Hi Wei-Hao!

Thank you!
You are absolutely correct. I am is the same opinion.

I 'd like to add sg: If you look the slides at low light conditions, the 
effect will be similar. The image getting much more softer and the details 
are getting disappear even in the shadows. The brightness and contrast of 
the image are decreasing. Monitors has very little brightness and dinamical 
range compare to the normal looking of the slides.

BTW, have you ever tried to project your 120 format transparencies? I have 
never tried it because i don't have 6x7 projector. It might be an other 
dimension!
