Mount Tamalpais from Corte Madera Creek, photo by Harold Davis. View this image larger.

A long, happy, tiring, and exciting day began for me with a visit with my three boys to Katie in the NICU. I then spent the afternoon giving a digital landscape photography workshop to full house of enthusiastic photographers under the auspices of the Point Reyes National Seashore Association.

If you are interested, I’ll be giving this one-day digital landscape photography seminar again on October 26 in the Red Barn at the Point Reyes visitor center. I’ll post more information once a registration link is available.

Afterwards, as darkness covered the landscape, Mark and I wandered around taking pictures.

This image is from the tidal flats near Larkspur, by the banks of the Corte Madera Creek, looking back towards Mount Tamalpais. I was trying for a frontal view of San Quentin prison at night from the mud flats, but saw this neat night vista behind me.

While it was pretty much night, there was plenty of ambient light from the Marin cities, as well as a half moon. The interest for me in this photo was the way the various kinds of light mix to make an interesting melange of colorful night.
