I had a small studio on the second story of a crumbling downtown building that used to be called (no lie) the California Hotel. We had neither heat nor air conditioning but we did have laughably cheap rent, and I had a wonderful window to the north. I built my portrait lighting designs around that window.
In this case I loved the portrait so much that I subsequently dated, and then married the subject. I took this photograph back in 1979. About 36 years ago.
We obsess about gear (me at least as much as everyone else) but this was done with a Mamiya C220 camera with an ancient 135mm f4.5 lens. Could I do better now? Not very likely as there was nothing I wanted to improve upon. I still don't.
If you don't love your images maybe you just aren't pointing your cameras at the right subjects....
