I took my regular visit to my favourite city-centre coffee shop and when he served me the guy behind the counter said "Have you taken any good snaps yet today?". I hadn't, but whilst I sat there with my coffee and Danish this scenario appeared in front of me. It is a candid image, and they did not notice me at any time. I used my M240 fitted with the 50mm Zeiss Sonnar f1.5 and I was working at 1,000iso. Exposure was 1/60th @ f6.8. post-processing was in Lightroom Classic.
Hope you like it!
