I am in need of expert advice? Have you seen the Gatoraide commercials where people sweat and it is the color of the Gatoraide that they are drinking? My husband is a football coach and I have taken individual pictures of each of his 10 seniors. I would like to add sweat to the pictures and color the sweat blue and then print "Royal Pride.....Is it in You?" I need to get these done ASAP for graduation open houses. Any ideas on photo editing software and the steps I would take to do this?
