Step 2: Dismantle the camera,
To remove the top of the Holga, we first need to remove the film advancing knob.
Carefully slide a thin screwdriver under the knob, and rotate it slightly to allow you to get a firm hold, pull straight up to break the bond between to knob and the advancing spool. The glue is strong, but also cheap, so can be easily broken.
Once you have this removed you will see two small screws, these plus another screw on the opposite side need to be removed also.
Lift the entire top section straight up. If you have one of the versions with a flash, you will need to make sure you do not loose the little black plastic switch.
Be sure to discharge your camera flash fully, so as not to shock your self on the flash circuit.
