I am part of a research group who's looking to use altered versions of some fractal wallpapers as part of our visual stimulus set. The images will be cropped a good 30-50%, and turned greyscale. The images may or may not be flipped.
Since our stimulus set will comprise of around 300 images, it is extremely difficult for us to contact every artist whose images we use. So we are wondering, since we are altering the images so much, would there be copyright issues?
