Derek, you have been doing a great job as a projectionist.  Your system and
philosophy of projection is excellent and fair.  First you adjust the
projector carefully and then you let the slides fall wherever they may.  
You do not attempt to adjust the projector to correct for people's mounting
mistakes.  You only adjust the focus which is reasonable since this is
affected by the thickness of the slides.  My slides always project well
because they are mounted carefully.
 
Now, I realize that Jon Golden and his magic fingers can adjust the
projector on the fly and from slide to slide.  That's certainly a talent
but it is also very machine depended.  If one does not have the appropriate
machine or Golden abilities, then the projector should not be adjusted.
 
The worse adjustment I have seen being practiced, and I am sorry to say
that they were doing it in the Chicago Stereo club, is to try to change the
horizontal separation to match bright areas in the background and eliminate
ghosting.  This ajustment is totally unjustified and destroys the stereo
window which contributes greatly to the projected impact.  I am surprised 
that some people find it appropriate...
 
In the Detroit club only once I had a problem with the projection and that
was during the first competition night this year.  The horizontal
separation was off and the images were projected one foot or so from our
faces.  It was a nightmare and most slides, including mine, were killed
that night.  One of my slides got 19 points which was one of the lowest
scores of the evening.  I send the same slide to the non-star PSA
competition this year and it won first place!  This is a proof for me 
that projector misadjustments can greatly affect the end result.
 
Back to reading Golden's entertainting and educational posting for the 
third time...  (Jon, how many times am I going to tell you not to post 
anything late after partying all night long... ;))
