Or lack thereof. This is the first shot I took with the polaroid back for my Holga. I was so worried about making sure I had everything else set up right, I forgot to take off the lens cap. Seems pretty fundamental, I know, but the thing is, the polaroid back covers the viewfinder...I had no idea the lens cap was on. At least the light leaks provide some compositional interest. And I haven't forgotten to take the cap off since.
