The standard of photography is rectangles, straight-edged images. It's just an arbitrary standard. The way I print mine, and the way the Holga sees, is not that way. So I am playing on that even more by cutting them out in this round way and trying to open people up to different ways of seeing the world and presenting photography.
But also to me, the Holga, the way these images are, that they are sharp in the center and they vignette in the corners is more how we really see. When you're looking at the world, you're not seeing a scene that is sharp all the way to the edges and bright all the way to the edges and has straight lines. You're seeing something sharp in the center and then the rest of it is all kind of blurring out.
