After looking through a lot of my camera-scans of 35mm b&w negatives from the past few years, I can say I was able to make an improvement in sharpness by reducing camera-shake. But I can't say for sure which improvement to my system made the most difference: switching from a tripod to a copy stand - or getting a brighter light source which gave me shorter shutter speeds. I was also able to get some additional improvement but upgrading my lens.

tl;dr
In my very first set-up I mounted my Fuji XT-1 camera to a tripod with inverted center column <photo here>. And my light source was a generic LED light panel. At my camera's native ISO of 200, and stopped down to something like f/11, my typical shutter speeds were 1/3rd to 1/6th second. After sharpening in Photoshop, I thought the quality of those images was not too bad. But we always hope for more.

Next, I replaced the tripod with an ALZO Copy stand, and 4 months later I replaced the generic LED panel with a brighter one. With the brighter light, I was able to use shutter speeds in the 1/80th - 1/150th sec range. My camera-scans were definitely a little sharper after these two upgrades. But I can't say for sure if one helped more than the other.

I started out using a Schneider-Kreuznach Componon-S 5.6 / 100mm Enlarger Lens on a bellows. I think I paid $40US for the lens in 2019 (eBay). In 2020 I switched to a Rodenstock APO-Rodagon D 75mm f/4.0 which I bought on eBay for $160. The improvement in sharpness was not huge because the enlarger lens was already doing a pretty good job. But I did see a decernable improvement in the fine details. With the Rodenstock APO lens I am now doing much less sharpening in post-processing - in many cases, none, other than Lightroom defaults.

For the large portion of the world that rarely texts, and never texts things like this, it apparently isn't just errant key strokes, but instead you will find if you research it that it actually is intended to mean something 😉

In my posts, you can never be sure. One of my cats managed to post something very similar. ;-)

This is what I used before I got a scanner (I stil have it, you never know).
