- Hold peephole against rim of camera lens.
- Set camera to “macro”. (the image is actually displayed on the inside face of the convex lens of the peephole. The camera must focus on the foreground image rather than the background image.)
- Zoom in to the point that the viewable “circle” is framed almost evenly.
- For best results, brighter lighting will avoid unwanted noise (grain)
- Enjoy and have fun.
You can buy a pricier model with the Lomo label on it (and if you go looking, you’ll find a “peephole reverser” which is probably useless for your photography…probably). Henry Gordon Dietz offers a lot more info.
Above is my first experiment with a peephole fisheye and my cheap video camera.
