Tips for slide projectors, scanning, and digitizing photo slides
A carousel slide projector displays 35mm (and other 2″×2″) slides from a circular tray, rotating each one into place and projecting it onto a screen. For most people the best option is a Kodak Carousel — like the 5600 — for its reliability and image quality, though Vivitar, Leitz, Sawyer's, and GAF models are also solid choices. Since they're no longer manufactured, you'll be buying used, typically for $50–$400 on eBay or from specialty sellers.
A slide viewer is a small device used to look at photographic slides without a projector. It typically includes a backlight and magnifying lens that allows a single slide to be viewed clearly, making it useful for sorting, organizing, or previewing slide collections.
To find local slide digitization, search for camera shops or photo labs in your area. Capture offers slide scanning with local drop-off in Atlanta and cloud delivery. For those outside major metro areas, mail-in services like ScanCafe and Legacybox accept slide carousels and loose slides with prepaid shipping.
The best slide scanner for most people is the Kodak Slide N Scan, which balances quality, ease of use, and price in a computer-free device. For the sharpest, archival-grade results, the Plustek OpticFilm 8100 leads at 7200 DPI, while budget picks like the DigitNow and Magnasonic all-in-ones cost under $70. For large or fragile collections, a professional slide scanning service digitizes everything for you at high resolution — with no manual work required.
To scan slides, you have three main options: a dedicated slide/film scanner for the best quality, a flatbed scanner with a transparency adapter for versatility, or a slide-scanning phone app for quick, low-cost results. Scan at a minimum of 2,400 DPI — 3,000–4,000+ DPI for archival quality — then color-correct and remove dust. For large collections or fragile slides, a professional service delivers the highest quality with none of the manual work.
Old slides can be digitized for long-term preservation, projected using a vintage carousel projector, donated to archives, sold on eBay, or upcycled into creative projects like jewelry, lampshades, and window art. Digitizing is the best first step regardless of what you ultimately do with them — it protects the images from further fading and makes them easy to share without needing a projector.
Photo slides are small positive images mounted in cardboard or plastic frames, developed from the lantern slides of 1849 and popularized through Kodak's Kodachrome format in the mid-20th century. They were the dominant format for sharing images in homes, classrooms, and business presentations from the 1940s through the 1980s, and millions of family collections still exist today waiting to be digitized.
Slide film, also called reversal or transparency film, develops directly into a positive image — no negative required. It's the same film often called "diapositive" film outside the US, and it's what typically fills those small cardboard or plastic slide mounts found in old photo boxes or projector carousels.
