Assembling and Operating Horseman 450

 .  Assembling Camera
 Fix the camera on a tripod or a stand as shown in Photograph 1.
 Use either a larger (3/8"'l or a smaller (1/4"1taphole on the camera
 base according to the screw diameter of your tripod.
 There are a number of ways of assembling the camera as the camera
 may be assembled freely to meet any photographic requirement.
 The following is the standard method of assembly.
 (1) Release the lock for the swing movement on both the front and
     rear Supports (8). Turn the L Supports g0". The operating
     knobs for the camera movements should be on the left and the
    swing indicator (10) at the "0" position. Lock both Swing
    Lock Levers to secure L Supports as shown in Photograph 2.
 (21 Extend the bellows rearward and afix it to the Main Frame on
     the Rear Standard by using Slide Locks as shown in Photograph
      3. The camera assembly is completed.


o Attaching Lens
A Blank Lensboard is included with the Horseman 450 camera.
 The Lensboard should be bored to match the shutter diameter of the
 lens that you want to use. lf the lens is mounted on the Sinar
 Lensboard,  it can be mounted on the Horseman 450.


.  VerticaUHorizontal Conversion of the format
Release the Slide Locks (26) and detach the Supporting Frame.
Turn the frame to the vertical or horizontal position and attach
 it again by working the Slide Locks.



o Focusing Operation
Focusing is done by working the Focusing Knobs (2) on the Stand-
ard Base (7). The usual method of focusing is to move the rear
standard, however focusing can also be accomplished by moving the
front standard. For closeups and copying, set the magnification by
moving either of the standards, and focus by moving the entire
camera assembly with the Focusing Knob (2) on the Base (1).



  Camera Movements
  (Common          to Front and Rear Standards)
(11    Tilt:  Loosen the Lock Knob for Tilt (19), turn the Main
   Frame and lock it in position when the desired angle is set.
   Amount of rotation is indicated on the Scale for Tilt (20).
QI Swing: Loosen the Lock Lever for Swing (8), turn the L
    support and lock it in position when the desired angle is set.
   Amount of rotation is shown on the Scale for Swing (9).
(31  Rise/Fall: Loosen the Lock Knob for Rise/Fall (16) and turn
    the Knob for Rise/Fall (15). Amount of movement is indicated
     in mm on the Scale for Rise/Fall (17).
(41  Lateral Shift: Loosen the Lock Knob for Lateral Shift (13)
   and turn the Knob for Lateral Shift (12). Amount of movement
     is indicated in mm on the Scale for Lateral Shift (14).
                                               -2-

o Using Spirit Level
     The Spirit Level is a revolving type and may be used for both lateral
     and vertical directions. This conversion is done by turning the Level
      manually. The Spirit Level may be attached in either of the two
       Spirit Level Bases on the upper and lower sections of the Main
      Frame. Pull the level out to detach it when changing the position.


    o Attaching Film Holders
        Lift the edge of the Groundglass Frame slightly and insert the film
       holder until  it stops. The Polaroid 545 Film Holder, the Horseman
       Optical Exposure Computer and other appropriate sheet and roll
       film holders may also be inserted in the same manner, as shown in
       Photograph 4.
     When attaching the Polaroid 405 Film Holder*, push simultaneously
      the two Spring Latches (30) on the longer side of the Groundglass
      Frame to detach the Frame by sliding it as shown in Photograph 5.
      Then, attach the film holder using the two Accessory Holders (28)
      on the Supporting Frame.


    o Taking 6 x 9 cm, 6 x 7 cm photographs
     When taking 6 x 9 cm or 6 x 7 cm photographs on roll film, attach
                                       454 directly to the camera      the Horseman Roll Film Holders 451 -
                                               on the Horseman      or attach the Horseman Roll Film Holders 1 - 4
      Rotary Back ll*. In attaching these to the camera, detach the
       Groundglass Frame and affix the film holder or the Rotary Back
       using the two Accessory Holders (28) on the Supporting Frame.                                                                   *,     When attaching the accessories indicated by   turn the Main Frame
      180o. For details, see the following "Variations of Assembly",
       Section (6).




   Variations of Assembly


     The following six sections are alternative methods of assembling the
     Horseman 450. (The Lensboard side is rendered front and the
      Groundglass side rear. Left and right are the directions when viewed
     from rear.)


    1  Left and Right of Focusing Knob on Base
        The Focusing Knob on Base is situated at right at the time of
           delivery. lf you wish to set the Focusing Knob on Base on the
          opposite side of the Focusing Knobs on the Standards (see
          Section (4)), you can simultaneously change magnifications and
          focus with both hands. In this case, loosen the screw of the
          Monorail Stopper Plate to detach  it. take the Base from the
          Monorail and reverse it. Then reattach the Base to the Monorail.
           This procedure  is common to the Sections 2 , 3 and 4                                www.butkus.us.                                                           -3

I

Front and Rear, Surface and Back of Monorail
 The rear of the Monorail is set at "0" at the time of delivery.
 As the back of the Monorail has no calibrations. you can write
 in your own marks or calibrations.

