Ok, if you don't know by now I am a big toy camera buff. Many
people always wonder about the sprocket holes on my images, and I will tell
you it is no PS trick. 35mm film is loaded into the Holga camera and the
sprocket holes are a normal part of the image process. Of course 120 medium
format film can also be used in the camera without the sprocket holes, but
for some compositions the rectangular image ratio of 35mm is beneficial and
the sprocket holes add a nice finishing touch to the final print. Enjoy!
