The online session for 2011-10-21 is available here:
http://curvemeister.com/video/mike/2011-10-21-CmSession/2011-10-21-CmSession.html

The session is also available on youtube.

  The youtube link may change when new versions of the same video are released.

The first link is preferable because it is higher resolution.
Be sure to full-screen the video for max resolution.

The images I used for the session were kindly provided by Lowell, and are attached to this post.  I also attached the curve acv file for one of the images.

You talked about the Delta i feature.

What about the S/N feature in the sample section?

S/N is signal to noise: the average value of the sample divided by the standard deviation.  It is used for analyzing the amount of noise in the image, and for calculating the resolution of a optical system.
