At our recent Lumi Build Day, we decided to make a pop art themed piece as a tribute to the founders of our makerspace. The important part was getting the negatives just right so we could get more of a painted on look than an actual photo and the right features were visible.
Things you'll need Inkofilm A computer running GIMP An inkjet printer A nice digital photo
I'm choosing GIMP because it's free and available on all operating systems so there's no reason for you not to have it :) You can download it from www.gimp.org
To make things easier, make sure you choose a picture that has a lighter background and you have a clear shot of the persons facial features. The best pics are casual portraits where the subject is unaware
