In class we are getting used to using a variety of computer aids; iPads, iPhones or other tablets such as Android and Google. We use them as a visual resource and to carry around our class photos to work from. There is so much you can do once you have taken a photo and the video below from the SyncSisters on YouTube demonstrates how you can change your photo, crop it, put it into black and white and lots of other things. Don't forget to save it!
Do this before you load it into the Waterlogue or other photo app for painting so, for example edit your photo into black and white from colour before seeing what you can do in the Waterlogue app.
