Scanned slides with a camera

Following Alans lead, I set up my Canon R5 with a 35 f1.8 macro lens and two extension tubes, a 13mm and an 18mm. This allows 100% magnification.

I use a tripod and my pano rail to mount the camera. I also have a 4x5 Logan light table to provide the light. I added a slide holder which I taped to the light table to position the slide. I used shims to level the slide holder and a camera level to level the camera. It’s pretty Rube Goldberg but it works.

My slides are not too good. I always thought they were out of focus, but after scanning many of them, I see that they are just soft. Many were shot with an old low end Tameron 70-210 that was not a sharp lens and I tended to use f32. Some of my images were not too bad, and I suspect they were shot with my Nikon 50mm f1.8.

I used a Varity of films, Kodachrome 24 and 64, and Fuji 400. Grain is visible in all but really bad in the 400. I find that for the really noisy sky’s I can mask the sky and in ACR reduce texture 100% and get a decent look. Nr seem to have little or no effect on this grain.

Even though I stored these in acid free sleeves, there is lots of dirt on them. I clean each slide before making an exposure, but some require a lot of post processing clean up.

I find that the slides don’t need a lot of correction with respect to WB or saturation. Its mostly a process of clean up, increasing DR and sharpening.

The funny thing is when I get it set for 100 magnification on one slide, the next may be less. I have found my best results are when I work at about 85% magnification. I am still getting around 7000 pixels on the long end.

They all look soft compared to my digital images, but some have memories that cannot be repeated. It has so far been a fun experience. I have done about 100 from a 20 year collection.

I am showing a few samples that are not too bad, but saving my best for the presentation forums.

A few from Butchart Gardens in 1998.

You have a pretty good setup Ben as it seems to work really well.

I like these! They look great on here. I don’t detect any softness, and I guess if there was it would be pretty easy to add some sharpness.

Pretty nice set from what I can see with my browser window. I like the garden images and the old barn with the steam rising off the roof.

Have you run any of these through Topaz Denoise AI and Sharpen AI? That combination can really clean up some messy slide scans.

Thanks Jim, of course downsizing for web tends to eliminate some of the softness.

Thanks Alan, I have run these in Topaz denoise AI and it has minimal effect. Its grain not noise and I find that ACR textures has the bigger effect.

Yeah - film grain is very hard to mitigate and Denoise AI is not the best solution to handle that. I mostly shot with Kodachrome 25 after getting burned by Agfachrome in the mid 70's. Even the ISO25 has some grain and looks dirty compared to what we get now out of our DSLRs.

Some people call it the "Film character" and clamor for it. It is easy to add it to digital files for those who like. Hard to get rid of from film. So there is that.

I have never understood that desire, just like I cannot for the life of me understand why people want to hear all the noise and distortion in vynal recordings.

For the record, the Buchart Gardens images were shot using Kodachrome 64 and probably my Nikon 50 f1,8. The barn was probably Kodachrome 25, and the Tamron lens at around 125mm f 32. It is much softer than the Buchart images.

I am always amazed that people want to pay money to have their captures look worse.

I got a lot of lessons about film grain back in to 70's when I was working in Middle Eastern Archaeology and could only study our excavations finds from pictures I took during the field season. I spent a lot of time studying my slides under binocular microscopes since we couldn't remove the materials from Jordan (a constraint I fully agree with). It was hard to ignore the limitations of film under those circumstances and it made me concentrate on getting the most out of my captures.
