  The minute
you rotate each chip individually to correct the phychological tilt
thatbothers you, you have introduced vertical misalignment which
_cannot_ be corrected not matter what vertical adjustments you make.

True...but extremeties of misalignment can be minimized by
MASKING......and it deopends on the image subject depoth
ratios...etc...I am not going to get technical and academic about it but
I usually mask down tilted shots a bit....so that I have the horizontal
play I need to get things aligned properly....bu I know it works for
me...and DR.T ...you were here...you saw the PROJECTED show I put
on....many of those images were tilted deliberately......I guess it
worked....but I wont comment here...I'll let the crowd decide for
themselves...not me?

In viewers...thats another story...and most of the issues with tilting
the camera are a fractionth as critical as in projection.
