I’m wondering if there are any specific tips for finding perfect focus on the film grain. I use a Fuji X-E4 (APS-C) with the Micro-Nikkor 55mm f3.5 Ai adapted along with the PK-13 adapter. The camera is mounted on a Negative Supply copy stand, and the film is run through the 35mm basic holder on top of their 99 CRI light source.
I’ve enabled focus peaking (Yellow, High) and it just seems so damn difficult to find that “perfect focus” on the film grain. I can’t tell if I move the focus a little one way or the other what’s more “accurate” in comparison tests I’ve run. Am I overthinking it? When do I know when it’s “good enough”? Where should I be looking in an image to find the best grain to focus on? The highlights or the shadows (aka, the denser part of the negative or vice versa)?
