Wearing a mask can be very useful and it varies depending where we are: a mask of a superhero when you're with the one you'd want to protect, a cheerful kind of a mask for those days when you don't want anyone to see you crying or you can employ a mask of childishness for you and your camera!
I know there have been a couple of mask modifications posted for the holga already but its such fun I can´t emphasize and encourage everyone out there enough to go and do their own masks right now!
Its so simple and gives great results!
What you need:
a transparent foil, for instance for overhead projectors
the 6×6 or 6×4.5 mask of your holga
your holga of course
Draw a bunch of 6×6 (or 6×4.5) squares on the foil (you can use the mask and just draw around the outlines)
with a permanent marker.
For instance design a frame, hearts, stars, a monster, whatever you can come up with!
Put the mask with the foil into its place in the holga, load film and shoot away!
Learn from my mistakes:
Keep the foil clean or you´ll have hair and dust on your pictures (can be charming though!)
Keep in mind that the mask will be reversed as you take the pic ;)
For sharper lines and masks you can print a graphic on the foil!
