So here I have taken some basic images on paper of a bag (infamous bag-see other post!) and basically edited them slightly. You can see the colour change in each one. You can use a basic smartphone photo editor that is pre-installed on your phone. This way the photos remain simple to edit and the features on the editing programme become your art tools.
Simple
Have a go today with whatever art images you want to take with your phone, perhaps! Edit them and then compare them. It’s a good place to start.
PS my twitter name is You, Sir! This is what I use for my Mexican street artist name.
