My first time shooting a film stock with an insane iso like this, previously I hadn't gone for anything higher than iso 400 and mostly colour. I also pushed myself a bit out of my comfort zone with the 28mm, as I rarely feel comfortable shooting below 50mm.
Somehow this was the only shot of the roll that seemed properly exposed, with many others mildly or wildly underexposed. I've since checked the lightmeter of my XG9 against other references at 3200 iso (or rather 1600 iso -1 stop because the XG9 doesn't support 3200 iso). But unless I push it way harder than I'd ever do irl, I see no fault there. Edge markings and this shot are also fine, and the camera has previously behaved normally, so it was probably just a skill issue somehow.
On the plus side, thin negatives are easier to scan. But I do you do your development yourself. BW development is fun, easy, and makes you feel like a hero.
Then get the lab to do the prints. Even Ansel Adams had people do prints for him. He'd get proof prints and circle in red the areas he wanted dodged and burned and by how much.
