Here are two more photos I took at last night's camera workshop. I wanted to take something slightly more beautiful than a selfie, so I chose the Luxo statue outside the Steve Jobs building at Pixar, and some white flowers from the garden. Both were taken rather late in the day, under partly cloudy skies using a 4 second exposure on some paper with an ASA value of around 4, and a 4 second exposure (timed by my accurately counting "Mississippis"). Both were shot at f/24. I scanned them using our copy machine at 600dpi, and then inverted them in gimp. I didn't do any further processing on the Luxo. With the flowers, I adjusted the curve slightly to bring out some details in the darks between the flowers. I saved these versions as JPEGs, click on them to see them full resolution.
If you look to the upper right of the Luxo, you can see that there are some significant off-axis aberrations, as is also apparent in the background of the flowers. But the center of the field is remarkably sharp, considering. I'm rather pleased.
