Checking the contents
The Ourst M 670 BW or Ourst M 670 COlOR is shipped in a
special break-proof package. Please
check that all parts are
included
as listed in the above section. Before assembly
thoroughly clean and dust all components with a cloth.
Assembling the enlarger
Place the column (2) with the column base (3) on a table and
hold the baseboard (1) against the column base (3) so that you
can push the hexagonal bolts
(13) through the backing plate
(14) and the holes of the baseboard (1) and column base (3).
Tighten these bolts with the spanner
(12) supplied. Now place
the baseboard with the column attached on the table with
the rubber feet
(20) down. Next attach the lower section of
the enlarger head (4) to the supporting stud (21) and secure
with the locking knob (22).
If your enlarger is the Durst M 670 BW, insert the lamp fitting
(9) from below into the lower section of the enlarger head (4).
Screw the 150 watt opal lamp
(10) supplied into the lamp
holder (23).
Then mount the black-and-white condenser lamphouse
(5) over
the
lower section of the enlarger head (4) and secure with
the two milled screws (24).
Below the condenser lamphouse
(5) attach the condenser (6)
supplied to the milled screws (25) provided for the purpose.
To do this, slack off the two milled screws, engage the two
cutouts of the condenser unit under the milled screws (25)
and screw the latter tight.
Plug the lead
of the Ourst M 670 BW into the socket of an
exposure timer and connect the latter to the mains supply.

If your enlarger is the Durst M 670 COlOR, fix the 100 watt
12 volt tungsten-halogen lamp (18) in the colour mixing head
(15) so that the lamp itself is between the lamp support (26)
and the retaining spring (27) with the stud on the lamp reflector
pointing down and engaged. The lamp must
be correctly
located in the lamp support which automatically centres the
lamp and so ensures even illumination.
Never touch the inside surface of the reflector
(28) with your
fingers.
From below place the blanking plate
(19) over the opening
for the black-and-white lamp fitting and secure with the milled
screw (29).
Place the colour mixing head (15) over the lower section of
the enlarger head
(4) and secure with the two milled
screws (24).
Below the
colour mixing head (15) fit the mixing box (17)
supplied with the two milled screws (25) provided for the
purpose. To do this, first slack off the milled screws, engage
the two cutouts of the mixing box
(17) under the milled screws
(25) and screw the latter tight.
Plug the lead
of the M 670 COlOR into the socket of the
TRA
305 transformer or of the EST 305 voltage stabiliser. Plug
the lead from the transformer
or voltage stabiliser into the
socket
of the exposure timer and the lead of the latter into a
mains supply socket.
In the negative carrier (7) insert the SIVOMA 35 format mask
(8) -with the lettering up -into the top section and the
SIXMA 35 mask (with the lettering down) into the lower section
of the negative carrier.
Push the negative
carrier into its opening in the enlarger head.
Fully screw the lens
(30) to be used into the lens board (11).
Fit the lens and board in the lens
carrier (31) and secure
with the milled screw
(32) so that the aperture scale is visible
from the front.
IMPORTANT:
Enclosed with the Ourst M 670 BW and the Ourst M 670 COlOR
is a diffuser and a retaining spring. These are used in the red

filter holder in place of the red filter for full-area integrated
readings with
colour analysers or enlarging exposure meters.
To fit the diffuser, push the red
filter out of its seating in the
red
filter holder, insert in its place the circular diffuser
supplied and fit the retaining spring. The diffuser now swings
into
the light path for full-area meter reading.
Centering
the lamp in the Durst M 670 BW
Before inserting a film, precisely center the opal lamp
for even
illumination
of the projected image on the baseboard. Proceed
as follows:
Switch on the enlarger lamp with the lens at full aperture
and
without a negative. Check the projected area for shadows
or darker sections. If necessary centre the lamp by pushing
the
lampholder (9) up or down or by turning it till all dark
spots disappear. Then secure the lamp holder (9) in the desired
position by screwing
tight the milled screw (29).
Before adjusting the lamp
check that you are using the
correct combination of lens, condenser and film masks or
glasses for the film size being enlarged.
Inserting
film strips or single negatives
Dust and
fingerprints on films show up disturbingly in
enlargements. So before enlarging clean any
dirty negatives
with a sable
or antistatic brush.
Remove fingerprints by gently
wiping a fluffless cloth. Use a
film cleaning fluid
for more persistent dirt. Insert only fully dry
negatives in the carrier. Take special care in cleaning so as
not to scratch the film's emulsion layer.
To insert
single negatives fully pull the carrier out of the
enlarger head. Locate the single negative precisely over the
cutout to utilise the full image area. Then close the carrier
(which now holds the film securely in place) and push it into
the enlarger head.
9

