The artist Penelope Umbrico is a prolific practitioner with a large catalogue of work presented on her site. Her use of appropriation of other peoples images for me is one of the things that stands out about her work. Displayed below in figure 1 is a collection of sunset images that have been taken from Flickr.
Umbrico has not stopped with sunsets, utilising the process has created works based on full moon images and TV remotes. I find that the sunset images work well with the colours blending and contrasting. In looking at the image I find that it enters a “eye” game as you explore the surface moving along the lines before being stopped by a colder image which moves the eye in a different direction.

As abstraction I find this a great piece as although the image allows the individual referents to be seen clearly, however the overall work creates a new non referent image.
With the concept of appropriation in mind, I produced an image of the Eifel Tower with images found online. This image is produced in the multiple exposure method, as discussed in the post regarding Pep Ventosa. So
