I needed to add contrast to an image for a screen print. I asked Mandy in the Mac room if she could help me. The image was taken from some photographs of a black and white lino and the lighting and position I took it wasn’t very good as a shadow was behind it and the white was quite yellow because it was on a clear lino.
I uploaded the image to Photoshop and Mandy told me to go to select-colour range and deleted the white which made the white whiter. Then concentrated on making the black darker. This was the result.
