My father was an incredible amateur photographer who left us with all of his work. We now have literally hundreds and thousands of slides from family events, vacations, and the sort. My goal is to scan them to my computer and burn a DVD for my family, most importantly my mother. Is there a suggested method, device, or service that will help get all these slides to the right format with good quality? Should I purchase a 35mm slide scanner just for this project or is there another way?
