The pinhole photography technique has has some interesting features, which can be used in wedding photography.
1. Focus from zero to infinity, eg wedding photos, the photographer can be in the foreground sharp, huge rings and many more equally sharp.
2. Spy character: the camera can be made of boxes of matches, beer cans, or almost anything and placed anywhere.
3. Very wide angle and lack of distortion, as in the fish eye.
4. Long time exposure pictures of wedding photography can be used as an advantage. For example in a busy and crowded urban landscape. With only the newlyweds and the buildings not moving.
5. Sooft images perfect for wedding photography.
6. Fashionable and abused in wedding photography image vignetting comes free with a pinhole camera.
