From the Editor
September, as some
of you may remember,
is a busy month for
me. Grand Rapids
hosts
ArtPrize, in
which I have once
again entered a
digital artwork.
It's also my wife's
birthday, the same
day this newsletter
is due, not to
mention the opening
of hunting season.
So many things to
do, plus the return
of school has only
slowed crime a
little. The weather
took a turn towards
the cool, and it's
just a matter of
time until we have
snow once again.
This month issue is
focused on latent
prints, we have a
couple of things
from Hayden, showing
some photography
techniques as well
as a couple of
articles on latent
processing.

President's Message
Greetings!
As
you know from previous
newsletters we had a
vendor booth at the IAI
Conference in Rhode
Island this year. While
the attendance was not
as good as previous
years out booth was well
attended. Most that
stopped at the booth
were not even aware we
existed so it was a
success for us in just
getting the word out.
Even Dr. Henry Lee
stopped at the booth and
we visited for a while.
I have known him for
over 20 years and taught
with him in the past. He
took some of our flyers
to pass out in his
classes and symposiums.
It was an expensive trip
but one we felt was
required to help promote
ICSIA.
Our CSI Conference in
May 2014 is shaping up
well. We are getting a
lot of inquiries and
hits on the conference
web pages from a variety
of states and countries.
We even received a
Conference Registration
form from Liberia,
Africa! This should be
an interesting CSI
conference with an
opportunity to network
directly with CSI from
all over the world! But
we are limited in space
so if you intended to
attend the conference I
would not wait too long
to register.
We are still accepting
presentation and
workshop proposals so if
you have one or know of
someone that should be
here please let us
know. Our Conference
agenda will not be
formalized until later
but the tentative topics
are posted on the web
site at: http://www.icsia.org/conference/agenda.html
Those listed with a
presenter have been
confirmed.
In the last issue of the
Examiner I had a short
article on lighting of a
footwear pattern. We
received a concern from
a member that the image
was not properly
photographed by the
standards we use to
certify. In other words
it was a poor image to
be displayed. While we
do attempt to deliver
the best we sometimes
have to work with what
we have. The images that
were posted were taken
by me over 30 years ago
and the “standards” were
different then. A 6 inch
ruler was common
practice to use as a
scale. The reason why it
was common practice then
was that we were still
in the film days and the
person making the
enlargement from the 4 X
5 negative would simply
lay the 6 inch ruler on
the paper and match the
size. The images are
also cropped from the
original images which I
did not make note of in
the article. It was an
unusual lighting
condition that caused
the two images to look
so different that I felt
the information needed
to be shared. Sorry if
this has caused anyone
to think otherwise but
we will always do the
best we can to share
information with the
members.
If any of you have
photographs to show
things such as this or a
new technique or an old
one or one of your CS
vehicle, patches or
crime scene that you
want to share with us
please do not hesitate
to send Daryl the
information to be shared
with others. We need
the members to be
active.
Stay safe!

Processing is
a Process
by Daryl Clemens
If you take a look at
Dick Warrington's
article in the side
column, you'll see that
he talks about decision
making when you approach
latent processing at a
scene. In it he talks
about how not printing
certain items can leave
you open to questions at
trial, which is
certainly true. However,
just because we don't
powder an object, or
bring it back and
superglue it does that
mean it wasn't
processed?
It is important to
remember that the reason
that we refer to the
search for latent
fingerprints as
"Processing" is because
there is a process
involved. Some people
approach fingerprint
development with the
attitude that they are
simply going to apply
powder to the surface
and see if anything
shows up. There are, or
should be, several steps
involved in determining
which (if any) technique
will be applied in a
particular search for
fingerprints.

On the Web-

Nano-particle fingerprint
powders Interesting
discussion on the new
nanoparticle fingerprint
powders. If you scan down,
you'll see a response from
Allen Miller of Forensic
Source who will be supplying
these powders in the US.
Michele Triplett's
Fingerprint Dictionary
Is there a fingerprint
related term you are unsure
of? You can find it here.
Wikipedia has
quite a long entry
on fingerprints.
And, while one must
always be careful
with Wikipedia
entries- in that
they may not always
be perfectly
accurate, it's
pretty good and
includes information
on numerous
fingerprint related
topics and quite a
selection of links
to source materials.

Axial Lighting
by Hayden Baldwin
Axial lighting
technique helps
reduce glare
from occurring
on a highly
reflective
surface like
glass, rear view
mirrors, chrome
objects, floor
tiles, CD or DVD
and more. Axial
lighting is an
excellent
technique for
photographing
unenhanced
latent prints on
reflective
surfaces.
