We went to an event at Swissnex, located at a pier on Embarcadero in San Francisco, California. After that we took Weimo, a self-driving robot taxi to a cozy jazz bar on Broadway. It was pretty dark in the room, perfect for a shot with the extremely light sensitive vintage Dream Lens.
I processed a balanced and a smooth HDR photo from a RAW exposure, blended them selectively, and carefully adjusted the color balance and curves. I welcome and appreciate constructive comments.

Fractals show self-similarity, or comparable structure regardless of scale. For example, a small piece of Romanesco broccoli, when viewed up close, looks the same as a larger chunk. In this photo you see buds with spirals that flow in two directions. If you zoom out you again see spirals that flow in two directions.
The branched tips of a bud, called meristems, make up a logarithmic spiral, and the number of spirals on the head of Romanesco broccoli is a Fibonacci number, which in turn is related to what's known as the "golden ratio."
The 13th-century mathematician Leonardo Pisano's nickname was "filius Bonacci" (son of Bonacci), which got shortened to Fibonacci. In his 1202 treatise, "Book of Calculation", Fibonacci described the numerical sequence that now bears his name: 1, 2, 3, 5, 8, 13, 21... and so on, where each number is equal to the sum of the preceding two numbers. Divide each number in the sequence by the one that precedes it, and the answer will be something that comes closer and closer to 1.618, an irrational number known as phi, aka the golden ratio (eg, 5 divided by 3 is 1.666; 13 divided by 8 is 1.625; 21 divided by 13 is 1.615; and so on). And there is a special "golden" logarithmic spiral that grows outward by a factor of the golden ratio for every 90 degrees of rotation, of which a "Fibonacci spiral" is a close approximation.
About this photo: In February I gave a photography class at the Embarcadero in San Francisco on behalf of the Digital Photo Academy. We walked in the halls of the Ferry Building to try one-point perspective shots. Then we went outside to practice rule of thirds and street photography at the Ferry Plaza Farmers Market.
I processed a realistic and a balanced HDR photo from a RAW exposure, blended them selectively, carefully adjusted the color balance and curves, and enlarged the image with Topaz Gigapixel AI. I welcome and appreciate constructive comments.

A photographer friend and I took photos at the Holiday Party at the headquarters of Atmo AI in San Francisco, California. The company provides AI-based weather forecasting systems for governments. To celebrate a recent design win they played a recording of the low rumbling sound of a recent rocket launch using 60,000 watts subwoofers at the party! The dress code was galactic black-tie. The guests delivered -- they came with very creative outfits. Late at night the party was in full throttle.

On the way back to the San Francisco Bay Area from Nevada we planned to have dinner at the iconic Harris Ranch in California's Central Valley. Before dinner we made a small detour to visit a ranch in Coalinga. We arrived just as the sun went down. Cattle running around created a lot of dust.

Last Friday night we went to see Hanami, the cherry blossoms at Hakone Gardens, a Japanese garden in Saratoga, California. It was an enchanting experience to walk below cherry trees in full blossom. This is the Upper House seen from the pond. A Double Weeping Cherry tree is on the right.
