It's a long time since I've done any developing, 70's, film and developing by post wasn't cheap. So we took great care with every frame on Kodachrome 25 and 64. Finally three of us clubbed together and got some kit, but producing two A4 pictures correctly in colour was an all evening effort. With three people wanting to print pictures after a weekends photography, it soon led to frustration and claims of "It's my spare room, so I get first priority" that didn't last long!
Even now after 20yrs of digital, I'm still careful of just taking loads of shots. I mostly run the camera in manual mode as I'm in no rush for most things that I point the camera at. Editing, apart from crop is also a rare thing. I haven't used the a6400 in B&W yet but your photos have woken an old interest, when I used a large plate camera to take pictures of the same subject in B&W and then Polaroid sheet colour. The old lenses not being colour corrected gave a softening effect.
