This summer while in the Dominican I did not bring my laptop or a projector. I brought only my Camera and my iPad. Each day I would shoot about 100 Photos from the day, designed to capture the story of the day. On my bus ride back to our dorm each night I would download the photos to my iPad. Once in my iPad i was ready to build a slideshow. My tool of choice is Photo Slideshow Director. I allows me to drag in all my photos for the day at one time,and produce a quick slideshow complete with music.
Each night as we were waiting to eat dinner, we had a chance to watch the photos from the day on my iPad. This is a great $2.99 investment for any youth worker with an iPad.
