If you have many slides ( or your friends and family have many) then consider the Nikon slide holder with its own white diffuser.

I use it on all three common formats but if your gear isn’t FF then you need a bit of creativity and an extra $20.

It fits directly onto some FF macro lenses. Otherwise you need a stepping ring (up or down) and some spacers (“antique” Nikon macro tubes repurposed).

In the attached pic, you see, left to right:
1. m4/3 body (80MP by sensor shift).
2. m4/3 macro lens set to 1:2, NOT 1:1.
3. Spacer tubes to put slide at the proper distance for sensor smaller than the slide.
4. Nikon slide holder.

The whole system is one solid package. No tripod needed.

Interesting, but seems to be out of stock everywhere except eBay, and almost all of those are shipping from Japan. What is the light source for this?

Very simple - wax paper?

Good idea, maybe a few layers. I’ve just never tried it, mainly cuz I never have it around. I have used bakers’ “parchment paper” in a single layer. That works very well. Built a quick tent with it for jewelry pix. Clean color as best I recall.

I am trying to photograph a 35mm slide. I have a macro lens mounted on my D500. The slide is attached to my computer monitor over a blank white spot to provide a backlight for the slide. The camera is on a tripod with the lens about 1½" from the slide. Using various f stops, white balance settings and ISO values, they all have very fine crosshatch lines. The lines run both directions, forming tiny squares, and are much more noticeable in some of the photos than others but are visible in all of them.

I am considering two possibilities: I am picking something up from the monitor or it is in the slide itself. No, I have not tried this with another slide. I probably should, but I got discouraged after a couple of hours and put everything away.

Any ideas?

Try one of these: Light Pad Light Box Ultra. They come in many sizes. I bought the large one for $21.59. Hard to build one for less money than that. And I am using this for copying slides. Very even light source.

I bought an Artist Light box from Amazon but was disappointed by the granularity of the LED's.
I have not yet tried a white filter.

I DO have a Lightbox application for my Android that may work...

I think you will have the same problem with the Android phone as the monitor produces.

I got out the Light Pad Box that I gave the link to earlier, and then gave it a try. The top surface is a translucent plastic. First image I found a tiny spec on the screen to give me something to focus on as it was impossible to focus on the screen itself as there was nothing to judge my focus.

For the 2nd image, I held a pen in front of that spec just to give some size to what I was focusing on.

Also on the second image, I stopped down quite a bit to get the pen more in focus, and I can see some faint scan banding that didn't appear when at f5.6.

Can't argue with that ... Imma getting one myself, since I have my home made one away. I just form a BUNCH of slides buried in a closet.

A diffuser will help, but most homemade diffusers have microstructure that will show up if you focus on the diffuser. For that reason there should be significant separation between the diffuser and the slide being copied.

User ID gave a very good solution. The pixels comes from the screen not the film. A diffusion sheet would smooth out the light.

Another way to do it is to keep the lightsource further away from the slide, so that the camera focus/sharpness would be on the slide the lightsource in the bokeh zone.

Great Idea!


I sat in my garage with the big door open, and used outdoor natural lighting for background--worked fine.

For anyone who is still following this thread, I have achieved success.

I purchased a small viewer so I could have a quick look at any given slide to see if I wanted to digitize it or not. That works well.

I also purchased a Nikon ES-2 Adapter. It does the job far beyond my expectations and I am very happy with it and the results. Here is one of my first efforts. This is a shot of the Acropolis taken in 1964 on 35mm slide film. It could be a tad sharper but I didn't know much about photography back then so it is what it is.

Thank you to everyone for suggestions, comments and ideas. I am now a happy camper/photographer.

Looks good. Now it's ready for the healing brush to remove the dust in the sky. You can clean that up quite a bit.

Or better yet, brush away the dust and dirt with a soft camel's hairbrush and to then use a squeeze bulb blower to blow the remaining dust and dirt.

And by the way, Topaz Sharpen AI can actually work on scanned slides too and can add a bit of sharpening. Just don't over sharpen. Stop before the sharpening starts to generate artifacts.

Looks like a lot of dust on the slide or scratches. Here is an article you might like to read.

Good stuff. Thank you. One reason the dust is still on the example photo is that I wasn't sure how to properly clean it. This helps tremendously.
