Thanks to James Tanner for the four-part series of articles on how to take better photographs. The series appears in his Blog: Genealogy's Star.
The landing page takes you to the fourth and final article in the series, but if you scroll to the bottom of the landing page, you will find links for the preceding three articles.
James has other blog posts dealing with photography, and a search of the blog index will reveal them. If you do such a search, take your time and enjoy the many things the Blog has to offer.
