Just a brief mention of two items that may be of interest.
The first is, I created a webpage about understanding the aperture within your camera – what it is, how it works, what it does for your photos, and so on. Lavishly illustrated and a nonstop rollercoaster ride from start to finish, it can be found at http://wading-in.net/Tips/aperture.html.
The second is, I’m selling one of my cameras, a Mamiya 645E, so if you’re interested, especially if you’re interested in starting in medium format, check out http://wading-in.net/Add/mamiya.html. If that page is down, it means the camera has been sold.
I’ll be back shortly with more real content!
