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.
