  1. sometimes I wish I could just have you over for a few all day lessons, but this is the next best thing.

  2. Wow. Depth of field stuff difficult. I think I finally get the apeture/f stop thing - I have a Canon non-digital that offered an automatic or manual option and I always used to chicken out and choose automatic.
