Over on my other blog there's a snap from Wall Street, so here's another from that same area.

My wife and I took the N train to Coney Island Saturday. Right off we noted a harshness to the crowds this year, for whatever reason, and soon enough thought about leaving. After standing near the parade route for a while we decided to back away to a less-crowded area. At that point, there must have been a sidewalk closed off, sending crowds streaming back at us. As the group clogged up in front of us, some decided the way out was to jump a chain link fence.
Once on the fence, one woman froze, uncertain how to get down safely on the other side. She sat atop the fence for a while, eventually completing the jump down after some "helpful" assistance. The crowd cheered when she finally made it.

I'm much better looking in person. So much for the funhouse mirror.
On Thursday night, I taught Session One of my six-week Seriously Fun Photography course. We covered the basics on the three elements that make up photographic exposure, then touched on ways we can use these elements to control the look of our images.
Here are my notes from the session:
The f/stops to memorize are:
f/1.4 - f/2 - f/2.8 - f/4 - f/5.6 - f/8 - f/11 - f/16 - f/22If you forget these, make two columns, and at the top of the left one write 1.4 and at the top of the right one write 2.0. Now double each number as you go down the column (rounding off when needed).
Changing one stop lets in twice as much light (or half as much, depending on which direction you go. f/2 lets in a lot of light, f/22 lets in very little light. If you take a picture using f/8 and it seems a little too dark, switch to f/5.6. If you take a picture using f/8 and it is too bright, switch to f/11.
The common shutter speeds:
1/1000th of a secondNotice that the relationship of these shutter speed settings is also doubling (or halving) the amount of light that hits your sensor.
This is the ISO "speed" of a digital sensor or of film. ISO 100, 200, 400, 800, 1600 and 3200 are available on many cameras (but not all), and you should take some test shots with yours to find out if the higher ISO settings are usable or not. Figure out the fastest ISO speed you find produces acceptable shots on your camera -- you'll need to switch to it sooner or later. Notice that each ISO speed is twice as sensitive (or half as sensitive) as the next.
P = ProgramWe also addressed confirming exposure by viewing the Histogram.
A = Aperture Priority
S = Shutter Priority
M = Manual
