I have a test image which is monochromatic (black/white), is a grid
pattern and shades from black on the left to white on the right which I
have been using for some Unsharp Mask experiments. In order to extend
these experiments I would like to change the test image to a coloured
monochromatic image (red/white, green/white and blue/white). Is it
possible to change this test image to a coloured image or will I have to
hunt around to either find or make new images?
Thank you for any useful advice.
