If you don’t have an app to add a filter why not use something real instead? Here I used some crumpled plastic wrapping paper to put over the top of my abstract drawing of a face. It almost looks like the lines are printed on the plastic. Remember, experiment, have fun!
When I took this photo it was dark and underexposed. I decided to change it with a black and white filter but was going to delete it from my phone. Then I decided to put it through a texture filter, still not satisfied I added a lens flare to the handle. I’ve decided not to do any more to it.
The question is if you had to do something with the original what would you do? Here’s the plain black and white version.
