Hello all,

I've just finished developing a roll Kodak High Resolution Aerial Copy
film.  I had cut and rolled a strip of it and put it in my old
Rolleiflex.  I took a series of shots of the landscape in front of my
house to get an idea of the film speed. The resulting negatives are
certainly interesting.  The cloudy sky is very dense compared to the
ground, which I expected.  But something strange has happened I cannot
explain.  I have much more detail of the houses etc. at 8 and 4 sec and
also at 1/2 sec.  At 2 sec and especially at 1 sec the ground detail is
almost gone.  This film has no antihalation backing.  To look at it it
is yellow and almost transparent.  Could this be halation?  I have no
idea what halation looks like on the film.  If anyone is curious, the
images that look like they are exposed about right have amazing detail. 
I didn't know the little Tessar in my Rolleiflex was that good.  I will
let you all know what happens when I try to print these.  That should
happen in a couple days.  I have 500ft. of this stuff, and my plan was
to cut a bunch of 4x5 sheets from it.  Looks like it works well at about
ASA 2-6.  I developed it in Rodinal for 10 min at 20 deg C.
