Yippie! A spinning darkroom door!

"I just finished my "baffle entry" with 3 90 degree turns."

Even with the sun shinning directly into such an entry one
is likely safe. That I wouldn't think be the case as common
sense would require a blocking of direct sun light.

The university I attended Physics Department's photo lab had
1 90 degree turn; through the entry, take a right, and three
or four steps after, in the lab. The entry was off a hallway
which had a usual lighting.

With a 30 inch entry and that much more wall baffle and
that much wall to wall, 12.5 square feet would be needed.
The inner wall baffle would not necessarily need reach
the ceiling as long as the ceiling itself serves by
color as a baffle.

So, anyone who would like such an entry and have 12.5 or
more square to spare can have one. For very fast light
sensitive materials, if indicated, hang a brush aside
fabric at the entry.

"I have checked it now in the a.m., at noon, and in the
afternoon with the curtains and the west door open and
I AM IMPRESSED! After sitting in the dark for 30 minutes,
one can still not see ANY trace of light."

I'm sure you're light tight. A little reminder though: The
light we see and the light films and papers see are not the
exact same. Both films and papers are VERY sensitive to
the deep blue, violet, and ultra violet. Dan

Having used the darkroom this afternoon for POP prints (exposed outside in the sun) and with the light-trap entrance at the OTHER END of the basement, I realized I need to install a safelight at the end by the entrance! I had no idea it would be so hard to walk a straight line 40 feet in the darkness . . . (we wont mention stubbed toes or bumping into walls!)

Another thing you might consider, in case of the need to exit while working with faster and/or panchromatic materials, is installing glow tape to outline the door. The material can be quite dim and still show well to fully adapted eyes, especially if you avoid direct sun exposure for 24 hours before working in the darkroom.
