How I improved the visual

I wanted to develop the paper lens caps I made,  so that I could create a stronger/clearer image.  I created black circles on a word document at 3.6cm and then put white symbols or words in the middle.  They looked liked this....

I then printed the circles onto acetate....

Whereas the images inside the circle on the lens cap weren't clear, now the image was much clear and this created a better image and visual for the audience.  I was also able to create a new effect whereby I shot through the lens cap.  This was possible because the acetate was more transparent than the card.
