Hi MF3D gtoup,
I am new to Medium Format 3D photography. I just bought a 3D Holga.
Before trying it out, I decided to do some spray painting with flat
black. To this end I removed the front plate. Here is how I did it.
There are eight hidden screws, one under each battery label and two
under each sponge. Remove these and the front plate comes off. Now you
can examine the shutter mechanism as well.
