One of my photography professors, Juan Velasquez, an advertising photographer here in Buenos Aires, has tatoo’ed on his arm all the f-stops from f1 to f90. I totally suck in comparison!
The class, fyi, is Fotografia Publicitaria at Espacio Buenos Aires, a fashion and design school. It’s basically an intermediate studio lighting course where one week we’ll photograph a bottle of red wine and the next a pint of beer. Their photography courses have a very professional [rather than artistic] orientation, which I actually appreciate.