When you insert film strips the negative carrier can remain in
the enlarger head. Slightly raise the top section
(33) of the
negative carrier; it then stops in its open position. Now slide in
the film strip from
the front. It is correctly located when the
strip abuts the locating pins
(34) and the full film area appears
projected on the baseboard once you switch on the lamp.
Then close the negative carrier pressing the key
(35) at the
top. Preferably cut the film into short strips to avoid scratching,
Turn the locating pins
(34) into their front position for 24 x 36
mm films or into their rear position for No. 120 or 220 rollfilm.
The pins
(34) must be turned fully forward or back, otherwise
the negative carrier does
not close properly and could jam
in the enlarger head.

** The 50 mm Schneider Componar C f/2.8 (new version in
plastic barrel) requires the SIRIOTUB
39 lens board.
NOTE: Lenses with M25 screw thread
fit the above lens boards
via a FLARING reducing ring (available separately).
Vertical adjustment
Raise or lower the enlarger head with the knob and crank (36)
of the carriage. A rack-and-pinion drive ensures smooth
and precise vertical adjustment.
The wide profile column
(2) makes the enlarger very rigid.
The column carries scales in cm and inches
(37) and shows
magnifications
(38) for the 50 mm, 80 mm and 105 mm lenses.
Focusing
Focus by raising or lowering the lens carrier via the friction
drive operated by the focusing knobs
(39) at each side. Focus
at the full lens aperture on the paper holder
or masking frame
placed on the baseboard. Insert a sheet
of white paper of
the same size and thickness
as the enlarging paper to be used.
Ideal is the back
of a developed print. Rotate the focusing
knob until the image projected on the baseboard appears
sharpest. After focusing you may need to readjust the image
size (and refocus).
10

The white-light setting of the Durst M 670 COLOR
To facilitate focusing, the colour filters can be swung out of the
light path with the white-light lever (40). The white-light signal
(47) shows when the filters are swung out. After focusing
swing the filters back into
their original position again with
the same lever (40).
Part enlargements
Even expert photographers do not always manage to frame
their picture exactly during the camera exposure. Such
framing
or cropping is only possible during enlarging. This
way you can often obtain several interesting enlargements
from one negative or transparency. Adjust the magnification
to bring the required image portion within the masking frame
area on the baseboard.
Giant enlargements
For giant enlargements
project on the floor or the wall.
For floor projection unscrew the hexagonal bolts
(13) and turn
the column base (3) with the column
(2) and the enlarger head
round through
180". Then refit the hexagonal bolts.
Preferably weigh down the baseboard to prevent the enlarger
from tipping over.
For wall projection release the locking knob
(22) and turn
the enlarger head
(15) through 90" till it engages. Secure the
enlarger head in this position by tightening the locking
knob (22).
Correcting converging verticals
To
correct converging verticals release the locking knob (22);
you can now
tilt the enlarger head. Tilt the masking frame
with the enlarging paper in the opposite direction. Stop down
the lens sufficiently to obtain an image sharp over the whole
paper area.
Copying
With conversion kits (Order codes VEGAREPRO and
UNIREPRO
670) you can adapt the Durst M 670 SW or Durst
M
670 COlOR for copying.
22----
11

