Mushroom stand in the San Francisco Ferry Building. We bought dried Shiitake mushrooms and some truffle-mustard spread.
It’s fascinating how many varieties of mushrooms exist…way beyond what you see at markets. Fungi! :)
Aperture can be thought of as the opening that lets light through – where light travels. Aperture on a camera is like the pupil of the eye. The larger the aperture number (f-number/f-stop), the smaller the opening. For example, f/8 is smaller than f/2.8 in terms of opening size.
