Creating a blur effect is easy to do with little equipment.
Digital single lens reflex (SLR) cameras allow you to change the lens to achieve a better shot depending on the subject. SLRs have many different functions and modes to create effects on images, but creating blur around just the edges of an image is often attained in software such as Photoshop post-production. If you would prefer to create this effect directly while taking the shot, the old-fashioned way is quick, requires little expertise and costs hardly anything to achieve.
Instructions
1. Place your camera lens on top of the acetate film. Trace around the lens with a marker pen.
2. Cut out the circle shape. Stick four small pieces of clear tape -- one each at the top, bottom and each side of the acetate and attach to the rim of the lens.
3. Cover your finger with petroleum jelly. Carefully smear all the way round the edge of the acetate film.
4. Take your picture and you should have acheived a blurred edge. If the image is not blurred enough around the edge just add more petroleum jelly to your acetate film.
