Hondiingr Handle only in total darkness.
  For il5 magazines, total darkness is requir.gd f9r taking the magazine
out of the filni can and for all handling while the magazine is outside
of ifr" can. After the last exposure has been made, rewind the film into
tine rnagazine and return  it 1o the fiIm can in total darkness'
Filters: For most applications, a filter must be used over the lerrs (or light
r""r"") to absorb ihe blue light to -E9h the film is sensitive. For gcneralpfrotog."phy, a Kooer Wi.erraN Filter No. 25 is recommended  for
this purpose.
                   EXPOSURE
Exact speed recommendations are not possible because the ratio of in-
frared tb visible radiation is variable and because photoelectric meters
are calibratecl onl;r for visible radiation. LJse a hand-held meter rather
than a through-thi:-lens tYPe.
   It is recorimended that trial exposures be made to determine prop_erexposure for the conditions under which photographs will be made.
Under average conditions, the following speeds .^u" p9 used as a basis
for determini-ng exposures'when meters marked for ASA speeds or ex-
posure indexes are used.
