Wow! We didn't have this when I was in cubs! Rather than learning the processing end yourself and then teaching it to the cubs, try contacting a local community college. See if they have a photography class. Ask the instructor if he and his class would be willing to handle the processing end for you (gives the students good practice and it is good community volunteer work). You can go over with your cubs what it takes to do processing without having to do it. If they are really interested, you might be able to arrange a field trip to the local community college and have the instructor give a demonstration.(posted 8599 days ago)This project sounds like a one time thing (or maybe once a year). Holding the attention of cubs for a long time is a challenge as well as the time constraints (once a week for two hours or so). Whet their appetites and if they want more, they will surely let you know!
