P3D re: Which side is the front

["Ivester, Paul" <ivestep@xxxxxxxxxxx>]

In the past when using heat seal mounts, I always 
mounted with the front of the slide toward the 
larger opening.  This allowed me to position the 
chips against the smaller opening and adjust the 
alignment before closing.  This method ran into 
trouble when the adhesive was changed from a very 
dark green to light blue.  In a viewer I then had  
an ugly border of translucent adhesive around the 
slide.  What I started doing to preserve this 
method of mounting was to color the border of the 
mount with a black permanent marker.  This looked 
better, but was time consuming.  The next alternative 
was to mount upside-down.  Left and right are reversed, 
but the image is not pseudo, and infinity separation 
is still valid.  The finished slide is then viewed 
from the side with the smaller openings, and you don't 
see the annoying border.

When using Spicer mounts, I use the RBT transfer 
technique, previewing the slide right side up in the 
RBT, and transferring it to the small-opening side of 
the Spicer mount.
