Acetate contact printing

This was an idea of mine in which you turn a digital photograph into film, and print it onto photographic paper to what, I feel, to create a more artistic approach to the image. The first thing I was tasked with doing was choosing a suitable image to then edit and print. I was required to put the image in black and invert the image so it becomes a negative. I then printed the image but before doing so I put a A4 sheet of acetate in the printer. As the images came out I was happy with the quality of the image however I quickly noticed that there were horizontal line scratched through the sheet, therefore was not satisfied with the image overal. I then put the acetate onto photographic paper with an exposure of 5 seconds at an apeture of f5.6 after creating a few test sheets. After developing the quality and exposure of the image was almost perfect however, the scratches on the film ruined the image to the point of them not having much use.

Test strip, to which I decided the photograph need 4.5 seconds at an aperture of f5.6.
