We are a small group of like-minded people and meet every 3. Wednesday of odd-numbered
months to pursue our hobby. Here we will try to show what we craft.
Nous sommes un petit groupe de personnes, partageant les mêmes idées et nous nous
réunissons tous les 3 mercredi des mois impairs pour poursuivre notre passetemps.
Ici nous essaierons de montrer ce que nous fabriquons.
Wir sind eine kleine Gruppe von Gleichgesinnten und treffen uns jeden 3. Mittwoch von den
ungeraden Monaten um unser Hobby zu betreiben. Wir werden versuchen, hier zu zeigen
was wir so basteln.
Welcome

High-dynamic-range imaging (HDR)
is a technique used in digital
image processing to combine a series of image
s with different
exposures
(normal, underexposed,
and overexposed)to produce one
image with an optimal overall
exposure range.
•
A HDR tool creates a new image with a greater dynamic
range of
l
umino
sity
.
•
Ideally, the images you use with the HDR
tool
will include a well-
balanced range of highlights
and shadows
•
HDR is
useful when you have a scene with very large differences in
luminosity, i.e. between dark shadows an
d bright areas.
•
For model railroad photography this could be useful at exhibit
ions,
where the lighting is not ideally
balanced.

For the focus-stacked images,
I
have
used
a new camera OM-System
OM-1
Mark
II.
•
The shooting
of the
series
of pictures
with different
focus settings
is
automatically
adjusted
by the
camera
with a minimum
delay
time.
Hence,
in this
mode the pictures
can be
taken with the camera
handheld.
The speed
depends
mainly
on the camera’s
processor
and on the lens speed
for setting
the
focus.
•
Processing
of the series
of pictures
is done either
internally
in the camera or externally
in a
modern photo processing
program.
I
typically
use
ACDsee
Photo Studio
Ultimate.
There
are other programs
available
for even
’higher
quality’
focus-stacking
processing,
such as
Zerene
or Helicon
(
not free) or Focus-Stack
(
free on GitHub).
•
High dynamic range
pictures
can also
be shot and processed
with
the new camera
while
handheld. W
ith an older camera
(
as my Olympus
E-330) a series
of images
was
taken
while
adjusting
the exposure
time
manually
(
camera must be on a tripod)
from
one shot
to
the
next.
•
From my experience,
the best
software
program
available
is
the Photomatix
Pro 6 or
7.
With this
program
the
HDR
picture
can be fine-tuned,
that
is
not available
in the camera.

Bot
h techni
ques are used mainly
in near field
or close-up
phot
ography to exte
nd the
picture’s depth of field
(
DOF),
while keeping a large lens
aperture (
short DOF).
For focus
br
acketing the came
ra will
take a predefined ser
ies of pi
ctures
of the same
obj
ect or scene,
while shifting the focus in-betw
een the pictur
es w
ith a selectable
interval.
The camera
will
start with the focused
on parts of the object closest to the lens,
and shift
the focus
gradually
to parts further away from the lens,
i.e. from ‘front’ to ‘back’.
Focus
stacking
works
in
a simila
r way,
with the only
difference that the ca
mera starts a
focusing somewhat closer
to the lens as the closest
part of the object.
Normally
an initial or reference focus position is
adjusted manua
lly.
After the series of pictures
(
typ. 10) a
re stored in the camera’s memory,
the in-
camera
processing starts (
w
hen available).
As
result a single
picture is obtained,
wher
e the DOF
covers
the total depth of the photographed object.
If
the camera does not have
this processing
capabilities,
the series of pictures can be
processed
using
an external photo processing
program.
Several
algorithms
for
detecting
the
focus
position
