Important: "Front" is where the camera obscura has its lens,
"back" is where its back wall with the small door is located.
"Left" and "right" then follow automatically. The observer
stands behind the camera obscura and points the lens to-
wards the object whose image is to be captured.
Step 1
Detach the front wall [A1, sheet 1], the left
side wall [A2, sheet 3], and the right side wall [A3,
sheet 4] from the cardboard sheets. Also detach the
octagonal base panel [C5] from the front wall, you
will need it in section C. The small disc in the base
panel [C5] should not be removed because although
it is punched during the production process it is not
needed. Fold all glue tabs backwards along the per-
forations, i.e. towards the black back.
Tip: This is how to fold the 0.65 mm thick cardboard
neatly: Place the part on a board or similar with a sharp
edge so that the perforated fold line is lying on the edge
and bend the glue tab downwards. Then fold it all the
way over and smooth the fold with your thumbnail or
a folding tool.
Step 2
All three parts have one edge with a glue tab
that is bevelled on both sides. These edges face up-
wards; the transparent viewing window will later be
glued onto them. Place the front wall [A1] in front
of you with this tab facing upwards, the black inside
towards you. Set up the left side wall [A2] at right
angles to it on the left so that its beveled glue tab
is also facing upwards. The black areas of the two
parts then point inwards, the gold-printed areas
outwards (Fig. 1). Check that the rectangular slant-
ed glue area with the 5 arrows on the inside of the
left side wall has its lower end near the front wall.
Glue the front panel in this position to the side glue
tab of the left side panel.
Important: Before drying, press the bottom and side
edges onto your work surface to ensure that they are
level and straight.
