Logo, yes. But isn't that technically a splash page?

So my answer is actually splash page; using your logo. Splash page should also have a link-to-blog, granted the photographer has one.
And I definitely wouldn't use a blog or an image gallery as the
front page? to my main site. A link to each other I can understand, but I wouldn't consider it a front page. I feel that would undermine the significance of the blog, or vice versa, the site. I feel they (site and blog) should be treated as two separate sites, even if they relate to the same business. That's just me.
