Do you have slides and negatives in your photo collection? Are you unsure of what to do with them? Most photographers – pro and amateur alike – switched to digital in the early 2000s, so this format can appear ancient. But both 35mm color slides and 35mm negative film (both color and black + white) have been around since the mid-1920s. Slides and negatives may be the only existing copy of family images you have. They are also the originals. If you wish to view and preserve them, it helps to have a few tools.


Since you probably don’t need to scan everything, using these tools can help you decide which ones to scan. 

• A photography loupe.This small but mighty magnifier allows you to see the detail in these small formats.

• A light box. This is a viewing table with backlighting. They come in flat or angled versions. We use the EZ View Slide Sorter  which is angled, but the Huion L4S LED is an inexpensive choice for home use. Of course, you can also use an iPad in a pinch!

• The Negative Me app allows you to view negatives as positive images. The colors aren’t always exact, but it’s close enough.

Scanning Negatives

When we work with 35mm negatives, we scan at a high PPI (in combination with at least a 400% enlargement). This creates a richer, more detailed image. Scanning from negatives is ideal because the negative is the original source material, as previously noted. There is more leeway than with a print (which is the second generation).

Remember the Kodak Disc Camera from the early 1980s? The negatives were tiny! Because of that, they lack the information for a good quality print. The Disc camera fell out of favor for good reason. The prints were grainy and soft, and the colors were dull. I shudder to think how many important family photos exist from this source. But we can still scan from these negatives and yield better results than what you originally got from machine prints.

Contact Sheets

Before digital photography, I worked in a darkroom as a photographic printing technician. Since 35mm negatives were the most popular types of film, I spent much of my time creating contact sheets. This allowed clients to view the images in a grid on one sheet of paper before committing to individual prints. These days, digital versions are available. This makes it easy to choose which images to scan. If you only have 35mm negatives, this solution is a great way to address that issue.

Some older photo collections I’ve worked with have contained larger format negatives. These range from 120mm to 8×10″. Scanning these results in better images since they are larger than 35mm film (larger format = more detail). 

Scanning Slides

Slides are positive images and are usually housed in plastic or paper frames. They can be various sizes, though the most popular is the 35mm version. The best way to view slides is using the aforementioned loupe and lightbox. We use the same method of scanning slides as we do negatives. The beauty with scanning slides is that the original colors, which often fade or change over time, can be improved with software (we use Lightroom and Photoshop). We can also make digital contact sheets for slides, though that’s not as important as it is with negatives since they are in a positive format and easier to view.

Here’s an example of what you can do once you’ve had your slides scanned.
