Every so often it happens. I was using my tripod on a tripod to do some HDR frames with the D850 + 24TS, in a deserted courtyard. Sombody came up to me and asked if the pictures were for professional use. No, I said, I just like doing things properly, I added.
I am amazed there are still people who believe they have come across sombody who is going to make a ton of money, selling photographs of their obscure monument.
Why does a tripod seem to equate with professional photography?