42
The VEGAREPRO kit consists of a copying film holder
(Order
code SIRIOREP) and the COPYLAM 4 lighting system.
The SIRIOREP
(41) takes film holders for 6.5x9 cm
(2
1
12 x 31 /2 in.) sheet films. For further details see the
instructions with the Ourst SIRIOREP copying film holder.
IMPORTANT: When copying with the Ourst M 670 SW and
Ourst M 670 COLOR you focus and check the field of view
on the baseboard.
The UNIREPRO 670 kit consists of a camera arm
(42) (Order
code NERIOCAM) and the COPYLAM 4 lighting system. With
this the Ourst M 670 SW or Ourst M 670 COLOR can serve as a
copying stand for a normal still camera. Remove the enlarger
head and attach the camera arm to the supporting stud
for
the enlarger head.
The COPYLAM 4 lighting system takes four reflector floodlamps
of 100
or 150 watts (Order code FLULAM 100 or FLULAM 150).
Black·and-white enlargements with the Ourst M 670 BW
Follow this procedure
for making a black-and-white enlarge-
ment with the Ourst M 670 SW:
(a) Place the negative in the negative carrier with the
emulsion side
down;
(b) Switch off the room light and switch on the enlarger lamp;
(c) Adjust the magnification and focus the image with the
lens at full aperture;
(d) Stop down the enlarger lens by two stops and swing the
red filter
(43) into the light path;
(e) Insert the paper in the masking frame and
check the image
location (the red filter protects normal black-and-white
enlarging papers);
(f) Switch off the enlarger lamp and swing the red filter out of
the way;
(g) Make a test exposure
to establish the correct exposure
time. For instance make
an exposure series of 1, 2, 4, 8,
16 und 32 sec. with a Ourst test strip holder or a Ourst
multi-print masking frame;
(h) Process, rinse and dry the test strip. Select the
correct
exposure time from this test and set the exposure time
accordingly.
Note: You can also make black-and-white enlargements with
the Ourst M 670 COLOR by setting all filter dials
(44) to zero.
The diffused light is equally suitable
for black-and-white
enlargements; by using a more contrasty paper grade you
allow for the lower contrast
of the M 670 COLOR lighting
system. This has certain advantages: The diffused light
suppresses the effect of dust and scratches and yields
enlargements of a greater tone range.
Note especially that diffused lighting does not affect image
sharpness. For sharpness depends exclusively on the quality
of the negative and of the enlarging lens.
Colour enlargements from
colour negatives or transparencies
with the Ourst M 670 COLOR
The procedure
for making a colour enlargement starts with
a zero correction
print involving the following steps:
(a) Place the film with the emulsion side down in the negative
carrier (emulsion side up
for enlargements on Kodak
Ektaflex and Agfachrome Speed materials);
(b) Move all
filter dials to zero;
(c) Switch off the room light and switch on the enlarger lamp;
(d) Select the enlarged image size and focus (with the lens
at full aperture);
(e) Stop down the enlarger lens by two stops (with high-speed
enlarging papers you may have to stop down by three
stops);
(f) Switch off the enlarger lamp;
(g) Establish a correct exposure time by a test exposure
using a series of times (for instance of
1, 2. 4, 8, 16 and
32 sec.) with a Ourst test strip holder or a Ourst multi-print
masking frame.
Process, rinse and dry the test strip. Then select the section
with the
correct exposure time on the strip and set this
time
on the exposure timer. If none of the test exposures
yields
an image of correct density take the best result as the
starting point
for a further exposure correction:
Exposure correction
with colour negatives
Print too light: Increase exposure time
Print too dark: Reduce exposure time.
Exposure correction
with colour transparencies
Print too light: Reduce exposure time
Print too dark: Increase exposure time.
Usually the test print will also show a
colour cast.
43--~
12

You now have to eliminate this colour cast by an appropriate
filter correction. The
colour mixing head has three built-in
colour filters
for this purpose:
(1) Yellow (Y)
(2) Magenta (M)
(3) Cyan (C).
The other three primary colours (red, green and blue) are
obtained by combining two filter colours in the colour mixing
head:
Red: By setting equal values of yellow and magenta
Green: By setting equal values of yellow and cyan
Blue: By setting equal values
of cyan and magenta.
For example:
10 red 10 yellow + 10 magenta.
Before you use these filters
or filter combinations you must
know something of their effect. So remember the following
filter rules:
Filter correction effects when enlarging
colour negatives
Rule
1:
A colour cast in an enlargement from a negative is removed
by a
filter or filter combination of the same colour. In an
enlargement from a positive transparency a cast is removed
by a
filter (or combination) of the complementary colour.
Rule
2:
Excessive correction causes a cast in the complementary
colour; reducing that filtration again restores
colour balance.
Rule
3:
Use only one or two, never three filter colours. A third filter
colour adds grey density which does not modify the filter
effect but only increases the exposure time required.
Rule 4:
The stronger the cast, the higher must
be the corrective filter
density.

