They say smell is the most powerful trigger for memories. I grew up in Burbank, California and the smell of cut grass in the breeze on a summer day will instantly teleport me to the early 1970s. The tar smell of a German train station, or a fresh pretzel from a bakery. Wet creosote. A churrascaria in Brazil. I don't know how to capture a smell so here we are.
I don't why I picked up a camera at about age 10 and thought I like this. I used a Kodak Instamatic with flashcubes and the film in a cartridge, 126 I think. My grandfather gave me a Voigtlander rangefinder when I was 12. I shot Agfachrome. Lots of cameras after that, film to digital, back to film. The smell of fixer will go with me to the next world.
I took lots of selfies before there were selfies. I think of them as self-portraits, just another snapshot in time. Velazquez or Rembrandt didn't paint selfies.
I read somewhere once that photographers take the same photo over and over, just the details are different. It's not the same in a literal sense of course, but the same attitude, along with light, color and form.
