Who said that circle images are only possible to get with the Lomography Fisheye camera? My experiment with a simple paper vignette and Diana Mini led to an unexpected result.
To be honest, I didn’t want to get such a strong effect but intended to darken the edges of the frame a little bit like the Holga 135 BC camera.
But I miscalculated a little bit and made the hole too small – using the vignette with Diana Mini, I made it 5 mm. And instead of black corners, it instead formed images with a round picture.
On the some photos it looked spectacular enough. On some images, the frames aren’t black – light came under the edge of the vignette and reflected off the paper.
You can avoid this by making a vignette from black paper. Or vice versa – to use reflection, and experimenting with paper of different colors.
Because the vignette cut off all unnecessary frames around the edges, this technique can be used in order to keep the image, only the main object. This is very useful if the shot gets a lot of unnecessary items or objects, such as for shooting in crowded places.
You can create several vignettes with holes of different diameters. If you are going to experiment in this way, please let me know about your results!
