I use a 35mm lens.
Most of my photos are not retouched and if so, I use it's with wise parsimony.
Working in black and white is relaxing to my eyes and my brain but I really enjoy working with colourful photographs when the natural light makes them breathtaking.
P.S. Want to learn about "otium"? Here is a book in French about the word (yes, a book about one word): Recherches sur l'Otium Romain, Jean-Marie André, 1962.
