Using a photo which holds a significant memory is a helpful tool in so-called art therapy and one's journey through grief. In the example here, the mother of a teen who was killed last year works with a photo she took while she was taking her son on a ski trip.
Place the photo in an acetate sleeve and tape to work table. Position gel plate. Mix retarder into your acrylic paint to slow down the drying process and then quickly paint your image using a generous application of paint.
Press a sheet of watercolor paper and pull the print. You could pull a second "ghost" print; spritz the plate with water and them pull a third and possibly fourth print. These can be adhered into an altered book art journal as backgrounds for future reflection.