 Inside and Outside use of Lock Lever for Swing.
The Lock Levers for swing are set to face outside at the time of
delivery. The levers can face each other by interchanging the
Standards.

 Left and Right of Focusing Knobs on Standards
 The Focusing Knobs on the standards are situated on right side
 at the time of delivery.

 Left and Right of L Supports.
 Turing the L Supports left or right may be easily done as the
 L Supports can be rotated 360o by detaching the Bellows and
 releasing the Lock Levers for Swing. After turing the L Sup-
 ports, rotate the Main Fradre (2) 180' in order to return the
 Main Frame to the proper operating position.

 Positioning Main Frames at Front, Rear and Center of L Sup-
 ports.
 Both Main Frames are positioned at front of each L Support
 as shown in Photograph 6. Only when the Main Frame on the
 Rear Standard is positioned at the front position, the tilt/swing
 axis and the focal plane coincide, preventing the shift of focus
 and picture image on the center line of the picture frame by the
 tilt and swing movements.
 While maintaining the front offset of the rear Main Frame,
 detach the Bellows and Lensboard from the front Main Frame,
 loosen the Lock Levers for Tilt and turn the front Main Frame
 180o. The front Main Frame is positioned at rear of the front L
 Support and the front and rear Main Frames come to their
 closest position as shown in Photograph 7. In this case, the
 flange-focal distance is the shortest at 60 mm, and a 65 mm
 super ryide angle lens may be used on a flat lensboard, without
 using a special recessed lensboard, though a wideangle bellows
 should be used. Maximum bellows extenslon is acquired by
 setting the front Main Frame at the front position and the rear
 Main Frame at rear position as shown in Photograph 8.
 The Main Frames may also be positioned at center of L Sup-
 ports, if necessary. Turn the Main Frame g0" to set it laterally,
 loosen the two Lock Knobs for Main Frame (23) and detach
 the frame by sliding it from L Support as shown in Photograph
 9. Then, insert the Main Frame from the opposite side (to the
 direction opposite of the arrow on the. frame) as shown in
 Photograph 10, and lock the Frame with the two Lock Knobs.
 lf the Main Frame is inserted to the direction of the arrow, it
 is placed in the offset position. The shift of picture image by
 the tilt/swing movements may be minimized by utilizing these
 three positions of the Main Frame on the front L Support
 (front offset, centering and rear offset).

When using the Horseman Rotary Back ll, set the rear Main
Frame at rear of the L Support. Though the Polaroid 40b Film
Holder may be used for any position of the Main Frame, the dark
slide operation is the easiest when the Main Frame is at the rear
offset.

Interchanging and Detaching Groundglass and Fresnel Lens


 lf the Fresnel Lens is included with the Horseman 450, it
 is fixed in front of the Groundglass (to the side of the lens).
 Follow the procedures'below when interchanging Ground-
 glass and Fresnel Lens or detaching the Fresnel Lens.

o Detaching (See Photograph 11)
 Loosen the six screws to detach the Groundglass Latches
 (A). The Groundglass and the Fresnel Lens are separated
 by detaching the upper and lower Fresnel l-ens Latches (B).
 Be sure not to lose the Spacers (C).


 .  Attaching
 1 Attaching Frecnel Lens
     Align the grooved surface of the Fresnel Lens with the
     sandblast surface of the Groundglass (the letters of
   "HORSEMAN"on the Fresnel Lens are viewed correctly
   on the Groundglass) and attach it with the Fresnel                                                            Cuations in Use    Lens Latches. Place the Spacer correctly on the
     Groundglass Frame and put the Groundglass on it, with        1 Be sure to release the lock before operating each    the Groundglass on the upper side. Fix the Ground-                                                                   camera movement. The forced operation in the locked
     glass Latch with the six screws (the Groundglass may                  position may damage the driving and locking mecha-
     be broken  if the screws are fastened exessively).                                                                                  nisms.
                                        2 Refrain from the disassembly beyond the limits of the
                                                                      assembly and disassembly of each module as described
                                                                                          in the instructions.
    Attaching Groundglass without Fresnel Lens.              3 Refrain from using organic solvent such as lacquer/
    With the smooth surface facing out, place the Ground-                 thinner and acetone in cleansing Knobs and Fresnel
    glass on the Groundglass Frame without using the                  Lens, because they are made of molded resins which

                                                                                   cloth.
                                        4 In cleansing the sandblast surface of the Groundglass,
                                                          wipe gently with a soft cloth soaked with a small

    in high-magnification closeups and photomicrography
    because focusing is done with the bright aerial images.
   When using the Aerial-lmage Groundglass, the Fresnel
    Lens is not used. Place the Aerial-lmage Groundglass on
    the Groundglass'Frame(without  using the Spacer)and fix
       it on the frame after removing the rubber on the under-
    side of the Groundglass Latches. ln focusing with the
    Aerial-lmage Groundglass, use a magnifier with an
    eyesight adjustment device. Adjust the eyesight until
    the scale (in 0.5 mm) in the aerial-image section at the
    center of the Groundglass is viewed most clearly.
    Focusing is correct when both the scale and the aerial-
    image of the subject are viewed clearly.