Rule 5:
The higher the filter setting, the more the exposure time
increases. This applies especially to magenta and cyan.
Rule 6:
Preferably mark the filter setting, exposure time and lens
aperture on the back
of every test and every print.
Rule 7:
Judge the colour effect by daylight or by a daylight-matching
light sourCe.
Note to Rule
5:
To ensure correct exposure of subsequent prints after
increasing the
filter settings, you have to recalculate the
exposure time
for every change in filter value. Use the
exposure factors listed in the table below, entering them in the
following equation:
(F1 x F2 x F3) new
T (new) = T (old)
x· (F1 x F2x 1=3) old
T (new) new exposure time
T (old) = old exposure time
(F1 x F2 x F3) new new exposure factors
(F1 x F2 x F3) old = old exposure factors

10 x 1.08X1.15X1 = 12.5 sec.
Example
2:
New filter settings 20 00 00
Old filter settings 20 10 00
If the old exposure time was 20 seconds, what is the new time?
In the table look up the filter factors
of the new and old filter
settings and enter them in the equation:
20 x
1.08x1.00X1.00
T (new) 17.4 sec.
1.08X1.15x1.00
Note that the magnification must not change while you are
making the filter test. After every change in the filter setting
make a new test print until you have the best
filter combination.
Then make the final enlargement. Using a colour analyser
or meter greatly simplifies and speeds up this procedure.

Black-and-white enlargements
on variable-contrast papers
with the Durst M 670
COlOR
With variable-contrast papers you can enlarge all your prints
on a paper of single gradation. The contrast response is
controlled by suitably filtered exposing light. With a yellow
filter the gradation becomes flatter, i.e. the print softer; with
a magenta
filter the gradation becomes steeper and the print
more contrasty.

different equivalent paper grades:

To fit the black-and-white condenser lamphouse on your
Ourst M
670 COlOR, first remove the negative carrier from
the enlarger head and slack off the two milled screws
(24)
below the enlarger head (4). Then remove the colour head (1S)
from the enlarger together with the mixing box.
Unscrew the milled screw and remove the blanking plate.
From below insert the lamp holder
(9) in the enlarger head
and screw the opal lamp
(10) supplied into the lamp holder (23).
Mount the condenser lamphouse over the lower section of
the enlarger head and secure with the two milled screws (24).
Attach the condenser
(6) supplied to the condenser lamp-
house by engaging the milled screws
(2S) in the cutouts on
the condenser housing. Secure the two screws.
Push the negative carrier into the enlarger head and plug
the lead
of the enlarger into the socket of an exposure
timer, connecting the latter to the mains supply.
Before enlarging black-and-white films centre the lamp
as
described for lamp centering with the Ourst M 670 BW.
Accessories for colour enlargements with the Ourst M 670 BW
If your enlarger is a Ourst M 670 BW and you want to enlarge
your own
colour films, you can convert the enlarger to a full-
scale
colour unit with the separate ClS 670 conversion kit.
This kit consists of:
A
colour mixing head
- A TRA
30S transformer or EST 30S voltage stabiliser
- A 100 watt
12 volt tungsten-halogen lamp
- A mixing box
for films up to 24 x 36 mm.
To
fit the ClS 670 colour conversion kit on your Ourst M 670
BW, first remove the negative carrier from the enlarger head.
Then slack
off the milled screws (24) and remove the
condenser lamphouse
(S) from the lower section of the
enlarger head. Unscrew the opal lamp (10) from the lamp
holder (9). slack off the milled screw (29) and pull the lamp
fitting out
of the enlarger head. Cover up the lamp opening
by fixing the blanking plate from below
so that no light
can emerge when you use the colour mixing head.
Fit the COLAMP 100 S tungsten-halogen lamp
(18) in the
colour mixing head (15) so that the lamp is located between its
support
(26) and the retaining springs (27) and so that the
16

----15
-----26
27
spigot on the lamp reflector points down and engages.
Correct seating of the lamp in the lamp holder is important
as this automatically centres the lamp and ensures even
illumination. Never
touch the inside surface of the lamp
reflector (28) with
your fingers.
Place the
colour mixing head complete with lamp over the
enlarger head and secure with the two milled screws (24).
Fit the mixing box (17) supplied underneath the colour
mixing head with the two milled screws (25). Slack off the
screws. insert the mixing box with its two cutouts under
the
screws (25) and secure the latter.
Push the negative
carrier into the opening provided for it on
the enlarger head. plug the lead
from the colour mixing head
into the
socket of the transformer or voltage stabiliser and
plug the latter into an exposure timer.
