I was impressed by number 1, the dissolve as a way to move between 
slides.  Yes, it's a special effect, but it was appealing, smooth, 
and non-disruptive.  I overheard someone in the group saying 
afterward that they thought the dissolve was the ONLY way to see a 
projection, being immensely more pleasing than the BRIGHT, BLANK, 
BRIGHT, BLANK sequence of regular 116/716 slide changers.

Number 2, dissolve just for special effects, I can't comment on, 
because I don't know that one has a choice with the Brackett.  It 
seems to be dissolve only.  I suppose one could flip the dissolve 
lever very quickly and have the illusion of an instantenous change, 
but one is not likely to be able to simulate a 116/716 changer with 
the Brackett--and that is not a defect in the Brackett in my opinion.

The sharpness of the lenses and the brightness of the image seemed 
entirely adequate with the Brackett, and we both know how 
problematic the question of relative brightness of 116/716 has 
become, given our recent experiments.   

The Brackett seemed to me to be much quiter than my 116, but I was 
NOT standing behind the Brackett trying to hear audience comments.  
Our projectionist last night seemed to be having trouble hearing our 
comments, but then MOST of the folks in our group seem to have a hard 
time hearing anyway. :)

Excellent point!  I'm not about to say the performance of the Brackett 
is six better than the 116.  But it is VERY nice.  Notice that in my 
report I wasn't asking for someone to sell me a Brackett, I was 
offering my 116 in exchange!  (The chance of that is either slim or 
fat, depending on your point of view. :) :) )
