Do It Yourself, the Hard Way
You’ll need a digital camera, a light box and a tripod for this. But if you have all three then this is probably the route for you. Just setup your digital camera on the tripod, place a slide on the lightbox, zoom in tight with your camera and shoot. Then you can shoot each of your slides, save them to your computer, do a little cropping to eliminate each slide’s white border and you’re done.
Do It Yourself, the Easy Way
Probably the easiest way to convert your slides to digital pictures yourself is to buy an off-the-shelf slide to digital picture converter. Yes, these do exist and they don’t cost as much as you might think.
You just load a slide or negative into the machine, press a button and a high resolution digital picture is made. The process is quick and fairly painless.
Plus, with a slide to digital picture converter you control the end product. If you don’t like how one of the conversions looks, just do it again.
Hire Someone Else to Convert the Slides
One final option that you have is to hire someone else to convert the slides for you. If you just don’t have time to do it yourself then by all means try to find a company that can do it for you. This is the most expensive of the three options but you won’t have to invest any of you time and you’ll get all of your slides and negatives converted.
