If you’ve found a box of old 35mm slides and you’re wondering how to get them scanned, where to send them, what resolution to choose, and whether you’ll get the originals back, you’re asking exactly the right questions.
That’s what Gregg D. wanted to know when he wrote: “I have a few hundred slides from the 1982 trek in the Himalayas. Describe how I get them to you, and how you process and return them. Looking for 3000-4000 dpi.” And honestly, that’s the same question many people have when they find slides from travel, family vacations, or once-in-a-lifetime moments that have been sitting unseen for decades.
Old Slides in a Box? Here’s Exactly What to Do
If you have a few hundred standard 35mm slides or thousands, one of the easiest ways to get started is with the Slide Scanning Box from ScanMyPhotos.com. It holds up to 540 slides, and after you place your order, a prepaid box is mailed to you. You fill it with your slides and send it back for scanning. Right now, the prepaid box is listed at $156.75, reduced from $275, and it includes free shipping and handling for U.S. domestic orders.
That simplifies the process much more than trying to package everything yourself or guessing where to send it. You place your order first, the box arrives, and then you send your slides using the included shipping setup. Once your slides arrive, they are scanned onsite in Irvine, CA. This matters because when mailing irreplaceable originals, people want to know exactly where they’re going and how they’re being handled. If your slides are especially important, many customers also include their own GPS tracker, such as an Apple AirTag, in the box for added peace of mind during shipping.
For a collection like a 1982 Himalayas trek, 4,000 dpi is the better choice.
ScanMyPhotos offers both 2,000 dpi and 4,000 dpi scanning. If your slides include travel scenes, landscapes, mountain views, people, or details you may want to zoom into later, 4,000 dpi preserves much more of the original image. That means better detail, better enlargements, and a better long-term archive. In other words, if these slides matter enough to digitize once, they’re worth digitizing well.
After scanning, your files are provided digitally through an online download link. Optional add-ons, such as a thumb drive and Photo Index Album, are available if you want extra copies or easier organization. And yes, your original slides are returned to you once the scanning is finished.
That’s the part many people want to hear most.
You’re not giving up the originals. You’re simply making them viewable, shareable, and protected.
And there’s a bigger reason why this matters now. A KTLA-TV segment highlighted the discovery of lost 35mm promotional slides related to Los Angeles television history, showing how valuable old slide collections can be once they’re digitized and viewed again.
That’s really the point. Whether it’s lost Los Angeles broadcast history or a trek through the Himalayas in 1982, old slides often hold moments no one has seen in years, and in many cases, they might be the only copy left. So the simple answer to Gregg’s question is: order the Slide Scanning Box, select 4,000 dpi, pack your slides when the box arrives, send them in with the included shipping label, and they’ll be scanned, uploaded, and returned to you.
If those slides made it this far, they’re worth seeing again.
