One commonly overlooked tip that is especially prevalent with photography sites is to ensure that your site has rich text content. It's one thing to get eventually linked to your site but once google is then enumerating through the pages of your site it needs an 'anchor' to determine your rankings. For this is uses 'keywords' and the more text content you have, the more chance your site will display in the ranking lists when people are looking for particular content.
Take a look at your photography and where you are going with it, or the types of pictures you take and write a few paragraphs and somehow get it down on that page.
Seriously, it will make all the difference to your search rankings.
